[libvirt] [PATCH 0/2] CPU Probing Revisited
by Viktor Mihajlovski 04 Dec '12

04 Dec '12

I have not yet given up on the CPU probing. Since the orginal patch was not well received w.r.t error checking I have effectively undone the cpu model checking part. Next, I have enabled the QMP query-cpu-definitions command in a minimalistic fashion, return host as the only supported CPU model. The patch works in so far that I can see the result flowing back to libvirt. Unfortunately libvirt seems to choke on what it gets, but I will follow up on this seperately, probably just another libvirt QMP hickup... Viktor Mihajlovski (2): S390: Undo the cpu model checking.

[libvirt] [PATCH 00/10 v4] Unprivileged SG_IO support
by Osier Yang 04 Dec '12

04 Dec '12

Hi, As a result of RFC [1], this implements the unprivleged SG_IO support. Testing is not that enough, but I'd like see the reviewing earlier, and meanwhile I'm not going to give up the further testing. v2 - v3: * Change the XML tag name to "cdbfilter" * Maintain an internal list of shared disks for QEMU driver. v3 - v4: * Rebase on the top * More testing Patches 1/10 ~ 4/10 are to introduce the internal list for shared disks. Osier Yang (10): qemu: Introduce a list to maintain the shared disks between domains qemu: Init/Free the list with the driver's lifecyle qemu: Add/remove the shared disk entry during domain's lifecyle qemu: Add/Remove the entry of sharedDisks when live attaching/detaching docs: Add docs and rng schema for new XML cdbfilter conf: Parse and format the new XML tag cdbfilter util: Prepare helpers for unpriv_sgio setting qemu: Manage disk's cdbfilter in domain's lifecycle qemu: Do not restore the sysfs unpriv_sgio if the disk is being shared qemu: Error out when domain starting if the cdbfilter setting conflicts Regards, Osier

[libvirt] [PATCH V2] implement managedsave in libvirt xen legacy driver
by Bamvor Jian Zhang 04 Dec '12

04 Dec '12

Implement the domainManagedSave, domainHasManagedSaveImage, and domainManagedSaveRemove functions in the libvirt legacy xen driver. domainHasManagedSaveImage check the managedsave image from filesystem everytime. This is different from qemu and libxl driver. In qemu or libxl driver, there is a hasManagesSave flags in virDomainObjPtr which is not used in xen legacy driver. This flag could not add into xen driver ptr either, because the driver ptr will be release at the end of every libvirt api calls. Meanwhile, AFAIK, xen store all the flags in xen not in libvirt xen driver. There is no need to add this flags in xen. Signed-off-by: Bamvor Jian Zhang <bjzhang(a)suse.com> --- Changes since v1: (1), add save dir in libvirt.spec.in and src/Makefile.am (2), misc changes for return value and memory leak. i have test the following case for this patch: 1), "virsh managedsave" save domain to /var/lib/xen/save/domain_name.save. call xenUnifiedDomainManagedSave. 2), "virsh start": if managedsave image is exist, it should be boot from managed save image. call xenUnifiedDomainHasManagedSaveImage. 3), "virsh start --force-boot": fresh boot, delete the managed save image if exists. call xenUnifiedDomainHasManagedSaveImage, xenUnifiedDomainManagedSaveRemove. 4), "virsh managedsave-remove": remove managed save image. call xenUnifiedDomainManagedSaveRemove 5), "virsh undefine": undefine the domain, it will fail if mananed save image exist. call xenUnifiedDomainHasManagedSaveImage. 6), "virsh undefine --managed-save": undefine the domain, and remove mananed save image. call xenUnifiedDomainHasManagedSaveImage and xenUnifiedDomainManagedSaveRemove. 7), "virsh list --all --with-managed-save". list domain if managed save image exist. got nothing if non-exists. call xenUnifiedDomainHasManagedSaveImage. 8), "virsh list --all --without-managed-save". do not list the domain if managed save image exist. call xenUnifiedDomainHasManagedSaveImage. libvirt.spec.in | 3 ++ src/Makefile.am | 6 +++ src/xen/xen_driver.c | 108 ++++++++++++++++++++++++++++++++++++++++++++++++++- src/xen/xen_driver.h | 2 + 4 files changed, 118 insertions(+), 1 deletion(-) diff --git a/libvirt.spec.in b/libvirt.spec.in index 47cb087..ae18adb 100644 --- a/libvirt.spec.in +++ b/libvirt.spec.in @@ -1719,6 +1719,9 @@ rm -f $RPM_BUILD_ROOT%{_sysconfdir}/sysctl.d/libvirtd %ghost %dir %{_localstatedir}/run/libvirt/libxl/ %dir %attr(0700, root, root) %{_localstatedir}/lib/libvirt/libxl/ %endif +%if %{with_xen} +%dir %attr(0700, root, root) %{_localstatedir}/lib/libvirt/xen/ +%endif %if %{with_network} %ghost %dir %{_localstatedir}/run/libvirt/network/ %dir %attr(0700, root, root) %{_localstatedir}/lib/libvirt/network/ diff --git a/src/Makefile.am b/src/Makefile.am index 01cb995..fc0d78a 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -1769,6 +1769,9 @@ if WITH_UML $(MKDIR_P) "$(DESTDIR)$(localstatedir)/lib/libvirt/uml" $(MKDIR_P) "$(DESTDIR)$(localstatedir)/run/libvirt/uml" endif +if WITH_XEN + $(MKDIR_P) "$(DESTDIR)$(localstatedir)/lib/libvirt/xen" +endif if WITH_NETWORK $(MKDIR_P) "$(DESTDIR)$(localstatedir)/lib/libvirt/network" $(MKDIR_P) "$(DESTDIR)$(localstatedir)/lib/libvirt/dnsmasq" @@ -1815,6 +1818,9 @@ if WITH_UML rmdir "$(DESTDIR)$(localstatedir)/lib/libvirt/uml" ||: rmdir "$(DESTDIR)$(localstatedir)/run/libvirt/uml" ||: endif +if WITH_XEN + rmdir "$(DESTDIR)$(localstatedir)/lib/libvirt/xen" ||: +endif if WITH_NETWORK rm -f $(DESTDIR)$(sysconfdir)/libvirt/qemu/networks/autostart/default.xml rm -f $(DESTDIR)$(sysconfdir)/libvirt/qemu/networks/default.xml diff --git a/src/xen/xen_driver.c b/src/xen/xen_driver.c index 5a40757..71ff5bd 100644 --- a/src/xen/xen_driver.c +++ b/src/xen/xen_driver.c @@ -65,8 +65,10 @@ #include "command.h" #include "virnodesuspend.h" #include "nodeinfo.h" +#include "configmake.h" #define VIR_FROM_THIS VIR_FROM_XEN +#define XEN_SAVE_DIR LOCALSTATEDIR "/lib/libvirt/xen/save" static int xenUnifiedNodeGetInfo(virConnectPtr conn, virNodeInfoPtr info);

[libvirt] RFC: Coding style: require alphabetical header file sorting
by Daniel P. Berrange 04 Dec '12

04 Dec '12

Thus far we only have one rule about header files, #include <config.h> must be first in all .c files. I'm wondering if it is time to introduce some new rules - All system headers must be grouped to preceed all local headers - All system headers must be sorted within their group - All local headers must be sorted within their group This will require updating pretty much every single source and header file in the tree. Of course it will need a new syntax check rule to validate this too. Since fixing them is a serious amount of work, I was wondering about people's opinions on this ? The goal is just standardization to make code a little more readable.

