[libvirt] [PATCH] vircommand: fix polling in virCommandProcessIO
by Roman Bogorodskiy 22 Apr '15

22 Apr '15

When running on FreeBSD, there's a bug in virCommandProcessIO polling that is triggered by the commandtest. A test that triggers EPIPE in commandtest (named "test20") hungs forever on FreeBSD. Apparently, this happens because FreeBSD sets POLLHUP flag on revents when stdin in closed. And as the current implementation only checks for POLLOUT and POLLERR, it ends up looping forever inside virCommandProcessIO and not trying to do one more write() that would trigger EPIPE. To fix that check for the POLLHUP flag along with POLLOUT and POLLERR. --- src/util/vircommand.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/util/vircommand.c b/src/util/vircommand.c index 648f5ed..f9b3c3f 100644 --- a/src/util/vircommand.c +++ b/src/util/vircommand.c @@ -2097,7 +2097,7 @@ virCommandProcessIO(virCommandPtr cmd) } } - if (fds[i].revents & (POLLOUT | POLLERR) && + if (fds[i].revents & (POLLOUT | POLLHUP | POLLERR) && fds[i].fd == cmd->inpipe) { int done; -- 2.3.5

[libvirt] [PATCHv2]rework the check for the numa cpus
by Luyao Huang 22 Apr '15

22 Apr '15

V1 discussion: https://www.redhat.com/archives/libvir-list/2015-April/msg00919.html new for v2: remove 1/2 because no need introduce a new flag to avoid the broken introduced by the new check. We introduce a check for numa cpu total count in 5f7b71, But seems this check cannot work well. There are some scenarioes: 1. one of cpu id is out of maxvcpus, can set success(cpu count = 5 < 10): <vcpu placement='static'>10</vcpu> <cell id='0' cpus='0-3,100' memory='512000' unit='KiB'/> the cpus '100' exceed maxvcpus, this setting is not valid (although qemu do not output error). 2. use the same cpu in 2 cell, can set success(cpu count = 8 < 10): <vcpu placement='static'>10</vcpu> <cell id='0' cpus='0-3' memory='512000' unit='KiB'/> <cell id='1' cpus='0-3' memory='512000' unit='KiB'/> I guess nobody will use this setting if he really want use numa in his vm. (qemu not output error, but we can find some interesting things in vm, all cpus have bind in one numa node) 3. use the same cpu in 2 cell, cannot set success(cpu count = 11 > 10): <vcpu placement='static'>10</vcpu> <cell id='0' cpus='0-6' memory='512000' unit='KiB'/> <cell id='1' cpus='0-3' memory='512000' unit='KiB'/> No need forbid this scenario if scenario 2 is a 'valid' setting. However add new check during parse xml will make vm has broken settings disappear after update libvirtd, so possible solutions: 1. add new check when parse xml, i chose this way in this version. 2. add new check when start vm. I think this is a configuration issue, so no need report it so late. 3. just remove this check and do not add new check... :) Luyao Huang (1): conf: rework the cpu check for vm numa settings src/conf/domain_conf.c | 6 +----- src/conf/numa_conf.c | 37 ++++++++++++++++++++++++++++++------- src/conf/numa_conf.h | 2 +- 3 files changed, 32 insertions(+), 13 deletions(-) -- 1.8.3.1

[libvirt] [PATCHv2] qemu: Fix issues with maxMemory in qemuDomainSetMemoryFlags()
by Peter Krempa 22 Apr '15

22 Apr '15

From: Luyao Huang <lhuang(a)redhat.com> qemuDomainSetMemoryFlags() would allow to set the initial memory greater than the <maxMemory> field. While the configuration would not work as memory hotplug requires NUMA to be enabled and the qemuDomainSetMemoryFlags() API does not work on NUMA guests this just fixes a corner case. The fix is still worth though as it allows to induce an invalid configuration and make the VM vanish on libvirt restart. Additionally this tweaks error message to be more accurate.

[libvirt] [PATCH 00/11] caps: various internal cleanups
by Cole Robinson 21 Apr '15

21 Apr '15

First two patches are straight bug fixes. The rest is a bunch of internal cleanup I felt compelled to do. Summary is - Switch caps and domain to use an enum for os.type value (hvm, xen, exe, ...) - Switch caps to use VIR_DOMAIN_VIRT* internally - Add a single function for looking up domain XML relevant values from capabilities, and test the crap out of it. - Use that function to simplfy and improve a lot of code. Thanks, Cole Cole Robinson (11): domain: conf: Better errors on bad os <type> values domain: conf: Don't validate VM ostype/arch at daemon startup caps: Use an enum internally for ostype value caps: Switch AddGuest to take VIR_DOMAIN_OSTYPE value domain: Convert os.type to VIR_DOMAIN_OSTYPE enum caps: Convert to use VIR_DOMAIN_VIRT internally caps: Add virCapabilitiesDomainDataLookup domain: conf: Do ostype/arch/machine parsing earlier domain: conf: Use CapabilitiesDomainDataLookup for caps validation caps: Use DomainDataLookup to replace GuestDefault* domain: conf: Drop expectedVirtTypes src/bhyve/bhyve_capabilities.c | 6 +- src/bhyve/bhyve_driver.c | 5 - src/conf/capabilities.c | 307 ++++++++++++-------------- src/conf/capabilities.h | 50 ++--- src/conf/domain_audit.c | 2 +- src/conf/domain_conf.c | 331 +++++++++++------------------ src/conf/domain_conf.h | 25 ++- src/conf/snapshot_conf.c | 18 +- src/conf/snapshot_conf.h | 2 - src/esx/esx_driver.c | 12 +- src/hyperv/hyperv_driver.c | 4 +- src/libvirt_private.syms | 6 +- src/libxl/libxl_conf.c | 14 +- src/libxl/libxl_domain.c | 7 +- src/libxl/libxl_driver.c | 8 +- src/libxl/libxl_migration.c | 2 - src/lxc/lxc_conf.c | 8 +- src/lxc/lxc_controller.c | 1 - src/lxc/lxc_driver.c | 7 +- src/lxc/lxc_native.c | 4 +- src/openvz/openvz_conf.c | 7 +- src/openvz/openvz_driver.c | 7 +- src/parallels/parallels_driver.c | 23 +- src/parallels/parallels_sdk.c | 6 +- src/parallels/parallels_utils.h | 2 +- src/phyp/phyp_driver.c | 10 +- src/qemu/qemu_capabilities.c | 21 +- src/qemu/qemu_command.c | 29 +-- src/qemu/qemu_domain.c | 1 - src/qemu/qemu_domain.h | 6 - src/qemu/qemu_driver.c | 14 +- src/qemu/qemu_migration.c | 5 +- src/security/virt-aa-helper.c | 9 +- src/test/test_driver.c | 12 +- src/uml/uml_conf.c | 4 +- src/uml/uml_driver.c | 6 +- src/util/virerror.c | 5 +- src/vbox/vbox_common.c | 23 +- src/vmware/vmware_conf.c | 8 +- src/vmware/vmware_driver.c | 4 +- src/vmx/vmx.c | 3 +- src/xen/xen_driver.c | 5 +- src/xen/xen_hypervisor.c | 4 +- src/xen/xend_internal.c | 6 +- src/xenapi/xenapi_driver.c | 20 +- src/xenapi/xenapi_utils.c | 4 +- src/xenconfig/xen_common.c | 64 +++--- src/xenconfig/xen_sxpr.c | 5 +- src/xenconfig/xen_xl.c | 17 +- src/xenconfig/xen_xm.c | 12 +- tests/Makefile.am | 8 +- tests/domainconftest.c | 3 +- tests/domainsnapshotxml2xmltest.c | 1 - tests/lxcxml2xmltest.c | 1 - tests/openvzutilstest.c | 2 +- tests/qemuagenttest.c | 1 - tests/qemuhotplugtest.c | 1 - tests/qemuxml2argvtest.c | 1 - tests/qemuxml2xmltest.c | 3 +- tests/qemuxmlnstest.c | 1 - tests/securityselinuxlabeldata/chardev.xml | 2 +- tests/securityselinuxlabeldata/disks.xml | 2 +- tests/securityselinuxlabeldata/kernel.xml | 2 +- tests/securityselinuxlabeldata/nfs.xml | 2 +- tests/securityselinuxlabeltest.c | 4 +- tests/testutils.c | 8 +- tests/testutilslxc.c | 10 +- tests/testutilsqemu.c | 38 ++-- tests/testutilsxen.c | 18 +- tests/vircapstest.c | 209 +++++++++++++++++- tests/vmx2xmltest.c | 8 +- tests/xlconfigtest.c | 1 - tests/xmconfigtest.c | 1 - tests/xml2sexprtest.c | 1 - tests/xml2vmxtest.c | 9 +- 75 files changed, 742 insertions(+), 756 deletions(-) -- 2.3.5

Adjust qemuDomainObjPrivateFree, qemuDomainObjPrivateXMLFormat, and qemuDomainObjPrivateXMLParse to remove the the iothreadpids usage. Rely on saved domain XML for the 'live' data. - Use vm->def->niothreadids instead of priv->niothreadpids - Remove a couple of (now) unnecessary checks where priv->[n]iothreadpids was referenced. Now we now that at XMLParse we've created the [vm->]def->iothreadids with enough elements to satisfy the maximum of def->iothreads and def->niothreadids, so no need to check if it exists like we had to for priv->iothreadpids Patch 3 (old patch 6) - Remove 'name' from virDomainAddIOThread - Fix comments in virDomainIOThreadAdd and virDomainIOThreadDel - Remove if ((unsigned short) iothread_id != iothread_id) check Patch 4 (old patch 7) - Remove 'name' from remote_domain_add_iothread_args and remote_domain_add_iothread_args Patch 5 (old patch 8) - Split qemuDomainHotplugIOThread into qemuDomainHotplugAddIOThread and qemuDomainHotplugDelIOThread - Removed extraneous comments - Moved active domain check to after job starts and only for LIVE - Removed the virResetLastError if qemuMonitorGetIOThreads fails - Didn't touch the Numatune change - that can be resolved separately - For the Add case, there was a comment about already having the data which while true, we don't know where in the returned qemu iothreads list the new IOThread was added, so we have to find it in the list so we can get the thread_id so save once we create the element in the iothreadids list. - Moved where the virDomainLiveConfigHelperMethod was called - For an inactive config - we can add iothreads and iothreadids, when/if someone starts the guest, then they'll get the bad news if the right emulator wasn't available. - Handling LIVE before CONFIG just seemed to be the norm for commands that I looked at, so I left it that way.

