This resolves: https://bugzilla.redhat.com/show_bug.cgi?id=868483 virNetworkUpdate, virNetworkDefine, and virNetworkCreate all three allow network definitions to contain multiple <portgroup> elements with default='yes'.

[libvirt] 0.10.2 virtualport profileid (802.1Qbh) malformed
by Tom Lanyon 21 Oct '12

21 Oct '12

Hi, I've just upgraded a test libvirtd host to 0.10.2 from 0.9.4 to be able to make use of the new 'virsh net-update add portgroup' live updates, however can't get my private/802.1Qbh interfaces working at all after the upgrade. Trying to start an existing domain or install a new domain after the upgrade gives: "ERROR internal error corrupted profileid string" and a corresponding error in the libvirtd log: "error : virNetDevVPortProfileMerge:381 : internal error corrupted profileid string" I've tried all sorts of profileid combinations and tried defining the virtualport in the domain instead of in the network, to no avail. The source indicates this is to do with a malformed (not null terminated) profile id when merging the port profile. Why would this be happening? Any hints how to debug it? My example network definition: <network> <name>testnet</name> <uuid>76d32a2d-8433-6873-9c15-cdae30e7a632</uuid> <forward dev='eth1' mode='private'> <interface dev='eth1'/> <interface dev='eth2'/> <interface dev='eth3'/> ... </forward> <portgroup name='server1' default='yes'> <virtualport type='802.1Qbh'> <parameters profileid='profile-server1'/> </virtualport> </portgroup> <portgroup name='server2'> <virtualport type='802.1Qbh'> <parameters profileid='profile-server2'/> </virtualport> </portgroup> <portgroup name='server3'> <virtualport type='802.1Qbh'> <parameters profileid='profile-server3'/> </virtualport> </portgroup> </network> and a domain definition which throws an error on start-up: <interface type='network'> <mac address='52:54:00:d1:94:5f'/> <source network='testnet' portgroup='server1'/> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> Tom

[libvirt] [PATCH] network: free/null newDef if network fails to start
by Laine Stump 20 Oct '12

20 Oct '12

https://bugzilla.redhat.com/show_bug.cgi?id=866364 pointed out a crash due to virNetworkObjAssignDef free'ing network->newDef without NULLing it afterward. A fix for this is in upstream commit b7e9202401ebaa039b8f05acdefda8c24081537a. While the NULLing of newDef was a legitimate fix, newDef should have already been empty (NULL) anyway (as indicated in the comment that was deleted by that commit). The reason that newDef had a non-NULL value (i.e. the root cause) was that networkStartNetwork() had failed after populating network->newDef, but then neglected to free/NULL newDef in the cleanup. (A bit of background here: network->newDef should contain the persistent config of a network when a network is active (and of course only when it is persisten), and NULL at all other times. There is also a network->def which should contain the persistent definition of the network when it is inactive, and the current live state at all other times. The idea is that you can make changes to network->newDef which will take effect the next time the network is restarted, but won't mess with the current state of the network (virDomainObj has a similar pair of virDomainDefs that behave in the same fashion). Personally I think there should be a network->live and network->config, and the location of the persistent config should *always* be in network->config, but that's for a later cleanup). Since I love things to be symmetric, I created a new function called virNetworkObjUnsetDefTransient(), which reverses the effects of virNetworkObjSetDefTransient(). I don't really like the name of the new function, but then I also didn't really like the name of the old one either (it's just named that way to match a similar function in the domain conf code). --- src/conf/network_conf.c | 14 ++++++++++++++ src/conf/network_conf.h | 1 + src/libvirt_private.syms | 1 + src/network/bridge_driver.c | 12 ++++-------- 4 files changed, 20 insertions(+), 8 deletions(-) diff --git a/src/conf/network_conf.c b/src/conf/network_conf.c index 0f7470d..2f9ad2e 100644 --- a/src/conf/network_conf.c +++ b/src/conf/network_conf.c @@ -352,6 +352,20 @@ virNetworkObjSetDefTransient(virNetworkObjPtr network, bool live) return network->newDef ? 0 : -1; } +/* virNetworkObjUnsetDefTransient: + * + * This *undoes* what virNetworkObjSetDefTransient did. + */ +void +virNetworkObjUnsetDefTransient(virNetworkObjPtr network) +{ + if (network->def) { + virNetworkDefFree(network->def); + network->def = network->newDef; + network->newDef = NULL; + } +} + /* * virNetworkObjGetPersistentDef: * @network: network object pointer diff --git a/src/conf/network_conf.h b/src/conf/network_conf.h index 55502fb..4c0c8c1 100644 --- a/src/conf/network_conf.h +++ b/src/conf/network_conf.h @@ -253,6 +253,7 @@ int virNetworkObjAssignDef(virNetworkObjPtr network, const virNetworkDefPtr def, bool live); int virNetworkObjSetDefTransient(virNetworkObjPtr network, bool live); +void virNetworkObjUnsetDefTransient(virNetworkObjPtr network); virNetworkDefPtr virNetworkObjGetPersistentDef(virNetworkObjPtr network); int virNetworkObjReplacePersistentDef(virNetworkObjPtr network, virNetworkDefPtr def); diff --git a/src/libvirt_private.syms b/src/libvirt_private.syms index 1a0c2f6..fd30024 100644 --- a/src/libvirt_private.syms +++ b/src/libvirt_private.syms @@ -872,6 +872,7 @@ virNetworkObjLock; virNetworkObjReplacePersistentDef; virNetworkObjSetDefTransient; virNetworkObjUnlock; +virNetworkObjUnsetDefTransient; virNetworkObjUpdate; virNetworkRemoveInactive; virNetworkSaveConfig; diff --git a/src/network/bridge_driver.c b/src/network/bridge_driver.c index 5578373..fa909a1 100644 --- a/src/network/bridge_driver.c +++ b/src/network/bridge_driver.c @@ -2327,8 +2327,10 @@ networkStartNetwork(struct network_driver *driver, break; } - if (ret < 0) + if (ret < 0) { + virNetworkObjUnsetDefTransient(network); return ret; + } /* Persist the live configuration now that anything autogenerated * is setup. @@ -2388,13 +2390,7 @@ static int networkShutdownNetwork(struct network_driver *driver, } network->active = 0; - - if (network->newDef) { - virNetworkDefFree(network->def); - network->def = network->newDef; - network->newDef = NULL; - } - + virNetworkObjUnsetDefTransient(network); return ret; } -- 1.7.11.7