[libvirt] [PATCH v1 00/11] Allow minimal bandwidth guarantee
by Michal Privoznik 03 Dec '12

03 Dec '12

This is a rework of my one year old patchset [1]. If you are brave enough and start reviewing it, you may want to read the last patch first. The whole magic hidden behind the scene is documented there. For now, the only supported combination where this works is virtual interface connected to virtual network. This network MUST have an inbound average set, at least. This tells how much bandwidth do we have, and how much can we guarantee. If we would miss this info, then we cannot guarantee anything. On the other hand, this is just a very small part of whole problem. Users MUST configure all other devices on traffic path to follow up their setting in libvirt.

[libvirt] libvirt [PATCHv2 2/2] Add iSCSI backend storage driver for ESX.
by Ata E Husain Bohra 03 Dec '12

03 Dec '12

The patch adds the backend driver to support iSCSI format storage pools and volumes for ESX host. The mapping of ESX iSCSI specifics to Libvirt is as follows: 1. ESX static iSCSI target <------> Libvirt Storage Pools 2. ESX iSCSI LUNs <------> Libvirt Storage Volumes. The above understanding is based on http://libvirt.org/storage.html. The operation supported on iSCSI pools includes: 1. List storage pools & volumes. 2. Get xml descriptor operaion on pools & volumes. 3. Lookup operation on pools & volumes by name, uuid and path (if applicable). iSCSI pools does not support operations such as: Create / remove pools and volumes. --- src/Makefile.am | 1 + src/esx/esx_storage_backend_iscsi.c | 807 +++++++++++++++++++++++++++++++++++ src/esx/esx_storage_backend_iscsi.h | 29 ++ src/esx/esx_storage_driver.c | 8 +- src/esx/esx_vi.c | 332 ++++++++++++++ src/esx/esx_vi.h | 18 + src/esx/esx_vi_generator.input | 302 +++++++++++++ src/esx/esx_vi_generator.py | 19 + 8 files changed, 1515 insertions(+), 1 deletion(-) create mode 100644 src/esx/esx_storage_backend_iscsi.c create mode 100644 src/esx/esx_storage_backend_iscsi.h diff --git a/src/Makefile.am b/src/Makefile.am index 4026a15..1668b84 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -494,6 +494,7 @@ ESX_DRIVER_SOURCES = \ esx/esx_network_driver.c esx/esx_network_driver.h \ esx/esx_storage_driver.c esx/esx_storage_driver.h \ esx/esx_storage_backend_vmfs.c esx/esx_storage_backend_vmfs.h \ + esx/esx_storage_backend_iscsi.c esx/esx_storage_backend_iscsi.h \ esx/esx_device_monitor.c esx/esx_device_monitor.h \ esx/esx_secret_driver.c esx/esx_secret_driver.h \ esx/esx_nwfilter_driver.c esx/esx_nwfilter_driver.h \ diff --git a/src/esx/esx_storage_backend_iscsi.c b/src/esx/esx_storage_backend_iscsi.c new file mode 100644 index 0000000..fa4bf45 --- /dev/null +++ b/src/esx/esx_storage_backend_iscsi.c @@ -0,0 +1,807 @@ +/* + * esx_storage_backend_iscsi.c: ESX storage backend for iSCSI handling + * + * Copyright (C) 2012 Ata E Husain Bohra <ata.husain(a)hotmail.com> + * + * This library is free software; you can redistribute it and/or + * modify it under the terms of the GNU Lesser General Public + * License as published by the Free Software Foundation; either + * version 2.1 of the License, or (at your option) any later version. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

[libvirt] [PATCH] conf: fix virDomainNetGetActualDirect*() and BridgeName()
by Laine Stump 03 Dec '12

03 Dec '12

This resolves: https://bugzilla.redhat.com/show_bug.cgi?id=881480 These three functions: virDomainNetGetActualBridgeName virDomainNetGetActualDirectDev virDomainNetGetActualDirectMode return attributes that are in a union whose contents are interpreted differently depending on the actual->type and so they should only return non-0 when actual->type is 'bridge' (in the first case) or 'direct' (in the other two cases, but I had neglected to do that, so ...DirectDev() was returning bridge.brname (which happens to share the same spot in the union with direct.linkdev) if actual->type was 'bridge', and ...BridgeName was returning direct.linkdev when actual->type was 'direct'.

[libvirt] [PATCHv2 0/2] qemu: support live update of an interface's filter
by Laine Stump 03 Dec '12

03 Dec '12

These two patches enable making a live change to the nwfilter of a guest's interface via virDomainUpdateDeviceFlags (virsh update-device). Differences from V1: 1) add patch from Stefan Berger to do a proper comparison of the values stored in the filterparams hashtable. 2) simplify virNWFilterHashTableEqual to use Stefan's new function, and remove a couple of pointless comparisons based on Stefan's review.

[libvirt] [PATCH] virsh: Report errors if arguments of the schedinfo command are incorrect
by Peter Krempa 03 Dec '12

03 Dec '12

Libvirt's helper API's when called directly don't raise the error so that virsh remembers it. Subsequent calls to libvirt API's might reset the error. In case of schedinfo virDomainFree() in the cleanup section resets the error when virTypedParameterAssignFromStr() fails. This patch adds function vshSaveLibvirtError() that can be called after calling libvirt helper APIs to ensure the error is remembered. --- tools/virsh-domain.c | 8 ++++++-- tools/virsh.c | 9 +++++++++ tools/virsh.h | 1 + 3 files changed, 16 insertions(+), 2 deletions(-) diff --git a/tools/virsh-domain.c b/tools/virsh-domain.c index 73ebba9..1f7aff7 100644 --- a/tools/virsh-domain.c +++ b/tools/virsh-domain.c @@ -3512,8 +3512,10 @@ cmdSchedInfoUpdate(vshControl *ctl, const vshCmd *cmd, if (virTypedParameterAssign(&(params[nparams++]), param->field, param->type, - val) < 0) + val) < 0) { + vshSaveLibvirtError(); goto cleanup; + } continue; } @@ -3523,8 +3525,10 @@ cmdSchedInfoUpdate(vshControl *ctl, const vshCmd *cmd, if (virTypedParameterAssignFromStr(&(params[nparams++]), param->field, param->type, - set_val) < 0) + set_val) < 0) { + vshSaveLibvirtError(); goto cleanup; + } continue; } diff --git a/tools/virsh.c b/tools/virsh.c index dea3f82..322f778 100644 --- a/tools/virsh.c +++ b/tools/virsh.c @@ -240,6 +240,15 @@ virshErrorHandler(void *unused ATTRIBUTE_UNUSED, virErrorPtr error) virDefaultErrorFunc(error); } +/* Store a libvirt error that is from a helper API that doesn't raise errors + * so it doesn't get overwritten */ +void +vshSaveLibvirtError(void) +{ + virFreeError(last_error); + last_error = virSaveLastError(); +} + /* * Reset libvirt error on graceful fallback paths */ diff --git a/tools/virsh.h b/tools/virsh.h index ba44f42..6913ed1 100644 --- a/tools/virsh.h +++ b/tools/virsh.h @@ -346,6 +346,7 @@ struct _vshCtrlData { extern virErrorPtr last_error; void vshReportError(vshControl *ctl); void vshResetLibvirtError(void); +void vshSaveLibvirtError(void); /* allocation wrappers */ void *_vshMalloc(vshControl *ctl, size_t sz, const char *filename, int line); -- 1.8.0