[libvirt] [PATCH] spec: If installing default network, reload libvirtd (bz 867546)
by Cole Robinson 21 Apr '15

21 Apr '15

If libvirt-daemon-config-network is installed while libvirtd is already running, the daemon needs to be restarted to pick up the change. Instead let's trigger a daemon reload when the package is first installed. Then the default network is available immediately if libvirtd was already running. https://bugzilla.redhat.com/show_bug.cgi?id=867546 --- libvirt.spec.in | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/libvirt.spec.in b/libvirt.spec.in index e08c9e7..ada0257 100644 --- a/libvirt.spec.in +++ b/libvirt.spec.in @@ -1770,6 +1770,14 @@ if test $1 -eq 1 && test ! -f %{_sysconfdir}/libvirt/qemu/networks/default.xml ; < %{_datadir}/libvirt/networks/default.xml \ > %{_sysconfdir}/libvirt/qemu/networks/default.xml ln -s ../default.xml %{_sysconfdir}/libvirt/qemu/networks/autostart/default.xml + + # Make sure libvirt picks up the new network defininiton + %if %{with_systemd} + /bin/systemctl reload libvirtd.service >/dev/null 2>&1 ||: + %else + /sbin/service libvirtd reload > /dev/null 2>&1 || : + %endif + fi %endif -- 2.3.5

[libvirt] [PATCH] qemu: Always refresh capabilities if no <guests> found (bz 1000116)
by Cole Robinson 21 Apr '15

21 Apr '15

- Remove all qemu emulators - Restart libvirtd - Install qemu emulators - Call 'virsh version' -> errors The only thing that will force the qemu driver to refresh it's cached capablities info is an explict API call to GetCapabilities. However in the case when the initial caps lookup at driver connect didn't find a single qemu emulator to poll, the driver is effectively useless and really can't do anything until it's populated some qemu capabilities info. With the above steps, the user would have to either know about the magic refresh capabilities call, or restart libvirtd to pick up the changes. Instead, this patch changes things so that every time a part of th driver requests access to capabilities info, check to see if we've previously seen any emulators. If not, force a refresh. In the case of 'still no emulators found', this is still very quick, so I can't think of a downside. https://bugzilla.redhat.com/show_bug.cgi?id=1000116 --- src/qemu/qemu_conf.c | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/src/qemu/qemu_conf.c b/src/qemu/qemu_conf.c index 2cf3905..b662b69 100644 --- a/src/qemu/qemu_conf.c +++ b/src/qemu/qemu_conf.c @@ -965,6 +965,13 @@ virCapsPtr virQEMUDriverGetCapabilities(virQEMUDriverPtr driver, qemuDriverLock(driver); } + if (driver->caps->nguests == 0 && !refresh) { + VIR_DEBUG("Capabilities didn't detect any guests.

[libvirt] [PATCH v4 0/4] storage: handle scsi/iscsi error paths better
by John Ferlan 21 Apr '15

21 Apr '15

v3 here: http://www.redhat.com/archives/libvir-list/2015-April/msg00240.html changes: Patch 1: (prior patch 1) Adjustments from code review - mostly just creating a new function using the "const char *" path instead of pool pointer. Called only from virStorageBackendStablePath Patch 2: (prior patch 3) Rather than continue to try to talk through the v3, here's the latest changes. These will just check in the SCSINewLun if the source pool target path doesn't start with /dev, then to just fail. This includes if the path is "/dev" or "/dev/". Theory for failure is that even if we allowed "/dev" or "/dev/" to continue down into the call to virStorageBackendStablePath all we'd get back was the duplicated 'devpath' which we'd claim was non-fatal. Patch 3: (NEW) Adjust virStorageBackendSCSIFindLUs to return a count of LU's found rather than the current "0" or -1" with a setting of the boolean found (which gets ignored in most cases). By returning a count, 0, or -1 the caller can decide what to do with the data. Patch 4: (prior patch 4) Couple of minor changes regarding comments and the use of a goto instead of if then else in processLU retval checks. Kept the flow as previous including using 'retval' in virStorageBackendSCSIFindLUs rather than creating yet another local status that would need to be checked.

[libvirt] [PATCH 0/2] rework the check for the numa cpus
by Luyao Huang 21 Apr '15

21 Apr '15

We introduce a check for numa cpu total count in 5f7b71, But seems this check cannot work well. There are some scenarioes: 1. one of cpu id is out of maxvcpus, can set success(cpu count = 5 < 10): <vcpu placement='static'>10</vcpu> <cell id='0' cpus='0-3,100' memory='512000' unit='KiB'/> the cpus '100' exceed maxvcpus, this setting is not valid (although qemu do not output error). 2. use the same cpu in 2 cell, can set success(cpu count = 8 < 10): <vcpu placement='static'>10</vcpu> <cell id='0' cpus='0-3' memory='512000' unit='KiB'/> <cell id='1' cpus='0-3' memory='512000' unit='KiB'/> I guess nobody will use this setting if he really want use numa in his vm. (qemu not output error, but we can find some interesting things in vm, all cpus have bind in one numa node) 3. use the same cpu in 2 cell, cannot set success(cpu count = 11 > 10): <vcpu placement='static'>10</vcpu> <cell id='0' cpus='0-6' memory='512000' unit='KiB'/> <cell id='1' cpus='0-3' memory='512000' unit='KiB'/> No need forbid this scenario if scenario 2 is a 'valid' setting. However add new check during parse xml will make vm has broken settings disappear after update libvirtd, so possible solutions: 1. add new check when parse xml, and find a way to avoid vm evaporate. I chose this way and i don't think just drop the invalid settings is a good idea for numa cpus, so i add a new function. 2. add new check when start vm. I think this is a configuration issue, so no need report it so late. 3. just remove this check and do not add new check... :) Luyao Huang (2): conf: introduce a new function to add check avoid losing track conf: rework the cpu check for vm numa settings src/bhyve/bhyve_driver.c | 4 ++-- src/conf/domain_conf.c | 21 ++++++++++++++------- src/conf/domain_conf.h | 1 + src/conf/numa_conf.c | 37 ++++++++++++++++++++++++++++++------- src/conf/numa_conf.h | 2 +- src/esx/esx_driver.c | 2 +- src/libxl/libxl_driver.c | 4 ++-- src/lxc/lxc_driver.c | 4 ++-- src/openvz/openvz_driver.c | 4 ++-- src/parallels/parallels_driver.c | 2 +- src/phyp/phyp_driver.c | 2 +- src/qemu/qemu_driver.c | 4 ++-- src/test/test_driver.c | 4 ++-- src/uml/uml_driver.c | 4 ++-- src/vbox/vbox_common.c | 2 +- src/vmware/vmware_driver.c | 4 ++-- src/xen/xen_driver.c | 4 ++-- src/xenapi/xenapi_driver.c | 4 ++-- 18 files changed, 70 insertions(+), 39 deletions(-) -- 1.8.3.1

[libvirt] [PATCH] qemu: set macvtap physdevs online when macvtap is set online
by Laine Stump 21 Apr '15

21 Apr '15

A further fix for: https://bugzilla.redhat.com/show_bug.cgi?id=1113474 Since there is no possibility that any type of macvtap will work if the parent physdev it's attached to is offline, we should bring the physdev online at the same time as the macvtap. When taking the macvtap offline, it's also necessary to take the physdev offline for macvtap passthrough mode (because the physdev has the same MAC address as the macvtap device, so could potentially cause problems with misdirected packets during migration, as outlined in commits 829770 and 879c13). We can't set the physdev offline for other macvtap modes 1) because there may be other macvtap devices attached to the same physdev in the other modes whereas passthrough mode is exclusive to one macvtap at a time, and 2) there's no practical reason to do so anyway. --- src/qemu/qemu_hotplug.c | 8 +++----- src/qemu/qemu_interface.c | 29 +++++++++++++++++++++++++++-- 2 files changed, 30 insertions(+), 7 deletions(-) diff --git a/src/qemu/qemu_hotplug.c b/src/qemu/qemu_hotplug.c index 2f0549e..9be2ea3 100644 --- a/src/qemu/qemu_hotplug.c +++ b/src/qemu/qemu_hotplug.c @@ -3931,11 +3931,9 @@ qemuDomainDetachNetDevice(virQEMUDriverPtr driver, VIR_WARN("cannot clear bandwidth setting for device : %s", detach->ifname); - /* deactivate the tap/macvtap device on the host (currently this - * isn't necessary, as everything done in - * qemuInterfaceStopDevice() is made meaningless when the device - * is deleted anyway, but in the future it may be important, and - * doesn't hurt anything for now) + /* deactivate the tap/macvtap device on the host, which could also + * affect the parent device (e.g. macvtap passthrough mode sets + * the parent device offline) */ ignore_value(qemuInterfaceStopDevice(detach)); diff --git a/src/qemu/qemu_interface.c b/src/qemu/qemu_interface.c index 201a7dd..01226ac 100644 --- a/src/qemu/qemu_interface.c +++ b/src/qemu/qemu_interface.c @@ -63,7 +63,20 @@ qemuInterfaceStartDevice(virDomainNetDefPtr net) goto cleanup; } break; - case VIR_DOMAIN_NET_TYPE_DIRECT: + + case VIR_DOMAIN_NET_TYPE_DIRECT: { + const char *physdev = virDomainNetGetActualDirectDev(net); + bool isOnline = true; + + /* set the physdev online if necessary.