[libvirt] [PATCH v4 0/4] command line fd passing using fd sets
by Corey Bryant 19 Oct '12

19 Oct '12

This series adds command line file descriptor passing support via a new -add-fd option. This is a follow-on to the existing QMP fd passing support provided in the following patch series: comments.gmane.org/gmane.comp.emulators.qemu/165463 The new -add-fd option is designed to mirror the add-fd QMP option as much as possible.

Commit ba63d8f7d843461f77a8206c1ef9da38388713e5 introduced a bug that makes machines, that don't have either cpuset in <vcpu> or <emulatorpin> specified, fail.

[libvirt] [PATCH] qemu: Set arch to i686 if qemu-system-i386 is found
by Guido Günther 19 Oct '12

19 Oct '12

If we can't probe the architecture from QMP we parse the architecture from the qemu binaries name. This results in the architecture being i386 instead of i686 which then results in QEMU_CAPS_PCI_MULTIBUS being unset which gives a broken qemu command line. This probably didn't show up earlier since most of the time there's also a /usr/bin/qemu around which results in i686 capabilities. --- src/qemu/qemu_capabilities.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/src/qemu/qemu_capabilities.c b/src/qemu/qemu_capabilities.c index 7c391b3..e897f86 100644 --- a/src/qemu/qemu_capabilities.c +++ b/src/qemu/qemu_capabilities.c @@ -2055,6 +2055,8 @@ qemuCapsInitHelp(qemuCapsPtr caps) /* For historical compat we use 'itanium' as arch name */ if (STREQ(tmp, "ia64")) tmp = "itanium"; + else if (STREQ(tmp, "i386")) + tmp = "i686"; } else { uname_normalize(&ut); tmp = ut.machine; -- 1.7.10.4

[libvirt] [PATCH v3 4/4] qemu-config: Add new -add-fd command line option
by Corey Bryant 19 Oct '12

19 Oct '12

This option can be used for passing file descriptors on the command line. It mirrors the existing add-fd QMP command which allows an fd to be passed to QEMU via SCM_RIGHTS and added to an fd set. This can be combined with commands such as -drive to link file descriptors in an fd set to a drive: qemu-kvm -add-fd fd=3,set=2,opaque="rdwr:/path/to/file" -add-fd fd=4,set=2,opaque="rdonly:/path/to/file" -drive file=/dev/fdset/2,index=0,media=disk This example adds dups of fds 4 and 5, and the accompanying opaque strings to the fd set with ID=2. qemu_open() already knows how to handle a filename of this format. qemu_open() searches the corresponding fd set for an fd and when it finds a match, QEMU goes on to use a dup of that fd just like it would have used an fd that it opened itself.