[libvirt] [PATCHv2 0/3] IPv6 enhancements; put dnsmasq parameters in conf-file
by Gene Czarcinski 03 Dec '12

03 Dec '12

Rebased 30 Nov 2012 These three patch files are packaged together because they serially depend on each other. These files have been rebased to "v3" of the dnsmasq capabilities and bind-dynamic patches. The DHCPv6 support checks dnsmasq's version and requires a minimum of 2.64. Also, using dnsmasq for providing the RA service is checked against the dnsmasq version and is currently 2.64. As with IPv4, IPv6 DHCP is only one subnetwork on an interface. Additionally, if other IPv6 addresses are defined, a warning message is issued since the Router Advertisement service will support only state-full (DHCP) or state-less (SLAAC) addressing on a network interface (not both). Thus, the additional subnetworks will need to be manually configured to properly function. If dnsmasq provides the RA service, it also points to itself as a RDNSS (Recursive DNS Server) as part of the information is supplies. If IPv6 DHCP is not being run, then SLAAC addressing is supported for any IPv6 addresses specified.

[libvirt] [PATCH] Convert libxl driver to Xen 4.2

Based on a patch originally authored by Daniel De Graaf http://lists.xen.org/archives/html/xen-devel/2012-05/msg00565.html This patch converts the Xen libxl driver to support only Xen >= 4.2. Support for Xen 4.1 libxl is dropped since that version of libxl is designated 'technology preview' only and is incompatible with Xen 4.2 libxl.

[libvirt] fwd: RA support in dnsmasq
by Gene Czarcinski 30 Nov '12

30 Nov '12

I am sort-of cross posting this to the libvir-list because the bind-dynamic fix may have introduced an undesirable new "feature". I will be troubleshooting this. One thing I want to try is to build a dnsmasq with a fake version so that bind-interface is forced into use. Since this is occurring with a SLAAC address, I do not need DHCPv6 for this testing. Wait, since Laine put a lot of effort into parsing dnsmasq --help, I will just remove the bind-dynamic rather than changing the version.

However, I do not believe that this is the basic problem. When the problem occurs, one of the networks "suddenly" attempts to work with the real NIC rather than the virtual one defined in its config file. I slightly changed the IPv4 and IPv6 addresses defined for this network and the problem went away. I have also "just" seen the problem happen on another system which also had that virtual address defined. BTW, these configurations all use interface= and bind-dynamic rather than the "old" bind-interface with listen-address= specified for each specified IPv4 and IPv6 address. I had not noticed the problem previously. Why it occurs at all with just this specific address is puzzling. The configuration in which causes problems is: ------------------------------------------ # dnsmasq conf file created by libvirt strict-order domain-needed domain=net6 expand-hosts local=/net6/ pid-file=/var/run/libvirt/network/net6.pid bind-dynamic interface=virbr11 dhcp-range=192.168.6.128,192.168.6.254 dhcp-no-override dhcp-leasefile=/var/lib/libvirt/dnsmasq/net6.leases dhcp-lease-max=127 dhcp-hostsfile=/var/lib/libvirt/dnsmasq/net6.hostsfile addn-hosts=/var/lib/libvirt/dnsmasq/net6.addnhosts dhcp-range=fd00:beef:10:6::1,ra-only ------------------------------------------------- When I changed all the "6" to "160", the problem, disappeared. And there is another network defined almost the same with "8" instead of "6" and I have had no problems with it. The real NIC is configured as a DHCP client for both IPv4 and IPv6. It is assigned "nailed" addresses of 192.168.17.2/24 and fd00:dead:beef:17::2. And I just discovered why crazy stuff is happening (but I do not know what causes it) ... the P33p1 NIC has: inet6 fd00:beef:10:6:3285:a9ff:fe8f:e982/64 scope global dynamic And the reason why may be related to that NetworkManager goes through a verly long dance to bring up an interface. With dnsmasq autostarted for net6, it may have gotten there first ... but it should have not responded to p33p1 in any case. I am getting a little suspicious of dnsmasq with bind-dynamic!

[libvirt] [PATCH] qemu: Fix up the default machine type for QMP probing
by Viktor Mihajlovski 30 Nov '12

30 Nov '12

The default machine type must be stored in the first element of the caps->machineTypes array. This was done for help output parsing but not for QMP probing. Added a helper function qemuSetDefaultMachine to apply the same fix up for both probing methods. Further, it was necessary to set caps->nmachineTypes after QMP probing.

[libvirt] [PATCH v2] Introduce APIs for splitting/joining strings
by Daniel P. Berrange 30 Nov '12

30 Nov '12

From: "Daniel P. Berrange" <berrange(a)redhat.com> This introduces a few new APIs for dealing with strings. One to split a char * into a char **, another to join a char ** into a char *, and finally one to free a char ** There is a simple test suite to validate the edge cases too. No more need to use the horrible strtok_r() API, or hand-written code for splitting strings. Signed-off-by: Daniel P.

[libvirt] [PATCH] Introduce APIs for splitting/joining strings
by Daniel P. Berrange 30 Nov '12

30 Nov '12

From: "Daniel P. Berrange" <berrange(a)redhat.com> This introduces a few new APIs for dealing with strings. One to split a char * into a char **, another to join a char ** into a char *, and finally one to free a char ** There is a simple test suite to validate the edge cases too. No more need to use the horrible strtok_r() API, or hand-written code for splitting strings. Signed-off-by: Daniel P.

[libvirt] [PATCH] qemu: don't attempt undefined QMP commands
by Eric Blake 30 Nov '12