[libvirt] [PATCH] parallels: make device addressing consistent
by Nikolay Shirokovskiy 20 Apr '15

20 Apr '15

In Parallels we do not support device name hints aka <target dev=../> option and full-fledged device disk device addressing through <address type=.. controller=.. bus=.. target=.. unit=../> and have only one index instead. In this situation to be consistent we can only take one-to-one mapping from some reasonable subset of full address. Values outside this subset are invalid to create Parallels VMs. Reasonable mapping is default one defined in virDomainDiskDefAssignAddress.

[libvirt] [PATCH] domtop: Properly free cpu status
by Michal Privoznik 20 Apr '15

20 Apr '15

So, in the example the cpu stats are collected within a function called do_top. At the beginning of the function we ask the daemon for how much vCPUs can we get stats, and how many stats for a vCPU can we get. This is because it's how our API works - users are required to preallocate a chunk of memory for the results. Now, at the end, we try to free the allocated array, but we are not doing it correctly. There's this virTypedParamsFree() function which gets a pointer to the array and the length of the array. However, if there was an error in getting vCPU stats we pass a negative number instead of the originally computed value. This flaw results in SIGSEGV: libvirt: QEMU Driver error : Requested operation is not valid: domain is not running ERROR do_top:333 : Unable to get cpu stats ==29201== Invalid read of size 4 ==29201== at 0x4F1DF8B: virTypedParamsClear (virtypedparam.c:1145) ==29201== by 0x4F1DFEB: virTypedParamsFree (virtypedparam.c:1165) ==29201== by 0x4023C3: do_top (domtop.c:349) ==29201== by 0x40260B: main (domtop.c:386) ==29201== Address 0x131cd7c0 is 16 bytes after a block of size 768 alloc'd ==29201== at 0x4C2C070: calloc (in /usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so) ==29201== by 0x401FF1: do_top (domtop.c:295) ==29201== by 0x40260B: main (domtop.c:386) Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com> --- examples/domtop/domtop.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/examples/domtop/domtop.c b/examples/domtop/domtop.c index e50988e..2283994 100644 --- a/examples/domtop/domtop.c +++ b/examples/domtop/domtop.c @@ -346,8 +346,8 @@ do_top(virConnectPtr conn, ret = 0; cleanup: - virTypedParamsFree(now_params, now_nparams * max_id); - virTypedParamsFree(then_params, then_nparams * max_id); + virTypedParamsFree(now_params, nparams * max_id); + virTypedParamsFree(then_params, nparams * max_id); if (dom) virDomainFree(dom); return ret; -- 2.0.5

[libvirt] [PATCH 0/5] Add vmport feature (v3)
by Marc-André Lureau 20 Apr '15

20 Apr '15

Hi, The QEMU machine vmport option allows to set the VMWare IO port emulation. This emulation is useful for absolute pointer input when the guest has vmware input drivers, and is enabled by default for kvm. However it is unnecessary for Spice-enabled VM, since the agent already handles absolute pointer and multi-monitors. Furthermore, it prevents Spice from switching to relative input since the regular ps/2 pointer driver is replaced by the vmware driver. It is thus advised to disable vmport when using a Spice VM. This will permit the Spice client to switch from absolute to relative pointer, as it may be required for certain games or applications. The following patch series allows to configure the vmport feature. The first version sent used a domain attribute, Daniel Berrange suggested to use a feature instead. I sent a second version that didn't receive reviews. Hopefully this one will stand more chances! cheers Marc-André Lureau (5): docs: add domain vmport feature domain/conf: add VIR_DOMAIN_FEATURE_VMPORT qemu: add QEMU_CAPS_MACHINE_VMPORT_OPT qemu: add machine vmport argument tests: add machine-vmport-opt qemu test docs/formatdomain.html.in | 6 +++++ docs/schemas/domaincommon.rng | 9 +++++++ src/conf/domain_conf.c | 5 +++- src/conf/domain_conf.h | 1 + src/qemu/qemu_capabilities.c | 6 +++++ src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 14 +++++++++++ .../qemuxml2argv-machine-vmport-opt.args | 6 +++++ .../qemuxml2argv-machine-vmport-opt.xml | 28 ++++++++++++++++++++++ tests/qemuxml2argvtest.c | 2 ++ 10 files changed, 77 insertions(+), 1 deletion(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-machine-vmport-opt.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-machine-vmport-opt.xml -- 2.1.0

[libvirt] Building libvirt under Windows
by Pavel Fedin 20 Apr '15

20 Apr '15

Hello! I am currently building libvirt under Windows64, and i would like to ask for correct way to do it. The first thing to resolve is absence of RPC XDR library. From configure source i figured out that portablexdr library may help. I have downloaded it, but it comes with a different RPC code generator named portable-rpcgen. I managed to use it, but i had to patch both libvirt (in order to recognize this generator and handle it properly) and portable-rpcgen (in order to correctly work under Windows, as well as get rid of some crashes). Initially i wanted to upstream portablexdr fixes and emailed the author. But the author replied that he is not going to fix portablexdr because it's now deprecated, since original XDR code comes under free license now. So, i have all necessary fixes in my own fork. He suggested me to come here to ask about these things. So, guys, how do you do it ? I cannot find any rpcgen package usable under Windows (MinGW, not Cygwin). Kind regards, Pavel Fedin Expert Engineer Samsung Electronics Research center Russia

I did learn last night, the difference between my two systems that is relevant is that the overflow system ran Gentoo while the "working" system ran Debian. I was missing a USE flag for "virt-network" on the Gentoo machine. It is a development environment that I am attempting to create a supported configuration with, so these kinds of missing USE flags and other things are just facts of life I must accept. Unfortunately, it was kind-of difficult to get this information or even workaround it without rebuilding libvirt on the Gentoo machine, which means I won't be able to give a proper error message to users who encounter this problem as well. It's a problem in libvirt-php to overflow when requesting libvirt_networks_list on a machine without networking support compiled in. The PHP bindings should error out properly, not memory overflow and put errors in httpd log with cryptic results in the interpreter :-) I do like the PHP bindings but they appear to be lacking attention. Am I the only one using it? ;-) Kash Pande Jentu Technologies, Inc http://jentu-networks.com

[libvirt] [PATCH v4 0/9] qemu: Add quorum support to libvirt
by Matthias Gatto 20 Apr '15

20 Apr '15

The purpose of these patches is to introduce quorum for libvirt I've try to follow this proposal: http://www.redhat.com/archives/libvir-list/2014-May/msg00533.html This feature ask for 6 task: 1) Allow a _virStorageSource to contain more than one backing store. Because all the actual libvirt code use the backingStore field as a pointer and we needs want to change that, I've decide to encapsulate the backingStore field to simplifie the array manipulation. 2) Add the missing field a quorum need in _virStorageSource and the VIR_STORAGE_TYPE_QUORUM and VIR_STORAGE_FILE_QUORUM in their respectives enums. 3) Parse and format the xml Because a quorum allows to have more than one backing store at the same level we need to change virDomainDiskDefFormat and virDomainDiskDefParseXML to call virDomainDiskBackingStoreFormat and virDomainDiskBackingStoreParse in a loop. virDomainDiskBackingStoreFormat and virDomainDiskBackingStoreParse can call themself recursively in a loop because a quorum can contain another quorum 4) Add nodename We need to add nodename support in _virStorageSource because qemu use them for their child. 5) Build qemu string As for the xml, we have to call the function which create quorum recursively. But this task have the problem explained here: http://www.redhat.com/archives/libvir-list/2014-October/msg00529.html The _virStorageSource missing some informations that can be passed to a child, and therefore this version of quorum is incomplet. 6) Allow to hotplug/change a disk in a quorum This part is not present in these patches because for this task we have to use blockdev-add, and currently libvirt use device_add for hotpluging that doesn't allow to hotplug quorum childs. There is 3 way to handle this problem: 1) create a virDomainBlockDevAdd function in libvirt witch call blockdev-add. 2) use blockdev-add instead of device_add in qemuMonitorJSONAddDevice 3) write a hack which uses blockdev-add when only attaching quorum (but i'm pretty sure this solution is not the good one) V2: -Rebase on master -Add Documentation V3: -Transforme the backingStore field in virStorageSource into an array of pointer instead of a pointer -Modify virStorageSourceSetBackingStore to allow it to expand the backingStore size. V4: -Rebase on master Matthias Gatto (9): virstoragefile: Add virStorageSourceGetBackingStore virstoragefile: Always use virStorageSourceGetBackingStore to get backing store virstoragefile: Add virStorageSourceSetBackingStore virstoragefile: Always use virStorageSourceSetBackingStore to set backing store virstoragefile: change backingStore to backingStores. virstoragefile: Add quorum in virstoragefile domain_conf: Read and Write quorum config qemu: Add quorum support in qemuBuildDriveDevStr virstoragefile: Add node-name docs/formatdomain.html.in | 27 ++++- docs/schemas/domaincommon.rng | 95 +++++++++++------ docs/schemas/storagecommon.rng | 1 + docs/schemas/storagevol.rng | 1 + src/conf/domain_conf.c | 195 ++++++++++++++++++++++++++-------- src/conf/storage_conf.c | 22 ++-- src/libvirt_private.syms | 2 + src/qemu/qemu_cgroup.c | 4 +- src/qemu/qemu_command.c | 114 ++++++++++++++++++++ src/qemu/qemu_domain.c | 2 +- src/qemu/qemu_driver.c | 30 +++--- src/qemu/qemu_migration.c | 1 + src/security/security_dac.c | 2 +- src/security/security_selinux.c | 4 +- src/security/virt-aa-helper.c | 2 +- src/storage/storage_backend.c | 35 +++--- src/storage/storage_backend_fs.c | 37 ++++--- src/storage/storage_backend_gluster.c | 10 +- src/storage/storage_backend_logical.c | 15 ++- src/storage/storage_driver.c | 2 +- src/util/virstoragefile.c | 116 +++++++++++++++++--- src/util/virstoragefile.h | 13 ++- tests/virstoragetest.c | 18 ++-- 23 files changed, 573 insertions(+), 175 deletions(-) -- 1.8.3.1

[libvirt] [PATCH] rng: Forbid to validate mismatched <disk> 'device' and 'type' attributes
by Erik Skultety 20 Apr '15

20 Apr '15

According to docs, using 'lun' as a value for device attribute is only valid with disk types 'block' and 'network'. However current RNG schema also allows a combination type='file' device='lun' which results in a successfull xml validation, but fails at qemuBuildCommandLine. Besides fixing the RNG schema, this patch also adds a qemuxml2argvtest for this case. https://bugzilla.redhat.com/show_bug.cgi?id=1210669 --- docs/schemas/domaincommon.rng | 42 ++++++++++++++-------- .../qemuxml2argv-disk-device-lun-type-invalid.xml | 28 +++++++++++++++ tests/qemuxml2argvtest.c | 2 ++ 3 files changed, 58 insertions(+), 14 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-device-lun-type-invalid.xml diff --git a/docs/schemas/domaincommon.rng b/docs/schemas/domaincommon.rng index 03fd541..ee32b73 100644 --- a/docs/schemas/domaincommon.rng +++ b/docs/schemas/domaincommon.rng @@ -1316,37 +1316,43 @@ </choice> </attribute> </optional> + <interleave> + <ref name="diskSource"/> + <ref name="diskSpecsExtra"/> + </interleave> </group> <group> <attribute name="device"> - <choice> - <value>lun</value> - </choice> + <value>lun</value> </attribute> <optional> <ref name="rawIO"/> </optional> <optional> - <attribute name="sgio"> - <choice> - <value>filtered</value> - <value>unfiltered</value> - </choice> - </attribute> + <ref name="sgIO"/> </optional> + <interleave> + <choice> + <ref name="diskSourceNetwork"/> + <ref name="diskSourceBlock"/> + </choice> + <ref name="diskSpecsExtra"/> + </interleave> </group> </choice> <optional> <ref name="snapshot"/> </optional> - <interleave> - <ref name="diskSource"/> - <ref name="storageSourceExtra"/> - <ref name="diskBackingChain"/> - </interleave> </element> </define> + <define name="diskSpecsExtra"> + <interleave> + <ref name="storageSourceExtra"/> + <ref name="diskBackingChain"/> + </interleave> + </define> + <define name="diskBackingChain"> <choice> <ref name="diskBackingStore"/> @@ -5315,4 +5321,12 @@ <ref name="virYesNo"/> </attribute> </define> + <define name="sgIO"> + <attribute name="sgio"> + <choice> + <value>filtered</value> + <value>unfiltered</value> + </choice> + </attribute> + </define> </grammar> diff --git a/tests/qemuxml2argvdata/qemuxml2argv-disk-device-lun-type-invalid.xml b/tests/qemuxml2argvdata/qemuxml2argv-disk-device-lun-type-invalid.xml new file mode 100644 index 0000000..ed3c89e --- /dev/null +++ b/tests/qemuxml2argvdata/qemuxml2argv-disk-device-lun-type-invalid.xml @@ -0,0 +1,28 @@ +<domain type='qemu'> + <name>QEMUGuest1</name> + <uuid>c7a5fdbd-edaf-9455-926a-d65c16db1809</uuid> + <memory unit='KiB'>219100</memory> + <currentMemory unit='KiB'>219100</currentMemory> + <vcpu placement='static'>1</vcpu> + <os> + <type arch='i686' machine='pc'>hvm</type> + <boot dev='hd'/> + </os> + <clock offset='utc'/> + <on_poweroff>destroy</on_poweroff> + <on_reboot>restart</on_reboot> + <on_crash>destroy</on_crash> + <devices> + <emulator>/usr/bin/qemu</emulator> + <disk type='file' device='lun' rawio='yes'> + <driver name='qemu' type='qcow2'/> + <source file='/dev/HostVG/QEMUGuest1'/> + <target dev='vda' bus='virtio'/> + <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> + </disk> + <controller type='usb' index='0'/> + <controller type='ide' index='0'/> + <controller type='pci' index='0' model='pci-root'/> + <memballoon model='virtio'/> + </devices> +</domain> diff --git a/tests/qemuxml2argvtest.c b/tests/qemuxml2argvtest.c index 8d0a4aa..63bf6ff 100644 --- a/tests/qemuxml2argvtest.c +++ b/tests/qemuxml2argvtest.c @@ -817,6 +817,8 @@ mymain(void) QEMU_CAPS_DRIVE, QEMU_CAPS_DRIVE_FORMAT); DO_TEST("disk-drive-no-boot", QEMU_CAPS_DRIVE, QEMU_CAPS_DEVICE, QEMU_CAPS_BOOTINDEX); + DO_TEST_FAILURE("disk-device-lun-type-invalid", + QEMU_CAPS_DRIVE, QEMU_CAPS_DEVICE, QEMU_CAPS_VIRTIO_SCSI); DO_TEST("disk-usb", NONE); DO_TEST("disk-usb-device", QEMU_CAPS_DRIVE, QEMU_CAPS_DEVICE, QEMU_CAPS_DEVICE_USB_STORAGE, -- 1.9.3

[libvirt] [PATCH] qemu: lifecycle: guest get rebooted after reboot and shutdown
by zhang bo 20 Apr '15

20 Apr '15

Steps: 1 virsh reboot guest1 --mode=acpi 2 virsh shutdown guest1 --mode=agent Expected result: As the SHUTDOWN job is after REBOOT, we expected the guest to be *shutoff*. Exacted result: After the 2 steps above, the guest got *rebooted*. The reason to this problem: 1 in qemuDomainReboot(mode acpi), it sets priv->fakeReboot to 1. 2 after shutdown/reboot, qemu monitor IO trigged qemuProcessHandleShutdown(), which finds that priv->fakeReboot is 1, and reboot the guest. Root Cause of the problem: After further look into the problem, We found that the design of acpi/agent shutdown/reboot seems a little chaotic. ----------------------------------- sheet1 who sets fakeReboot ----------------------------------- shutdown reboot acpi Y(0) Y(1) agent N N It's apparently, *acpi-mode* jobs set fakeReboot. ----------------------------------- sheet2 who needs to check fakeReboot(qemuProcessHandleShutdown()) ----------------------------------- shutdown reboot acpi Y Y agent *Y* *N* Things become a little odd here. only agent-mode reboot doesn't check fakeReboot. We can tell from the above 2 sheets, that they're not consistent. *Agent-mode shutdown checks fakeReboot(trigger by SHUTDOWN monitorIO event), while it didn't set it before.* The chaos is not caused by libvirtd, it's a systematic problem, including guest os and qemu. (guest os writes ACPI, triggers qemu, qemu then triggers libvirtd) Solution: A simple solution is to make the 1st sheet consistent to the 2nd sheet, which is: ----------------------------------- sheet3 who should set fakeReboot: ----------------------------------- shutdown reboot acpi Y(0) Y(1) agent *Y(0)* N ----------------------------------- we let agent-mode shutdown set fakeReboot to 0.

[libvirt] Selective block device migration implementation
by Pavel Boldin 18 Apr '15

18 Apr '15

Dear Libvirt Developers, I'm working to implement feature request [1]. The feature request proposes to enhance `libvirt' code so the API caller can specify which block devices are to be migrated using e.g. parameters in the `virDomainMigrateToURI3' call. There is the following issues: 1. It is obvious to identify devices to be migrated using the `device_name'. However, these need to be serialized in either 1) a comma-separated string or in 2) a set of values named like `blockdevice%d' with `blockdevice' value holding amount of block devices to migrate. What is the desired approach here? Can block device name contain commas or should I neglect this possibility? 2. `libvirt' behavior in block devices migration was copied from the `QEMU' implementation that ignores read-only devices as well. So, `libvirt' code will need to pass this list to `QEMU' `migrate' QMP command and this argument should be implemented in the `QEMU'. Is there any implementation advices from your side?