30 Nov '12

https://bugzilla.redhat.com/show_bug.cgi?id=872292 Libvirt should not attempt to call a QMP command that has not been documented in qemu.git - if future qemu introduces a command by the same name but with subtly different semantics, then libvirt will be broken when trying to use that command. See also this attempt to convert the three snapshot commands to QMP: https://lists.gnu.org/archive/html/qemu-devel/2012-07/msg01597.html although it looks like that will still not happen before qemu 1.3. That thread eventually decided that qemu would use the name 'save-vm' rather than 'savevm', which mitigates the fact that libvirt's attempt to use a QMP 'savevm' would be broken, but we might not be as lucky on the other commands. * src/qemu/qemu_monitor_json.c (qemuMonitorJSONSetCPU) (qemuMonitorJSONAddDrive, qemuMonitorJSONDriveDel) (qemuMonitorJSONCreateSnapshot, qemuMonitorJSONLoadSnapshot) (qemuMonitorJSONDeleteSnapshot): Use only HMP fallback for now. (qemuMonitorJSONAddHostNetwork, qemuMonitorJSONRemoveHostNetwork) (qemuMonitorJSONAttachDrive, qemuMonitorJSONGetGuestDriveAddress): Delete; QMP implies QEMU_CAPS_DEVICE, which prefers AddNetdev, RemoveNetdev, and AddDrive anyways. * src/qemu/qemu_monitor.c (qemuMonitorAddHostNetwork) (qemuMonitorRemoveHostNetwork, qemuMonitorAttachDrive): Reflect deleted commands. * src/qemu/qemu_monitor_json.h (qemuMonitorJSONAddHostNetwork) (qemuMonitorJSONRemoveHostNetwork, qemuMonitorJSONAttachDrive): Likewise. --- src/qemu/qemu_monitor.c | 9 +- src/qemu/qemu_monitor_json.c | 311 ++++-------------------------------------- src/qemu/qemu_monitor_json.h | 12 -- 3 files changed, 31 insertions(+), 301 deletions(-) diff --git a/src/qemu/qemu_monitor.c b/src/qemu/qemu_monitor.c index aef5044..43e45ef 100644 --- a/src/qemu/qemu_monitor.c +++ b/src/qemu/qemu_monitor.c @@ -2387,7 +2387,8 @@ int qemuMonitorAddHostNetwork(qemuMonitorPtr mon, } if (mon->json) - ret = qemuMonitorJSONAddHostNetwork(mon, netstr); + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", + _("JSON monitor should be using netdev_add")); else ret = qemuMonitorTextAddHostNetwork(mon, netstr); @@ -2418,7 +2419,8 @@ int qemuMonitorRemoveHostNetwork(qemuMonitorPtr mon, } if (mon->json) - ret = qemuMonitorJSONRemoveHostNetwork(mon, vlan, netname); + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", + _("JSON monitor should be using netdev_del")); else ret = qemuMonitorTextRemoveHostNetwork(mon, vlan, netname); return ret; @@ -2548,7 +2550,8 @@ int qemuMonitorAttachDrive(qemuMonitorPtr mon, } if (mon->json) - ret = qemuMonitorJSONAttachDrive(mon, drivestr, controllerAddr, driveAddr); + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", + _("JSON monitor should be using AddDrive")); else ret = qemuMonitorTextAttachDrive(mon, drivestr, controllerAddr, driveAddr); diff --git a/src/qemu/qemu_monitor_json.c b/src/qemu/qemu_monitor_json.c index 9fcd7e8..195d89f 100644 --- a/src/qemu/qemu_monitor_json.c +++ b/src/qemu/qemu_monitor_json.c @@ -2094,44 +2094,9 @@ cleanup: int qemuMonitorJSONSetCPU(qemuMonitorPtr mon, int cpu, int online) { - int ret; - virJSONValuePtr cmd = qemuMonitorJSONMakeCommand("cpu_set", - "U:cpu", (unsigned long long)cpu, - "s:state", online ?

[libvirt] [PATCH] storage: fix scsi detach regression with cgroup ACLs
by Eric Blake 30 Nov '12

30 Nov '12

https://bugzilla.redhat.com/show_bug.cgi?id=876828 Commit 38c4a9cc introduced a regression in hot unplugging of disks from qemu, where cgroup device ACLs were no longer being revoked (thankfully not a security hole: cgroup ACLs only prevent open() of the disk; so reverting the ACL prevents future abuse but doesn't stop abuse from an fd that was already opened before the ACL change). Commit 1b2ebf95 overlooked that there were two spots affected. * src/qemu/qemu_hotplug.c (qemuDomainDetachDiskDevice): Transfer backing chain before deletion. * src/qemu/qemu_driver.c (qemuDomainDetachDeviceDiskLive): Fix spacing (partly to ensure a different-looking patch). --- I blame git for letting me find this - I did a 'pull --rebase' on top of libvirt.git, and noticed that my working patch was still on the tree - it turns out that the hunk for qemu_hotplug.c is _identical_ except for the context of the function name needing a fix. I still wish git would be more vocal when it finds an alternate place to apply a patch when function names don't match. src/qemu/qemu_driver.c | 2 +- src/qemu/qemu_hotplug.c | 2 ++ 2 files changed, 3 insertions(+), 1 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index c37bdb9..ae98dbf 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -6070,7 +6070,7 @@ qemuDomainDetachDeviceDiskLive(virQEMUDriverPtr driver, if (disk->bus == VIR_DOMAIN_DISK_BUS_VIRTIO) ret = qemuDomainDetachPciDiskDevice(driver, vm, dev); else if (disk->bus == VIR_DOMAIN_DISK_BUS_SCSI) - ret = qemuDomainDetachDiskDevice(driver, vm, dev); + ret = qemuDomainDetachDiskDevice(driver, vm, dev); else if (dev->data.disk->bus == VIR_DOMAIN_DISK_BUS_USB) ret = qemuDomainDetachDiskDevice(driver, vm, dev); else diff --git a/src/qemu/qemu_hotplug.c b/src/qemu/qemu_hotplug.c index cfeae68..2d4a822 100644 --- a/src/qemu/qemu_hotplug.c +++ b/src/qemu/qemu_hotplug.c @@ -2091,6 +2091,8 @@ int qemuDomainDetachDiskDevice(virQEMUDriverPtr driver, virDomainDiskRemove(vm->def, i); + dev->data.disk->backingChain = detach->backingChain; + detach->backingChain = NULL; virDomainDiskDefFree(detach); if (virSecurityManagerRestoreImageLabel(driver->securityManager, -- 1.7.1

[libvirt] problems with current libvirt and qemu-kvm
by Gene Czarcinski 30 Nov '12

30 Nov '12

When I rebased my DHCPv6, etc. patches, I did that not only on to of Laine Stump's dnsmasq-capabiliotes/bind-dynamic updates but I also rebased to "current" git master. Well, the problem with the large number/frequent RTR-ADVERT syslog messages from dnsmasq that I had previously seen were fixed ... they stopped and dnsmasq produced expected results. But, starting virt-manager hung and there were new error messages in syslog about "internal error cannot find suitable emulator for X86_64. So I downgraded to a previous version that I knew worked and it did but my RTR-ADVERT messages are back. The "good" version uses a tarball created from git on November 19th and the "bad" version has a tarball created from git on November 29th. OK, before I start shuffling through the patches applied between those two date, does anyone have an idea what patches might be "guilty" ... for both issues ... fixing the RTR-ADVERT problem and giving libvirtd/qemu-kvm indigestion? I am not griping. When you run on the "leading edge", you expect a few arrows in your back. Any suggesting on testing will also be appreciated. Gene

[libvirt] Next release planning
by Daniel Veillard 30 Nov '12

30 Nov '12

Reminder, we are shooting for 1.0.1 release by mid December. I will be away next week and probably out of reach, and it looks unlikely i will have the bandwidth to start the freeze before Monday 10 possibly Tuesday 11. So there is a bit more than a week to push API and features for 1.0.1. Then 1.0.2 will occur at the end of January.

[libvirt] [PATCHv3 0/3] network: resolve CVE 2012-3411
by Laine Stump 29 Nov '12

29 Nov '12

(This obsoletes the V2 patches I sent yesterday: https://www.redhat.com/archives/libvir-list/2012-November/msg01216.html ) This patch series resolves the libvirt part of CVE 2012-3411: https://bugzilla.redhat.com/show_bug.cgi?id=833033 Further details are in PATCH 3/3. The changes from V1 to V3: (resulting from Doug Goldstein's review, and a comment in the BZ record from the CVE reporter, David Woodhouse) 1) rework dnsmasqCapsRefresh() to create a new caps object if it's given a NULL object (function now gets dnsmasqCapsPtr* instead of dnsmasCapsPtr). This makes it possible to recover properly if dnsmasq is installed after libvirtd has already been started. 2) Add the following before each run of dnsmasq: virCommandAddEnvPassCommon(cmd); virCommandClearCaps(cmd); 3) Fixed a missing space after comma :-) 4) remove empty if () { } around initial call to dnsmasqCapsNewFromBinary() in bridge_driver.c 5) include FEC0::/10 as a "local" range when checking for private addresses to allow in the absence of an updated dnsmasq.