If we find that the /dev/* is not in use for the pool, then force an error earlier. This makes the check later on not need to compare the returned path to the generated 'devpath' to compensate for the logic in virStorageBackendStablePath which will strdup the incoming target path if something goes wrong in looking up the directory. Since both paths will use the new virStorageBackendPoolUseDevPath slightly differently, if devpath is the same as vol->target.path, then we know it's not because the pool target path was to blame. Patch 4 - Is the former patch 5, but now since patch 3 returns a failure in virStorageBackendSCSINewLun for that bad path, we can use it to be the error arbiter and bug fixer. Former patch 6 - no longer necessary, although it would circumvent any of the above patches being necessary to solve the bug...

[libvirt] [PATCH] libxl: include a XLU_Config in _libxlDriverConfig
by Olaf Hering 17 Apr '15

17 Apr '15

Upcoming changes for vscsi will use libxlutil.so to prepare the configuration for libxl. The helpers needs a xlu struct for logging. Provide one and reuse the existing output as log target.

[libvirt] [PATCH] domcaps: Check for architecture more wisely
by Michal Privoznik 17 Apr '15

17 Apr '15

https://bugzilla.redhat.com/show_bug.cgi?id=1209948 So we have this bug. The virConnectGetDomainCapabilities() API performs a couple of checks before it produces any result. One of the checks is if the architecture requested by user can be run by the binary (again user provided). However, the check is pretty dumb. It merely compares if the default binary architecture matches the one provided by user. However, a qemu binary can run multiple architectures. For instance: qemu-system-ppc64 can run: ppc, ppcle, ppc64, ppc64le and ppcemb. The default is ppc64, so if user requested something else, like ppc64le, the check would have failed without obvious reason.

[libvirt] libvirtd live-locking on CTX_LOCK when doing 'virsh <domid> save /tmp/blah' with guest corrupting memory (on purpose).
by Konrad Rzeszutek Wilk 17 Apr '15

17 Apr '15

Hey Jim, Andrew, and Ian, This is libvirt v1.2.14 + three patches: c82a59b libxl: drop virDomainObj lock when destroying a domain a1c9d30 libxl: acquire a job when destroying a domain 5bd5406 libxl: Move job acquisition in libxlDomainStart to callers For fun I've set up an guest with PCI passthrough and tried to save it (HAHAH) with an disastrous result (xc_save_helper was stuck). Probably due to outstanding DMA operations wreaking havoc. I will shortly send an patch to disallow 'save' with hosted devices but this scenario exposed an interesting livelock that can happen without passthrough if things go wrong. I have not dug entirely in the code so my observation and theory are most likely incorrect. CC-ing Ian and Andrew. The full dump is below, the end result is that libvirtd is locked. Doing 'libvirt list' or any other commands ends with such command hanged. libvirtd itself locks to be deadlocked on CTX_LOCK. On one thread it has received an event (libxl_osevent_occurred_fd) and tries to take the CTX_LOCK, while another thread (number 10) is stuck in eventloop_iteration which holds the CTX_LOCK. It looks like thread #10 is blocking in libxl_read_exactly waiting for 'libxl-save-helper'. Said application (see below) has dispatched an message through helper_getreply and is blocking on __read_nocancel. I presume the message it has dispatched is the same message the 'libxl_osevent_occurred_fd' is trying to get. In other words, one thread has taken the lock, and is blocked waiting for 'libxl-save-helper'. While 'libxl-save-helper' is blocked waiting for its message to be replied to - which another libvirtd thread tries to do but it cannot as the lock has been already taken. Since I did not dig completely in the code I am probably very wrong about this. Would appreciate thoughts whether this is possible and where I've gotten it wrong. Sorry about the control characters and such.

[libvirt] util: log: How about online change logLevel?
by zhang bo 17 Apr '15

17 Apr '15

Sometimes, when we encounter with a problem, we need to set libvirtd log level to DEBUG to dig detailed information. But changing log level requires us to *restart* libvirtd. 1) #vim /etc/libvirt/libvirtd.conf log_level = 1 2) *service libvirtd restart* We think that it makes sense to develop an API to *online* change log level, without restarting libvirtd. What's your opinion? If it's necessary, I'd like to post a patch here.

[libvirt] request for backwards compatibility
by Kash Pande 17 Apr '15

17 Apr '15

Hi there, I've been trying to use libvirt-php to bring libvirt support to jentu which runs on mostly Debian Wheezy machines. I've had a few bugs setting network devices as active with the released (0.4.8) version: PHP Warning: libvirt_network_get_information(): Invalid XPath node for network gateway IP address in /var/www/libjentu-virt.php on line 54 PHP Warning: libvirt_network_set_active() expects exactly 2 parameters, 1 given in /var/www/libjentu-virt.php on line 55 PHP Warning: libvirt_network_set_active(): Invalid arguments in /var/www/libjentu-virt.php on line 55 Building the latest Git repository results in: gcc -g -O2 -Wall -fpic -DCOMPILE_DL_LIBVIRT=1 -I/usr/include/php5 -I/usr/include/php5/main -I/usr/include/php5/TSRM -I/usr/include/php5/Zend -I/usr/include/php5/ext -I/usr/include/php5/ext/date/lib -c -o libvirt-php.o libvirt-php.c -I/usr/include/libxml2 -DHAVE_CONFIG_H libvirt-php.c: In function ‘zm_startup_libvirt’: libvirt-php.c:1179:2: error: ‘VIR_DOMAIN_VCPU_GUEST’ undeclared (first use in this function) libvirt-php.c:1179:2: note: each undeclared identifier is reported only once for each function it appears in libvirt-php.c: In function ‘get_next_free_numeric_value’: libvirt-php.c:2719:6: warning: format ‘%x’ expects argument of type ‘unsigned int *’, but argument 3 has type ‘long int *’ [-Wformat] make[2]: *** [build] Error 1 And this is because debian wheezy has an old version of libvirt that does not have this declared. The proper solution looks like it'd be a configure-time check and enable or disable the new VCPU guest modifiers if they are not available because I'm not so sure wheezy will ever get a newer version of libvirt. Thanks, Kash Pande Jentu Technologies, Inc. http://jentu-networks.com

[libvirt] [PATCH 0/5] libxl: improve xl config parsing
by Jim Fehlig 17 Apr '15

17 Apr '15

This series was inspired by Marek's and Chunyan's patches to add support for <kernel>, <initrd>, and <cmdline> in Xen HVM domain config https://www.redhat.com/archives/libvir-list/2015-March/msg00328.html https://www.redhat.com/archives/libvir-list/2014-September/msg01006.html Patches 1 and 2 are trivial prep for patch 3, which moves parsing and formatting of <os> config out of the common code and into the xl and xm specfic parsing/formatting code. For ease of review, identical copies of xen{Parse,Format}OS are made in xen_{xl,xm}.c. Changes to the xl parsing/formatting functions are made in patch 4 and 5.

[libvirt] [PATCH] util: set MAC address for VF via netlink message to PF + VF# when possible
by Laine Stump 16 Apr '15

16 Apr '15

Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1113474 When we set the MAC address of a network device as a part of setting up macvtap "passthrough" mode (where the domain has an emulated netdev connected to a host macvtap device that has exclusive use of the physical device, and sets the device MAC address to match its own, i.e. "<interface type='direct'> <source mode='passthrough' .../>"), we use ioctl(SIOCSIFHWADDR) giving it the name of that device. This is true even if it is an SRIOV Virtual Function (VF). But, when we are setting the MAC address / vlan ID of a VF in preparation for "hostdev network" passthrough (this is where we set the MAC address and vlan id of the VF before detaching the host net driver and assigning the device to the domain with PCI passthrough, i.e. "<interface type='hostdev'>", we do the setting via a netlink RTM_SETLINK message for that VF's Physical Function (PF), telling it the VF# we want to change. This sets an "administratively changed MAC" flag for that VF in the PF's driver, and from that point on (until the PF's driver is reloaded) that VF's MAC address can't be changed. This means that if a VF is used for hostdev passthrough, it will have the admin flag set, and future attempts to use that VF for macvtap passthrough will fail. The solution to this problem is to check if a device being used for macvtap passthrough is actually a VF; if so, we use the netlink RTM_SETLINK message to the PF to set the VF's mac address instead of ioctl(SIOCSIFHWADDR); if not, behavior does not change from previously. There are three pieces to making this work: 1) virNetDevMacVLan(Create|Delete)WithVPortProfile() now call virNetDev(Replace|Restore)NetConfig() rather than virNetDev(Replace|Restore)MacAddress() (simply passing -1 for VF# and vlanid). 2) virNetDev(Replace|Restore)NetConfig() check to see if the device is a VF. If so, they find the PF's name and VF#, allowing them to call virNetDev(Replace|Restore)VfConfig(). 3) To prevent mixups when detaching a macvtap passthrough device that had been attached while running an older version of libvirt, virNetDevRestoreVfConfig() is potentially given the preserved name of the VF, and if the proper statefile for a VF can't be found in the stateDir (${stateDir}/${pfname}_vf${vfid}), virNetDevRestoreMacAddress() is called instead (which will look in the file named ${stateDir}/${vfname}). This problem has existed in every version of libvirt that has both macvtap passthrough and interface type='hostdev'. Fortunately people seem to use one or the other though. --- (I'm still doing some testing on this, but as long as this approach doesn't cause any other regressions (so far it doesn't appear to), this is the final form. So any ACK given will be contingent on the functional tests passing.) src/util/virnetdev.c | 66 ++++++++++++++++++++++++++++++++++++++++----- src/util/virnetdevmacvlan.c | 4 +-- 2 files changed, 62 insertions(+), 8 deletions(-) diff --git a/src/util/virnetdev.c b/src/util/virnetdev.c index a7903c3..a3f302f 100644 --- a/src/util/virnetdev.c +++ b/src/util/virnetdev.c @@ -2243,7 +2243,8 @@ virNetDevReplaceVfConfig(const char *pflinkdev, int vf, } static int -virNetDevRestoreVfConfig(const char *pflinkdev, int vf, +virNetDevRestoreVfConfig(const char *pflinkdev, + int vf, const char *vflinkdev, const char *stateDir) { int rc = -1; @@ -2258,6 +2259,17 @@ virNetDevRestoreVfConfig(const char *pflinkdev, int vf, stateDir, pflinkdev, vf) < 0) return rc; + if (vflinkdev && !virFileExists(path)) { + /* this VF's config may have been stored with + * virNetDevReplaceMacAddress while running an older version + * of libvirt.

[libvirt] [PATCH] nwfilter: Partly initialize driver even for non-privileged users
by Michal Privoznik 16 Apr '15

16 Apr '15

https://bugzilla.redhat.com/show_bug.cgi?id=1211436 This reverts commit b7829f959b33c6e32422222a9ed745c0da7dc696. The previous fix was not correct. Like everywhere else, a driver is a global variable allocated in stateInitialize function (or something similar for stateless drivers). Later, when a driver API is called, it's possible that the global variable is accessed and dereferenced. Now, some drivers require root privileges because they undertake some actions reserved only for the system admin (e.g. manipulating host firewall). And here's the trouble, the NWFilter state initializer exited too early when finding out it's running unprivileged, leaving the global NWFilter driver variable uninitialized. Any subsequent API call that tried to lock the driver resulted in dereferencing the driver and thus crash. On the other hand, in order to not resurrect the bug the original commit was fixing, Let's forbid the nwfilter define in session mode.

There is a possibility that we jump onto error label with @lockpath still initialized to NULL. Here, the @lockpath should be unlink()-ed, but passing there a NULL is not a good idea. Don't do that.

[libvirt] unclear docs about scsi hostdev
by Olaf Hering 16 Apr '15

16 Apr '15

The scsi host example in https://libvirt.org/formatdomain.html does not make it clear what "<adapter name='scsi_host0'/>" refers to. It implies that any host #0 will be used. Since the index numbers for each host are dynamic an unexpected device may be used by libvirt. The reason I'm looking at this is to support vscsi in libxl. I have a change for xl(1) and want to add also libvirt support. The xend vscsi driver supported both H:C:T:L and /dev/whatever notation to describe the physical dom0 device. This was translated into H:C:T:L for the xenlinux backend driver. The new pvops backend driver understands "naa.wwn:lun" and "H:C:T:L" format. My libxl implementation will also translate /dev/whatever into "naa.wwn:lun". My change supports both xenlinux and pvops. I think its natural to refer to a /dev/disk/by-*/* name for pdev, if the SCSI device supports that. Looks like _virDomainHostdevSubsysSCSI->u.host is very limited in what it accepts as input. What should be done to accept both "/dev/whatever" and "naa.wwn:lun" as pdev? The <address/> part looks like the same format what the frontend driver understands: "host:channel:target:lun". Olaf

[libvirt] [PATCHv3] qemu: monitor: Refactor and fix monitor checking

Among all the monitor APIs some where checking if mon is NULL and some were not. Since it's possible to have mon equal to NULL in case a second call is attempted once entered the monitor. This requires that every single API checks for the monitor.

[libvirt] building xen and libvirt with odd --prefix fails
by Olaf Hering 16 Apr '15

16 Apr '15

My xen is configured with "--prefix=/odd/path --enable-rpath". My libvirt is configured with "env PKG_CONFIG_PATH=/odd/path/share/pkgconfig bash -x autogen.sh --without-xen --with-libxl". Now make in libvirt fails to find "xen/xen.h" needed by xenconfig/xen_common.c, I think it expects it in /usr/include. But I have no xen-devel.rpm installed. I wonder if there are wrong assumptions in libvirt about xen. Since a while xen has a xenlight.pc which contains the required info to find headers and libs. Can there ever be a case where libxl is somewhere else than libxenstore and whatever else is provided by xen? I think they always go into the very same place. So shouldnt libvirt be updated to first check for xenlight.pc, and use the result for everything related to xen? I think that would work for every xen version which has a xenlight.pc (4.5+). And initially I did not pass the matching --prefix to libvirts configure. Even with matching --prefix libvirt does not look in $prefix/include for xen/xen.h, even with --includedir=$prefix/include.

[libvirt] [PATCHv2] virBitmap: Place virBitmapIsAllClear check after virBitmapParse calls
by Erik Skultety 16 Apr '15

16 Apr '15

This patch adds checks for empty bitmaps right after the calls of virBitmapParse. These only include spots where set API's are called and where domain's XML is parsed. Also, it partially reverts commit 983f5a which added a check for invalid nodeset "0,^0" into virBitmapParse function. This change broke the logic, as an empty bitmap should not cause an error. https://bugzilla.redhat.com/show_bug.cgi?id=1210545 --- src/conf/domain_conf.c | 35 +++++++++++++++++++++++++++++++---- src/conf/numa_conf.c | 23 +++++++++++++++++++---- src/qemu/qemu_driver.c | 5 +++-- src/util/virbitmap.c | 3 --- src/xenconfig/xen_sxpr.c | 7 +++++++ tests/virbitmaptest.c | 13 ++++++++++--- 6 files changed, 70 insertions(+), 16 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 823e003..f7f68ba 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -11577,6 +11577,12 @@ virDomainMemorySourceDefParseXML(xmlNodePtr node, if (virBitmapParse(nodemask, 0, &def->sourceNodes, VIR_DOMAIN_CPUMASK_LEN) < 0) goto cleanup;

[libvirt] qemu: lifecycle: reboot + shutdown, unexpected vm status.
by zhang bo 16 Apr '15

16 Apr '15

Steps: 1 virsh reboot guest1 --mode=acpi 2 virsh shutdown guest1 --mode=agent Expected result: As the SHUTDOWN job is after REBOOT, we expected the guest to be *shutoff*. (Do you think so?) Exacted result: After the 2 steps above, the guest got *rebooted*. The reason to this problem: 1 in qemuDomainReboot(mode acpi), it sets priv->fakeReboot to 1. 2 after shutdown/reboot, qemu monitor IO trigged qemuProcessHandleShutdown(), which finds that priv->fakeReboot is 1, and reboot the guest. Root Cause of the problem: After further look into the problem, We found that the design of acpi/agent shutdown/reboot seems a little chaotic. ----------------------------------- sheet1 who sets fakeReboot ----------------------------------- shutdown reboot acpi Y(0) Y(1) agent N N It's apparently, *acpi-mode* jobs set fakeReboot. ----------------------------------- sheet2 who needs to check fakeReboot(qemuProcessHandleShutdown()) ----------------------------------- shutdown reboot acpi Y Y agent *Y* *N* Things become a little odd here. only agent-mode reboot doesn't check fakeReboot. We can tell from the above 2 sheets, that they're not consistent. *Agent-mode shutdown needs to check fakeReboot(trigger by SHUTDOWN monitorIO event), while it didn't set it before.* The chaos is not caused by libvirtd, it's a systematic problem, including guest os and qemu. (guest os writes ACPI, triggers qemu, qemu then triggers libvirtd) My Solution: A simple solution is to make the 1st sheet consistent to the 2nd sheet, which is: ----------------------------------- sheet3 who should set fakeReboot: ----------------------------------- shutdown reboot acpi Y(0) Y(1) agent *Y(0)* N ----------------------------------- we let agent-mode shutdown set fakeReboot to 0. -------------------------------------------------------------------------------- diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 7eb5a7d..c751dcf 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -1959,6 +1959,8 @@ static int qemuDomainShutdownFlags(virDomainPtr dom, unsigned int flags) goto endjob; } + qemuDomainSetFakeReboot(driver, vm, isReboot); + if (useAgent) { qemuDomainObjEnterAgent(vm); ret = qemuAgentShutdown(priv->agent, agentFlag); @@ -1970,7 +1972,6 @@ static int qemuDomainShutdownFlags(virDomainPtr dom, unsigned int flags) */ if (!useAgent || (ret < 0 && (acpiRequested || !flags))) { - qemuDomainSetFakeReboot(driver, vm, isReboot); /* Even if agent failed, we have to check if guest went away * by itself while our locks were down. */ ---------------------------------------------------------------------------------- Discussion: Although the solution above seems to have solved the problem, but it seems a little awkward to have sheets like this. Maybe we should let sheet2 consistent with sheet1, rather than letting sheet1 consistent to sheet2. But It's too difficult to realize that, seems impossible So, is there a better way to solve this problem? or, shall I commit this patch?