[libvirt] [PATCH 0/3] IPv6 enhancements; put dnsmasq parameters in conf-file
by Gene Czarcinski 29 Nov '12

29 Nov '12

These three patch files are packaged together because they serially depend on each other. These files have been rebased to "v3" of the dnsmasq capabilities and bind-dynamic patches. The DHCPv6 support checks dnsmasq's version and requires a minimum of 2.64. Also, using dnsmasq for providing the RA service is checked against the dnsmasq version and is currently 2.64. As with IPv4, IPv6 DHCP is only one subnetwork on an interface. Additionally, if other IPv6 addresses are defined, a warning message is issued since the Router Advertisement service will support only state-full (DHCP) or state-less (SLAAC) addressing on a network interface (not both). Thus, the additional subnetworks will need to be manually configured to properly function. If dnsmasq provides the RA service, it also points to itself as a RDNSS (Recursive DNS Server) as part of the information is supplies. If IPv6 DHCP is not being run, then SLAAC addressing is supported for any IPv6 addresses specified.

[libvirt] Globally Reserve Resources for Host
by Dusty Mabe 29 Nov '12

29 Nov '12

Hi, I am interested in the capability to globally reserve resources(cpu and memory) for a KVM host. I know you can configure memory limits for each guest (http://libvirt.org/formatdomain.html#elementsMemoryTuning) but would like the ability to reserve host cpu and memory without having to actively do it by modifying each guests xml. For clarity, what I mean by "reserve resources" is that there are certain cpus and a certain amount of memory that guests will never have access to. This can be achieved using cgroups. Does anyone think this functionality would be useful? This is primarily to prevent the host from being starved when the allocation of guests have the host overcommitted/oversubscribed. Note: I think vmware has a similar functionality, but I am not sure as I don't really use vmware http://blogs.technet.com/b/virtualpfe/archive/2011/08/29/hyper-v-dynamic-me… Thanks for any thoughts, Dusty

[libvirt] [PATCH] network: fix crash when portgroup has no name
by Laine Stump 29 Nov '12

29 Nov '12

This resolves: https://bugzilla.redhat.com/show_bug.cgi?id=879473 The name attribute is required for portgroup elements (yes, the RNG specifies that), and there is code in libvirt that assumes it is non-null. Unfortunately, the portgroup parsing function wasn't checking for lack of portgroup. One adverse result of this was that attempts to update a network by adding a portgroup with no name would cause libvirtd to segfault. For example: virsh net-update default add portgroup "<portgroup default='yes'/>" This patch causes virNetworkPortGroupParseXML to fail if no name is specified, thus avoiding any later problems. --- src/conf/network_conf.c | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/src/conf/network_conf.c b/src/conf/network_conf.c index 228951d..6ce2e63 100644 --- a/src/conf/network_conf.c +++ b/src/conf/network_conf.c @@ -1175,6 +1175,12 @@ virNetworkPortGroupParseXML(virPortGroupDefPtr def, /* grab raw data from XML */ def->name = virXPathString("string(./@name)", ctxt); + if (!def->name) { + virReportError(VIR_ERR_XML_ERROR, "%s", + _("Missing required name attribute in portgroup")); + goto error; + } + isDefault = virXPathString("string(./@default)", ctxt); def->isDefault = isDefault && STRCASEEQ(isDefault, "yes"); -- 1.7.11.7

[libvirt] [PATCH 0/3] qemu: QMP Capability Probing Fixes
by Viktor Mihajlovski 29 Nov '12

29 Nov '12

QMP Capability probing will fail if the QEMU process cannot create the monitor socket file in /var/lib/libvirt/qemu. This is the case if the configured QEMU user is not root, but QEMU is run under root to perfom the probing. The suggested solution is to run QEMU as qemu user for probing as well. As it happens, this developed into a mini-series: it was necessary to let libvirt handle the pid file as this is stored in root-owned directory /var/run/libvirt/qemu. This prompted a race condition opening a socket. Last but not least caps->version was not filled with QMP probing.

[libvirt] [PATCH 1/2 v2] node_memory: Do not fail if there is parameter unsupported
by Osier Yang 29 Nov '12

29 Nov '12

It makes no sense to fail the whole getting command if there is parameter unsupported by the kernel. This patch fixes it by omitting the unsupported parameter for getMemoryParameters. And For setMemoryParameters, this checks if there is unsupported parameter up front of the setting, and just returns failure if not all parameters are supported. --- v1 - v2: * Change the behaviour of APIs with regard to the agreement in https://www.redhat.com/archives/libvir-list/2012-November/msg01164.html --- src/libvirt.c | 11 +++-- src/nodeinfo.c | 127 ++++++++++++++++++++++++++++++++++++------------------- 2 files changed, 89 insertions(+), 49 deletions(-) diff --git a/src/libvirt.c b/src/libvirt.c index 4af6089..e851049 100644 --- a/src/libvirt.c +++ b/src/libvirt.c @@ -6746,10 +6746,10 @@ error: * @nparams: pointer to number of memory parameters; input and output * @flags: extra flags; not used yet, so callers should always pass 0 * - * Get all node memory parameters.

[libvirt] [PATCH] qemu: support live update of an interface's filter
by Laine Stump 29 Nov '12

29 Nov '12

Since we can't (currently) rely on the ability to provide blanket support for all possible network changes by calling the toplevel netdev hostside disconnect/connect functions (due to qemu only supporting a lockstep between initialization of host side and guest side of devices), in order to support live change of an interface's nwfilter we need to make a special purpose function to only call the nwfilter teardown and setup functions if the filter for an interface (or its parameters) changes. The pattern is nearly identical to that used to change the bridge that an interface is connected to. This patch was inspired by a request from Guido Winkelmann <guido(a)sagersystems.de>, who tested an earlier version, and wrote an initial version of the nwfilterHashTable comparison function. I didn't spend any time trying to understand the contents of the nwfilterHashTable entries, or whether the comparison function is fully/correctly comparing the entries. I would appreciate if someone with better knowledge of that data structure (Stefan?) could check it out and provide suggestions. --- src/conf/nwfilter_params.c | 24 ++++++++++++++++++++ src/conf/nwfilter_params.h | 4 +++- src/libvirt_private.syms | 1 + src/qemu/qemu_hotplug.c | 55 +++++++++++++++++++++++++++++++++++++++++++--- 4 files changed, 80 insertions(+), 4 deletions(-) diff --git a/src/conf/nwfilter_params.c b/src/conf/nwfilter_params.c index 6dc4baa..e42a54c 100644 --- a/src/conf/nwfilter_params.c +++ b/src/conf/nwfilter_params.c @@ -764,6 +764,30 @@ err_exit: return -1;

[libvirt] [PATCH 0/4] Support for sending signals to guest processes
by Daniel P. Berrange 29 Nov '12

29 Nov '12

One of the things people want to be able todo with LXC is to send arbitrary signals to processes inside the container. This series introduces a virDomainSendProcessSignal API for that purpose. The LXC driver impl is limited to sending signals to the "init" pid (ie pid == 1), but in the future we'll extend this to arbitrary container PIDs (via /proc/$PID/ns/pid + setns()). If the QEMU guest agent had a suitable command we could support this for QEMU too.