[libvirt] util: client: shall libvirtd record task histories?
by zhang bo 16 Apr '15

16 Apr '15

We recently encountered a problem: 1) migrate a domain 2) the client unexpectedly got *crashed* (let's take it as virsh command) 3) *libvirtd still kept migrating the domain* 4) after it's restarted, the client didn't know the guest is still migrating. The problem is that libvirtd and the client has different view of the task state. After migration, the client may wrongly think that something's wrong that the domain got unexpectedly migrated. In my opinion, libvirtd should just *execute* tasks, like the hands of a human, while clients should be the brain to *schedule and remember* tasks. So, In order to avoid this problem,we should let the client record all the taskes somewhere, and reload the states after its restart. the client may cancel or continue the task as it wishes. Libvirtd should not record the task status. What's your opinions? thanks in advance.

Rather than erroring out make the best attempt to retrieve other data if disks are inaccessible or missing. The failure will still be logged though. Since the bulk stats API is called on multiple domains an error like this makes the API unusable.

[libvirt] [PATCH] virNetSocketNewConnectUNIX: Use flocks when spawning a daemon
by Michal Privoznik 15 Apr '15

15 Apr '15

https://bugzilla.redhat.com/show_bug.cgi?id=1200149 Even though we have a mutex mechanism so that two clients don't spawn two daemons, it's not strong enough. It can happen that while one client is spawning the daemon, the other one fails to connect. Basically two possible errors can happen: error: Failed to connect socket to '/home/mprivozn/.cache/libvirt/libvirt-sock': Connection refused or: error: Failed to connect socket to '/home/mprivozn/.cache/libvirt/libvirt-sock': No such file or directory The problem in both cases is, the daemon is only starting up, while we are trying to connect (and fail). We should postpone the connecting phase until the daemon is started (by the other thread that is spawning it). In order to do that, create a file lock 'libvirt-lock' in the directory where session daemon would create its socket. So even when called from multiple processes, spawning a daemon will serialize on the file lock. So only the first to come will spawn the daemon.

[libvirt] [PATCH v2] Link libvirt_util with datatypes
by Martin Kletzander 15 Apr '15

15 Apr '15

Most of the types in datatypes.[hc] depend on virObject and virClass, but they were specified separatedly from that. We were lucky enough for this to work because wherever the datatypes files were used, that file (binary/shared object) was linked to libvirt_util as well. Fixing this comes up as a pretty nice cleanup.

[libvirt] [PATCH] virsh: fix regression in 'virsh event' by domain
by Eric Blake 15 Apr '15

15 Apr '15

Commit a0670ae caused a regression in 'virsh event' and 'virsh qemu-monitor-event' - if a user tries to filter the command to a specific domain, an error message is printed: $ virsh event dom --loop error: internal error: virsh qemu-monitor-event: no domain VSH_OT_DATA option and then the command continues as though no domain had been supplied (giving events for ALL domains, instead of the requested one). This is because the code was incorrectly assuming that all "domain" options would be supplied via a mandatory VSH_OT_DATA, even though "domain" is optional for these two commands, so we had changed them to VSH_OT_STRING to quit failing for other reasons (ever since it was decided that VSH_OT_DATA and VSH_OT_STRING should no longer be synonyms). In looking at the situation, though, the code for looking up a domain was making a pointless check for whether the option exists prior to finding the option's string value, as vshCommandOptStringReq does just fine at reporting any errors when looking up a string whether or not the option was present. So this is a case of regression fixing by pure code deletion :) * tools/virsh-domain.c (vshCommandOptDomainBy): Drop useless filter. * tools/virsh-interface.c (vshCommandOptInterfaceBy): Likewise. * tools/virsh-network.c (vshCommandOptNetworkBy): Likewise. * tools/virsh-nwfilter.c (vshCommandOptNWFilterBy): Likewise. * tools/virsh-secret.c (vshCommandOptSecret): Likewise. * tools/virsh.h (vshCmdHasOption): Drop unused function. * tools/virsh.c (vshCmdHasOption): Likewise.

[libvirt] macvtap - no incoming ipv6 traffic processed on kvm host unless i start tcpdump on interface
by Stefan Bauer 15 Apr '15

15 Apr '15

Dear folks, I'm using for the first time macvtap interface for my virtual machines in bridged mode. VM -> HOST -> Router -> INTERNET This works fine for ipv4 connectivity. For ipv6 my virtual machines receive appropriate v6 address from radvd but are not able to receive answer packages from outside (ping -t -6 google.de was started inside VM). I see the ping request/response on my router: 14:10:52.147834 IP6 2a01:198:200:8350:dc8b:cd82:144e:14eb > 2a00:1450:4001:806::1018: ICMP6, echo request, seq 108, length 40 14:10:52.182073 IP6 2a00:1450:4001:806::1018 > 2a01:198:200:8350:dc8b:cd82:144e:14eb: ICMP6, echo reply, seq 108, length 40 14:10:55.179874 IP6 2a01:198:200:350::2 > 2a00:1450:4001:806::1018: ICMP6, destination unreachable, unreachable address 2a01:198:200:8350:dc8b:cd82:144e:14eb, length 88 But i do not receive the reply on the VM.

[libvirt] [PATCH 0/9] Duplicate storage pool source refactoring and checks
by John Ferlan 15 Apr '15

15 Apr '15

A precursor to some changes I'm working on - I figured it was better not to hoard the patches and then drop a 15 patch series... Anyway, patches 1-4 refactor the iSCSI <source> duplicate checks into a separate subroutine. While I was at it, I realized the Host checks are duplicate of the NETFS check - so I further separated things out. As I was looking at other possible defs I realized not all of the proposed storage pool defs go through duplicate checks because the switch statement had the 'default:' case - so I removed that, added all the options with the hope that new storage pool types will add their own checking. This left me with a bit of sleuthing for cases I added. I was able to determine that Sheepdog and Gluster both have the possibility of "a" single source host, so I added that check as it doesn't seem like it would be a good idea to have two storage pools looking at the same gluster/sheepdog source For the zfs pool it seems that it's like the DISK, LOGICAL, and FS pools with regard to not having duplicate devices in the pool For mpath there doesn't seem to be any need, but I could be wrong For rbd it wasn't completely clear what to check since multiple hosts are allowed for a single pool - I suppose a proposed definition should check that none of it's definitions match, but then again I'm not clear so I left it alone John Ferlan (9): storage: Refactor iSCSI Source matching storage: Refactor matchISCSISource storage: Invert logic for matchISCSISource storage: Create matchPoolSourceHost storage: Use matchPoolSourceHost for NETFS storage: Remove default from switch in virStoragePoolSourceFindDuplicate storage: Add duplicate host check for Sheepdog pool def storage: Add duplicate host check for Gluster pool def storage: Add duplicate devices check for zfs pool def src/conf/storage_conf.c | 59 +++++++++++++++++++++++++++++++++++-------------- 1 file changed, 43 insertions(+), 16 deletions(-) -- 2.1.0

[libvirt] [PATCH] build: include correct header for time()
by Eric Blake 14 Apr '15

14 Apr '15

Found by ./autobuild.sh during a mingw cross-compile: Commit 8a96e87 was not innocuous - glibc happens to leak the definition of time() through other headers, so that even without <sys/select.h>, virrandom.c compiled just fine. But on mingw, we were not so lucky; <sys/select.h> was important for its side effect of dragging in <time.h>, and we now have nothing providing the declaration of time(): ../../src/util/virrandom.c: In function 'virRandomOnceInit': ../../src/util/virrandom.c:65:5: error: implicit declaration of function 'time' [-Werror=implicit-function-declaration] unsigned int seed = time(NULL) ^ getpid(); ^ ../../src/util/virrandom.c:65:5: error: nested extern declaration of 'time' [-Werror=nested-externs] Signed-off-by: Eric Blake <eblake(a)redhat.com> --- Pushing under the build-breaker rule. src/util/virrandom.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/src/util/virrandom.c b/src/util/virrandom.c index 4301f3f..67a8bd0 100644 --- a/src/util/virrandom.c +++ b/src/util/virrandom.c @@ -1,5 +1,5 @@ /* - * Copyright (C) 2012-2014 Red Hat, Inc. + * Copyright (C) 2012-2015 Red Hat, Inc. * * This library is free software; you can redistribute it and/or * modify it under the terms of the GNU Lesser General Public @@ -25,6 +25,7 @@ #include <inttypes.h> #include <math.h> #include <strings.h> +#include <time.h> #include "virrandom.h" #include "virthread.h" -- 2.1.0

[libvirt] [PATCH] qemu: monitor: Add check that monitor is non-null to specific commands
by Peter Krempa 14 Apr '15