[libvirt] [PATCH] maint: Fix use of invalid reboot flags
by Michal Privoznik 28 Nov '12

28 Nov '12

Throughout the code, we've always used VIR_DOMAIN_SHUTDOWN* flags even for virDomainReboot() API and its implementation. Fortunately, the appropriate macros has the same value. But if we want to keep things consistent, we should be using the correct macros. This patch doesn't break anything, luckily. --- Worth backporting to v0.10.2-maint and v0.9.11-maint (will cause conflict)?

[libvirt] Any plans to extend openvswitch configuration in libvirt?
by james robson 28 Nov '12

28 Nov '12

Hello All, Are there any current plans to extend the openvswitch port configuration options to include the 'native-tagged' and 'native-untagged' vlan modes? I'm currently setting up a test lab that is going to require the 'native-untagged' vlan mode on openvswitch and would prefer to keep these setting with the other network configuration for my virtual machines. I can produce a patch for this functionality myself, but don't want to duplicate effort if someone else is all ready working on it. Protected by Websense Hosted Email Security -- www.websense.com

[libvirt] [PATCHv2 0/3] util: capabilities detection for dnsmasq
by Laine Stump 28 Nov '12

28 Nov '12

This patch series resolves the libvirt part of CVE 2012-3411: https://bugzilla.redhat.com/show_bug.cgi?id=833033 Further details are in PATCH 3/3. The changes from V1 are all in PATCH 1/3 (resulting from Doug Goldstein's review): 1) rework dnsmasqCapsRefresh() to create a new caps object if it's given a NULL object (function now gets dnsmasqCapsPtr* instead of dnsmasCapsPtr). This makes it possible to recover properly if dnsmasq is installed after libvirtd has already been started. 2) Add the following before each run of dnsmasq: virCommandAddEnvPassCommon(cmd); virCommandClearCaps(cmd); 3) Fixed a missing space after comma :-)

[libvirt] [PATCH v1 00/11] Rework storage migration
by Michal Privoznik 28 Nov '12

28 Nov '12

This patch set re-implements migration with storage for enough new qemu. Currently, you can migrate a domain to a host without need for shared storage. This is done by setting 'blk' or 'inc' attribute (representing VIR_MIGRATE_NON_SHARED_DISK and VIR_MIGRATE_NON_SHARED_INC flags respectively) of 'migrate' monitor command. However, the qemu implementation is buggy and applications are advised to switch to new impementation which, moreover, offers some nice features, like migrating only explicitly specified disks. The new functionality is controlled via 'nbd-server-*' and 'drive-mirror' commands. The flow is meant to look like this: 1) User invokes libvirt's migrate functionality. 2) libvirt checks that no block jobs are active on the source. 3) libvirt starts the destination QEMU and sets up the NBD server using the nbd-server-start and nbd-server-add commands. 4) libvirt starts drive-mirror with a destination pointing to the remote NBD server, for example nbd:host:port:exportname=diskname (where diskname is the -drive id specified on the destination). 5) once all mirroring jobs reach steady state, libvirt invokes the migrate command. 6) once migration completed, libvirt invokes the nbd-server-stop command on the destination QEMU. If we just skip the 2nd step and there is an active block-job, qemu will fail in step 4. No big deal. Since we try to NOT break migration and keep things compatible, this feature is enabled iff both sides support it. Since there's obvious need for some data transfer between src and dst, I've put it into qemuCookieMigration: 1) src -> dest: (QEMU_MIGRATION_PHASE_BEGIN3 -> QEMU_MIGRATION_PHASE_PREPARE) <nbd> <disk src='/var/lib/libvirt/images/f17.img' size='17179869184'/> </nbd> Hey destination, I know how to use this cool new feature. Moreover, these are the paths I'll send you. Each file is X bytes big. It's one of the prerequisite - the file on dst exists and has at least the same size as on dst. 2) dst -> src: (QEMU_MIGRATION_PHASE_PREPARE -> QEMU_MIGRATION_PHASE_PERFORM3) <nbd port='X'/> Okay, I (destination) support this feature as well. I've created all files as you (src) told me to and you can start rolling data. I am listening on port X. 3) src -> dst: (QEMU_MIGRATION_PHASE_PERFORM3 -> QEMU_MIGRATION_PHASE_FINISH3) <nbd port='-1'/> Migration completed, destination, you may shut the NBD server down. If either src or dst doesn't support NBD, it is not used and whole process fall backs to old implementation.

[libvirt] RFC: adding configuration for standard dhcp options to <network>
by Laine Stump 28 Nov '12

28 Nov '12

There have been multiple requests over the last couple years to make the DHCP server of libvirt's virutal networks more configurable (for example, see the following BZ: https://bugzilla.redhat.com/show_bug.cgi?id=824573 ). You can see a full list of the options supported by dnsmasq with this command: dnsmasq --help dhcp The biggest question here is in exactly how to represent the options in the network XML. I can see a few different options, among them: 1) make each option its own element within <dhcp>, e.g.: <dnsServer family='ipv4' address='x.x.x.x'/> <dnsServer family='ipv6' address='xxxx:xxxx::1'/> <ntpServer address='y.y.y.y'/> <smtpServer address='z.z.z.z'/> 2) A variation of (1) where each option could appear only once, but with two attributes, one for ipv6 address and one for ipv4: <dnsServer address4='x.x.x.x'address6='xxxx:xxxx::1'/> <ntpServer address4='y.y.y.y'/> 3) have a repeatable "option" element (again, a subelement of <dhcp> that can contain any number of the options as attributes: <option family='ipv4' dnsServer='x.x.x.x' ntpServer='y.y.y.y' smtpServer='z.z.z.z'/> <option family='ipv6' dnsServer='xxxx:xxxx:1'/> (in this case, we may or may not support repeating <option> to add more options for the same family). 4) yet another variation, where each option is a subelement of <option family='xxxx'>: <option family='ipv4'> <dnsServer>x.x.x.x</dnsServer> <ntpServer>y.y.y.y</ntpServer> <smtpServer>z.z.z.z</smtpServer> </option> <option family='ipv6'> <dnsServer>xxxx:xxxx::1</dnsServer> </option> I'm not sure which of these would be more straightforward for a user. One thought I've had is that dnsmasq at least allows specifying different groups of guest addresses (with a "tag") and applying different options to addresses with different tags. I don't know if we'll ever use that capability, but if we do it *seems* like any of these methods could be adapted to specifying multiple groups. Does anyone have a preference? (I have a narrow preference for (1), simply because it was the first to come to my mind, but could easily be swayed to one of the others, or something else, given a logical reason).

When keyboard interactive authentication is disabled on the remote host the usual way is to request a password and authenticate using tunneled password authentication.

[libvirt] [v0.10.2-maint][PATCH] qemu: Always format CPU topology
by Michal Privoznik 27 Nov '12

27 Nov '12

From: Jiri Denemark <jdenemar(a)redhat.com> When libvirt cannot find a suitable CPU model for host CPU (easily reproducible by running libvirt in a guest), it would not provide CPU topology in capabilities XML either. Even though CPU topology is known and can be queried by virNodeGetInfo. With this patch, CPU topology will always be provided in capabilities XML regardless on the presence of CPU model.

[libvirt] [PATCH] storage: fix device detach regression with cgroup ACLs
by Eric Blake 27 Nov '12

27 Nov '12

https://bugzilla.redhat.com/show_bug.cgi?id=876828 Commit 38c4a9cc introduced a regression in hot unplugging of disks from qemu, where cgroup device ACLs were no longer being revoked (thankfully not a security hole: cgroup ACLs only prevent open() of the disk; so reverting the ACL prevents future abuse but doesn't stop abuse from an fd that was already opened before the ACL change). The actual regression is due to a latent bug. The hot unplug code was computing the set of files to do cgroup ACL revocation based on the XML passed in by the user, rather than based on the domain's details on which disk was being deleted. As long as the revoke path was always recomputing the backing chain, this didn't really matter; but now that we want to compute the chain exactly once and remember that computation, we need to hang on to the backing chain until after the revoke has happened. * src/qemu/qemu_hotplug.c (qemuDomainDetachPciDiskDevice): Transfer backing chain before deletion. --- The patch is deceptively small for how long it took me to figure out why we had a regression :) src/qemu/qemu_hotplug.c | 2 ++ 1 files changed, 2 insertions(+), 0 deletions(-) diff --git a/src/qemu/qemu_hotplug.c b/src/qemu/qemu_hotplug.c index ae8381e..0bc2259 100644 --- a/src/qemu/qemu_hotplug.c +++ b/src/qemu/qemu_hotplug.c @@ -1999,6 +1999,8 @@ int qemuDomainDetachPciDiskDevice(struct qemud_driver *driver, virDomainDiskRemove(vm->def, i); + dev->data.disk->backingChain = detach->backingChain; + detach->backingChain = NULL; virDomainDiskDefFree(detach); if (virSecurityManagerRestoreImageLabel(driver->securityManager, -- 1.7.1

[libvirt] [PATCH] S390: Assign default model "virtio" for network interfaces
by Viktor Mihajlovski 27 Nov '12

27 Nov '12

If a network interface model is not specified, libvirt will run into an unchecked NULL pointer coredump. On the other hand if the empty model is ignored, a PCI bus address would be generated, which is not supported by S390. Since the only valid network type model for S390 is virtio, we use this as the default value, which is the same for QEMU.

[libvirt] [PATCH 0/6] Unprivileged SG_IO support
by Osier Yang 27 Nov '12

27 Nov '12

Hi, As a result of RFC [1], this implements the unprivleged SG_IO support. Though this is a bit rushed, and I still have no chance to test it yet, but I'd like see an earlier reviewing. @Paolo, please let me known once you have a kernel build with the new sysfs knob support. Thanks! Osier Yang (6): unpriv_sgio: Add docs and rng schema for new XML unpriv_sgio unpriv_sgio: Parse and format the new XML unpriv_sgio: Prepare helpers for unpriv_sgio setting unpriv_sgio: Manage unpriv_sgio in domain's lifecyle unpriv_sgio: Do not restore unpriv_sgio if the disk is being used unpriv_sgio: Error out if the unpriv_sgio setting conflicts with others docs/formatdomain.html.in | 10 +- docs/schemas/domaincommon.rng | 52 ++++-- src/conf/domain_conf.c | 168 ++++++++++++++++++-- src/conf/domain_conf.h | 18 ++ src/libvirt_private.syms | 6 + src/qemu/qemu_process.c | 54 +++++++ src/util/util.c | 154 ++++++++++++++++++ src/util/util.h | 7 + ...l2argv-disk-scsi-lun-passthrough-upriv-sgio.xml | 32 ++++ tests/qemuxml2xmltest.c | 1 + 10 files changed, 472 insertions(+), 30 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-scsi-lun-passthrough-upriv-sgio.xml [1] https://www.redhat.com/archives/libvir-list/2012-November/msg00988.html Regards, Osier

[libvirt] libvirt [PATCHv2 1/2] Refactor ESX storage driver to implement facade pattern
by Ata E Husain Bohra 26 Nov '12

26 Nov '12

The patch refactors the current ESX storage driver due to following reasons: 1. Given most of the public APIs exposed by the storage driver in Libvirt remains same, ESX storage driver should not implement logic specific for only one supported format (current implementation only supports VMFS). 2. Decoupling interface from specific storage implementation gives us an extensible design to hook implementation for other supported storage formats. This patch refactors the current driver to implement it as a facade pattern i.e. the driver exposes all the public libvirt APIs, but uses backend drivers to get the required task done. The backend drivers provide implementation specific to the type of storage device. File changes: ------------------ esx_storage_driver.c ----> esx_storage_driver.c (base storage driver) | |---> esx_storage_backend_vmfs.c (VMFS backend) One of the task base storage driver need to do is to decide which backend driver needs to be invoked for a given request. This approach extends virStoragePool and virStorageVol to store extra parameters: 1. privateData: stores pointer to respective backend storage driver. 2. privateDataFreeFunc: stores cleanup function pointer. virGetStoragePool and virGetStorageVol are modfiied to accept these extra parameters as user params. virStoragePoolDispose and virStorageVolDispose checks for cleanup operation if available. --- daemon/remote.c | 6 +- src/Makefile.am | 1 + src/conf/storage_conf.c | 3 +- src/datatypes.c | 25 +- src/datatypes.h | 24 +- src/esx/esx_driver.c | 6 +- src/esx/esx_storage_backend_vmfs.c | 1491 ++++++++++++++++++++++++++++++++++++ src/esx/esx_storage_backend_vmfs.h | 30 + src/esx/esx_storage_driver.c | 1319 +++++-------------------------- src/esx/esx_vi.c | 5 +- src/esx/esx_vi.h | 3 +- src/parallels/parallels_storage.c | 24 +- src/remote/remote_driver.c | 6 +- src/storage/storage_driver.c | 28 +- src/test/test_driver.c | 30 +- src/vbox/vbox_tmpl.c | 14 +- 16 files changed, 1843 insertions(+), 1172 deletions(-) create mode 100644 src/esx/esx_storage_backend_vmfs.c create mode 100644 src/esx/esx_storage_backend_vmfs.h diff --git a/daemon/remote.c b/daemon/remote.c index 340d07d..41b8ea8 100644 --- a/daemon/remote.c +++ b/daemon/remote.c @@ -4651,14 +4651,16 @@ get_nonnull_interface(virConnectPtr conn, remote_nonnull_interface iface) static virStoragePoolPtr get_nonnull_storage_pool(virConnectPtr conn, remote_nonnull_storage_pool pool) { - return virGetStoragePool(conn, pool.name, BAD_CAST pool.uuid);

[libvirt] Proposal: no dnsmasq (no dhcp and no dns) and no radvd option
by Gene Czarcinski 26 Nov '12

26 Nov '12

Laine mentioned something yesterday that got me to thinking: being able to specify that dnsmasq is not to be started for an interface. Let me expand that by saying that libvirt would not start dnsmasq for either dns or dhcp and also would not start radvd. However, the IPv4 and IPv6 gateway addresses would be defined on the virtual network interface and the "usual" iptables and ip6tables rules would be in force. This would allow a user to configure dnsmasq to meet any user desires or use something completely different instead of dnsmasq. Questions: Useful? Worth the time and effort? And then there is how should this be specified in the network xml file? ... some new parameter? ... A subperameter of <dns> such as <dns disable='yes' /> ? ... a subparameter of <bridge> such as <bridge name="virbr0" dns="disable" /> ? Comments? Suggestions? Gene