14 Apr '15

Our monitor locking and cleanup code is weird as it allows to remove the monitor object pointer while we are in the monitor. Additionally EVERY api is using the vm private data after @vm was unlocked. This leads to an unpleasant situation, where when qemu crashes during a monitor session while a command is executed (and locks are down), the priv->mon pointer gets cleared (@vm is unlocked). The next monitor call then crashes on commands that did not check if the monitor is non-NULL. Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1209813 and few other possible crashes --- Since this is a workaround rather than a proper fix I'd normally not go this way, but untangling the monitor mess won't be easy so I'll fix the symptoms first. src/qemu/qemu_monitor.c | 42 ++++++++++++++++++++++++++++++++++++++++++ src/qemu/qemu_monitor.h | 12 +++++------- 2 files changed, 47 insertions(+), 7 deletions(-) diff --git a/src/qemu/qemu_monitor.c b/src/qemu/qemu_monitor.c index 2b0e1a5..e8403be 100644 --- a/src/qemu/qemu_monitor.c +++ b/src/qemu/qemu_monitor.c @@ -1171,6 +1171,12 @@ qemuMonitorUpdateVideoMemorySize(qemuMonitorPtr mon, int ret = -1; char *path = NULL; + if (!mon) { + virReportError(VIR_ERR_INVALID_ARG, "%s", + _("monitor must not be NULL")); + return -1; + } + if (mon->json) { ret = qemuMonitorFindObjectPath(mon, "/", videoName, &path); if (ret < 0) { @@ -1886,6 +1892,12 @@ qemuMonitorBlockStatsUpdateCapacity(qemuMonitorPtr mon, { VIR_DEBUG("mon=%p, stats=%p, backing=%d", mon, stats, backingChain); + if (!mon) { + virReportError(VIR_ERR_INVALID_ARG, "%s", + _("monitor must not be NULL")); + return -1; + } + if (!mon->json) { virReportError(VIR_ERR_OPERATION_UNSUPPORTED, "%s", _("block capacity/size info requires JSON monitor")); @@ -3246,6 +3258,12 @@ qemuMonitorAddObject(qemuMonitorPtr mon, mon, type, objalias, props); int ret = -1; + if (!mon) { + virReportError(VIR_ERR_INVALID_ARG, "%s", + _("monitor must not be NULL")); + return -1; + } + if (mon->json) { ret = qemuMonitorJSONAddObject(mon, type, objalias, props); } else { @@ -3265,6 +3283,12 @@ qemuMonitorDelObject(qemuMonitorPtr mon, VIR_DEBUG("mon=%p objalias=%s", mon, objalias); int ret = -1; + if (!mon) { + virReportError(VIR_ERR_INVALID_ARG, "%s", + _("monitor must not be NULL")); + return -1; + } + if (mon->json) ret = qemuMonitorJSONDelObject(mon, objalias); else @@ -3453,6 +3477,12 @@ qemuMonitorBlockCommit(qemuMonitorPtr mon, const char *device, "bandwidth=%llu", mon, device, top, base, NULLSTR(backingName), bandwidth); + if (!mon) { + virReportError(VIR_ERR_INVALID_ARG, "%s", + _("monitor must not be NULL")); + return -1; + } + if (mon->json) ret = qemuMonitorJSONBlockCommit(mon, device, top, base, backingName, bandwidth); @@ -3482,6 +3512,12 @@ qemuMonitorDiskNameLookup(qemuMonitorPtr mon, virStorageSourcePtr top, virStorageSourcePtr target) { + if (!mon) { + virReportError(VIR_ERR_INVALID_ARG, "%s", + _("monitor must not be NULL")); + return NULL; + } + if (!mon->json) { virReportError(VIR_ERR_OPERATION_UNSUPPORTED, "%s", _("JSON monitor is required")); @@ -3592,6 +3628,12 @@ qemuMonitorBlockJob(qemuMonitorPtr mon, mon, device, NULLSTR(base), NULLSTR(backingName), bandwidth, mode, modern); + if (!mon) { + virReportError(VIR_ERR_INVALID_ARG, "%s", + _("monitor must not be NULL")); + return -1; + } + if (mon->json) ret = qemuMonitorJSONBlockJob(mon, device, base, backingName, bandwidth, mode, modern); diff --git a/src/qemu/qemu_monitor.h b/src/qemu/qemu_monitor.h index a3514cf..7e62139 100644 --- a/src/qemu/qemu_monitor.h +++ b/src/qemu/qemu_monitor.h @@ -246,7 +246,7 @@ void qemuMonitorSetOptions(qemuMonitorPtr mon, virJSONValuePtr options) int qemuMonitorUpdateVideoMemorySize(qemuMonitorPtr mon, virDomainVideoDefPtr video, const char *videName) - ATTRIBUTE_NONNULL(1) ATTRIBUTE_NONNULL(2) ATTRIBUTE_NONNULL(3); + ATTRIBUTE_NONNULL(2) ATTRIBUTE_NONNULL(3); int qemuMonitorHMPCommandWithFd(qemuMonitorPtr mon, const char *cmd, int scm_fd, @@ -381,7 +381,7 @@ int qemuMonitorGetAllBlockStatsInfo(qemuMonitorPtr mon, int qemuMonitorBlockStatsUpdateCapacity(qemuMonitorPtr mon, virHashTablePtr stats, bool backingChain) - ATTRIBUTE_NONNULL(1) ATTRIBUTE_NONNULL(2); + ATTRIBUTE_NONNULL(2); int qemuMonitorGetBlockExtent(qemuMonitorPtr mon, const char *dev_name, @@ -730,15 +730,13 @@ int qemuMonitorBlockCommit(qemuMonitorPtr mon, const char *base, const char *backingName, unsigned long long bandwidth) - ATTRIBUTE_NONNULL(1) ATTRIBUTE_NONNULL(2) ATTRIBUTE_NONNULL(3) - ATTRIBUTE_NONNULL(4); + ATTRIBUTE_NONNULL(2) ATTRIBUTE_NONNULL(3) ATTRIBUTE_NONNULL(4); bool qemuMonitorSupportsActiveCommit(qemuMonitorPtr mon); char *qemuMonitorDiskNameLookup(qemuMonitorPtr mon, const char *device, virStorageSourcePtr top, virStorageSourcePtr target) - ATTRIBUTE_NONNULL(1) ATTRIBUTE_NONNULL(2) ATTRIBUTE_NONNULL(3) - ATTRIBUTE_NONNULL(4); + ATTRIBUTE_NONNULL(2) ATTRIBUTE_NONNULL(3) ATTRIBUTE_NONNULL(4); int qemuMonitorArbitraryCommand(qemuMonitorPtr mon, const char *cmd, @@ -774,7 +772,7 @@ int qemuMonitorBlockJobInfo(qemuMonitorPtr mon, const char *device, virDomainBlockJobInfoPtr info, unsigned long long *bandwidth) - ATTRIBUTE_NONNULL(1) ATTRIBUTE_NONNULL(2) ATTRIBUTE_NONNULL(3); + ATTRIBUTE_NONNULL(2) ATTRIBUTE_NONNULL(3); int qemuMonitorOpenGraphics(qemuMonitorPtr mon, const char *protocol, -- 2.3.5

[libvirt] [PATCH] sanlock: Use VIR_ERR_RESOURCE_BUSY if sanlock_acquire fails
by Jiri Denemark 14 Apr '15

14 Apr '15

When acquiring resource via sanlock fails, we would report it as VIR_ERR_INTERNAL_ERROR, which is not very friendly to applications using libvirt. Moreover, the lockd driver would report the same failure as VIR_ERR_RESOURCE_BUSY, which looks better. Unfortunately, in sanlock driver we don't really know if acquiring the resource failed because it was already locked or there was another reason behind. But the end result is the same and I think using VIR_ERR_RESOURCE_BUSY reason for all acquire failures is still better than what we have now. https://bugzilla.redhat.com/show_bug.cgi?id=1165119 Signed-off-by: Jiri Denemark <jdenemar(a)redhat.com> --- src/locking/lock_driver_sanlock.c | 2 +- src/util/virerror.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/src/locking/lock_driver_sanlock.c b/src/locking/lock_driver_sanlock.c index dbe79bc..e052875 100644 --- a/src/locking/lock_driver_sanlock.c +++ b/src/locking/lock_driver_sanlock.c @@ -975,7 +975,7 @@ static int virLockManagerSanlockAcquire(virLockManagerPtr lock, priv->res_count, priv->res_args, opt)) < 0) { if (rv <= -200) - virReportError(VIR_ERR_INTERNAL_ERROR, + virReportError(VIR_ERR_RESOURCE_BUSY, _("Failed to acquire lock: error %d"), rv); else virReportSystemError(-rv, "%s", diff --git a/src/util/virerror.c b/src/util/virerror.c index c4e84e7..91c8686 100644 --- a/src/util/virerror.c +++ b/src/util/virerror.c @@ -1326,7 +1326,7 @@ virErrorMsg(virErrorNumber error, const char *info) if (info == NULL) errmsg = _("resource busy"); else - errmsg = _("resource busy %s"); + errmsg = _("resource busy: %s"); break; case VIR_ERR_ACCESS_DENIED: if (info == NULL) -- 2.3.5

[libvirt] [PATCH] hostdev: fix loop index error when resetvfnetconfig
by Huanle Han 14 Apr '15

14 Apr '15

The variable 'last_processed_hostdev_vf' indicates index of the last successfully configed vf. When resetvfnetconfig because of failure, hostdevs[last_processed_hostdev_vf] should also be reset.

[libvirt] [PATCH] qemu: fix index error when clean up vport profile
by Huanle Han 14 Apr '15

14 Apr '15

1. 'last_good_net' indicates the index of last successfully configured net. so def->nets[last_good_net] should also be clean up if error occurs. 2. if error occurs in 'virNetDevMacVLanVPortProfileRegisterCallback' (second 'goto err_exit' in loop), we should also do 'virNetDevVPortProfileDisassociate' cleanup for the 'virNetDevVPortProfileAssociate'(first code block in loop). So we should consider the net is successfully configured after first code block in loop finishes.