[libvirt] Is DBus a hard dependency
by Guido Günther 26 Nov '12

26 Nov '12

Hi, currently running libvirtd without DBus fails due to: error : nwfilterDriverStartup:208 : DBus matches could not be installed. Disabling nwfilter driver error : virDBusGetSystemBus:77 : internal error Unable to get DBus system bus connection: Failed to connect to socket /var/run/dbus/system_bus_socket: No such file or directory error : virStateInitialize:810 : Initialization of NWFilter state driver failed error : daemonRunStateInit:784 : Driver state initialization failed because we fail driver initialization hard in nwfilter_driver.c: if (nwfilterDriverInstallDBusMatches(sysbus) < 0) { VIR_ERROR(_("DBus matches could not be installed. Disabling nwfilter " "driver")); /* * unfortunately this is fatal since virNWFilterTechDriversInit * may have caused the ebiptables driver to use the firewall tool * but now that the watches don't work, we just disable the nwfilter * driver */ goto error; } I wonder if this on prupose or if we can just make this a soft error and go on without DBus? At least in the !HAVE_FIREWALLD case it should be o.k. to continue. Shouldn't it? See attached patch. Cheers, -- Guido

[libvirt] [PATCH] Add detailed error information to journal
by Miloslav Trmač 26 Nov '12

26 Nov '12

When logging an error, don't throw away the detailed information. Example record when using the journald output: MESSAGE=Domain not found PRIORITY=4 LIBVIRT_SOURCE=error CODE_FILE=../../src/test/test_driver.c CODE_LINE=1406 CODE_FUNC=testLookupDomainByName DOMAIN=12 CODE=42 The format used in other output destinations (e.g. "syslog", "file") is still unchanged. The "domain" and "code" numbers are part of the libvirt ABI in <libvirt/virterror.h>; therefore log processing tools can rely on them, unlike the text log string (which is translated depending on locale, and may be modified for other reasons as well). Alternatively, the "domain" and "code" fields could contain strings instead of numbers, but it's not clear that it's worth it: Advantages of numbers: * the numbers are shorter * the ABI guarantees that the numbers won't change Disadvantages of strings: * adding a ABI-stable string mapping for virErrorNumber would result in additional work each time a new error number is added (note that virErrorMsg cannot be used for this because it is translated) * a change in the string mapping would be less likely to be noticed The advantage of using strings is more readability, but note that the "msg" field above already contains a readable description of the error. The inability to allocate memory imposes a fixed limit on the number of metadata fields that can be supported by the journal; fields beyond this limit are silently dropped (but the initial part of the message sent). This was implemented in the previous patch, here we just increase the limit to 32 fields total. Signed-off-by: Miloslav Trmač <mitr(a)redhat.com> --- This version drops logging the str[123] and int[12] fields. The META_ADD_STRING macro is unused; it was left there just to demonstrate the use of the API in case someone wanted to add more error-specific information. --- src/util/logging.c | 13 +++++++++++-- src/util/virterror.c | 23 ++++++++++++++++++++++- 2 files changed, 33 insertions(+), 3 deletions(-) diff --git a/src/util/logging.c b/src/util/logging.c index e8fed55..dbffaa1 100644 --- a/src/util/logging.c +++ b/src/util/logging.c @@ -1125,7 +1125,7 @@ virLogOutputToJournald(virLogSource source, int linenr, const char *funcname, const char *timestamp ATTRIBUTE_UNUSED, - virLogMetadataPtr metadata ATTRIBUTE_UNUSED, + virLogMetadataPtr metadata, unsigned int flags, const char *rawstr, const char *str ATTRIBUTE_UNUSED, @@ -1145,7 +1145,7 @@ virLogOutputToJournald(virLogSource source, * and where unprivileged users can create files. */ char path[] = "/dev/shm/journal.XXXXXX"; -# define NUM_FIELDS 6 +# define NUM_FIELDS 32 struct iovec iov[NUM_FIELDS * 5]; char iov_bufs[NUM_FIELDS][JOURNAL_BUF_SIZE]; struct journalState state; @@ -1162,6 +1162,15 @@ virLogOutputToJournald(virLogSource source, journalAddString(&state, "CODE_FILE", filename); journalAddInt(&state, "CODE_LINE", linenr); journalAddString(&state, "CODE_FUNC", funcname); + if (metadata != NULL) { + while (metadata->key != NULL) { + if (metadata->s != NULL) + journalAddString(&state, metadata->key, metadata->s); + else + journalAddInt(&state, metadata->key, metadata->i); + metadata++; + } + } memset(&sa, 0, sizeof(sa)); sa.sun_family = AF_UNIX; diff --git a/src/util/virterror.c b/src/util/virterror.c index 213188e..10b627f 100644 --- a/src/util/virterror.c +++ b/src/util/virterror.c @@ -619,6 +619,8 @@ virRaiseErrorFull(const char *filename ATTRIBUTE_UNUSED, virErrorPtr to; char *str; int priority; + virLogMetadata meta[3]; + size_t i; /* * All errors are recorded in thread local storage @@ -676,10 +678,29 @@ virRaiseErrorFull(const char *filename ATTRIBUTE_UNUSED, priority = virErrorLevelPriority(level); if (virErrorLogPriorityFilter) priority = virErrorLogPriorityFilter(to, priority); + + i = 0; +#define META_ADD_STRING(KEY, VALUE) \ + do { \ + meta[i].key = (KEY); \ + meta[i].s = (VALUE); \ + i++; \ + } while (0) +#define META_ADD_INT(KEY, VALUE) \ + do { \ + meta[i].key = (KEY); \ + meta[i].s = NULL; \ + meta[i].i = (VALUE); \ + i++; \ + } while (0) + + META_ADD_INT("DOMAIN", domain); + META_ADD_INT("CODE", code); + meta[i].key = NULL; virLogMessage(virErrorLogPriorityFilter ?

[libvirt] [PATCHv2 0/2] S390: Adding support for SCLP Console
by Viktor Mihajlovski 26 Nov '12

26 Nov '12

The S390 architecture comes with a native console type (SCLP console) which is now also supported by current QEMU. This series is enabling libvirt to configure S390 domains with SCLP consoles. The domain XML has to be extended for the new console target types 'sclp' and 'sclplm' (line mode = dumb). As usual the QEMU driver must do capability probing in order to find out whether SCLP is supported and format the QEMU command line for the new console type.

[libvirt] [PATCH] lxc: Avoid segfault of libvirt_lxc helper on early cleanup paths
by Peter Krempa 26 Nov '12

26 Nov '12

Early jumps to the cleanup label caused a crash of the libvirt_lxc container helper as the cleanup section called virLXCControllerDeleteInterfaces(ctrl) without checking the ctrl argument for NULL. The argument was de-referenced soon after. $ /usr/libexec/libvirt_lxc /usr/libexec/libvirt_lxc: missing --name argument for configuration Segmentation fault --- src/lxc/lxc_controller.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/src/lxc/lxc_controller.c b/src/lxc/lxc_controller.c index a9d2d40..ea5bc58 100644 --- a/src/lxc/lxc_controller.c +++ b/src/lxc/lxc_controller.c @@ -1672,7 +1672,8 @@ int main(int argc, char *argv[]) cleanup: virPidFileDelete(LXC_STATE_DIR, name); - virLXCControllerDeleteInterfaces(ctrl); + if (ctrl) + virLXCControllerDeleteInterfaces(ctrl); for (i = 0 ; i < nttyFDs ; i++) VIR_FORCE_CLOSE(ttyFDs[i]); VIR_FREE(ttyFDs); -- 1.8.0

[libvirt] [PATCH] lxc: Don't crash if no security driver is specified in libvirt_lxc
by Peter Krempa 26 Nov '12

26 Nov '12

When no security driver is specified libvirt_lxc segfaults as a debug message tries to access security labels for the container that are not present.