[libvirt] [PATCHv2 00/16] qemu block-commit support
by Eric Blake 19 Oct '12

19 Oct '12

I figured I'd better post this now, while I still iron out the remaining kinks in my SELinux handling (but I'm certainly a lot closer, now that I have libvirt actually identifying which files need the temporary SELinux labels). With this, you can now do things like 'virsh blockcommit $dom $disk --top relative_name --shallow' even when the backing chain refers to an absolute backing file name; the QMP command passed to qemu will have the correct absolute names.

[libvirt] [PATCH] network: Set to NULL after virNetworkDefFree()
by Michal Privoznik 19 Oct '12

19 Oct '12

which frees all allocated memory but doesn't set the passed pointer to NULL. Therefore, we must do it ourselves. This is causing actual libvirtd crash: Basically, when doing 'virsh net-edit' the newDef should be dropped. And the memory is freed, indeed. However, the pointer is not set to NULL but kept instead. And the next duo of calls 'virsh net-start' and 'virsh net-destroy' starts the disaster. The latter one does the same as 'virsh destroy'; it sees that newDef is nonNULL so it replaces def with newDef (which has been freed already as said a few lines above). Therefore any subsequent call accessing def will hit the ground. --- src/conf/network_conf.c | 3 ++- 1 files changed, 2 insertions(+), 1 deletions(-) diff --git a/src/conf/network_conf.c b/src/conf/network_conf.c index 891d48c..0f7470d 100644 --- a/src/conf/network_conf.c +++ b/src/conf/network_conf.c @@ -260,8 +260,9 @@ virNetworkObjAssignDef(virNetworkObjPtr network, return -1; } } else if (!live) { - virNetworkDefFree(network->newDef); /* should be unnecessary */ + virNetworkDefFree(network->newDef); virNetworkDefFree(network->def); + network->newDef = NULL; network->def = def; } else { virReportError(VIR_ERR_OPERATION_INVALID, -- 1.7.8.6

[libvirt] [PATCH] qemu: Always format CPU topology
by Jiri Denemark 18 Oct '12

18 Oct '12

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. --- src/qemu/qemu_capabilities.c | 6 +++--- src/qemu/qemu_command.c | 1 + src/qemu/qemu_domain.c | 4 +++- src/qemu/qemu_driver.c | 3 ++- 4 files changed, 9 insertions(+), 5 deletions(-) diff --git a/src/qemu/qemu_capabilities.c b/src/qemu/qemu_capabilities.c index 985d4de..7c391b3 100644 --- a/src/qemu/qemu_capabilities.c +++ b/src/qemu/qemu_capabilities.c @@ -685,6 +685,7 @@ qemuCapsInitGuest(virCapsPtr caps, nmachines = 0; if (caps->host.cpu && + caps->host.cpu->model && qemuCapsGetCPUDefinitions(qemubinCaps, NULL) > 0 && !virCapabilitiesAddGuestFeature(guest, "cpuselection", 1, 0)) goto error; @@ -781,12 +782,11 @@ qemuCapsInitCPU(virCapsPtr caps, cpu->sockets = nodeinfo.sockets; cpu->cores = nodeinfo.cores; cpu->threads = nodeinfo.threads; + caps->host.cpu = cpu; if (!(data = cpuNodeData(arch)) || cpuDecode(cpu, data, NULL, 0, NULL) < 0) - goto error; - - caps->host.cpu = cpu; + goto cleanup; ret = 0; diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index 9c72c10..9096b3c 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -4100,6 +4100,7 @@ qemuBuildCpuArgStr(const struct qemud_driver *driver, int hasSVM; if (!host || + !host->model || (ncpus = qemuCapsGetCPUDefinitions(caps, &cpus)) == 0) { virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", _("CPU specification not supported by hypervisor")); diff --git a/src/qemu/qemu_domain.c b/src/qemu/qemu_domain.c index 427258d..cbc621f 100644 --- a/src/qemu/qemu_domain.c +++ b/src/qemu/qemu_domain.c @@ -1227,7 +1227,9 @@ qemuDomainDefFormatBuf(struct qemud_driver *driver, if ((flags & VIR_DOMAIN_XML_UPDATE_CPU) && def_cpu && (def_cpu->mode != VIR_CPU_MODE_CUSTOM || def_cpu->model)) { - if (!driver->caps || !driver->caps->host.cpu) { + if (!driver->caps || + !driver->caps->host.cpu || + !driver->caps->host.cpu->model) { virReportError(VIR_ERR_OPERATION_FAILED, "%s", _("cannot get host CPU capabilities")); goto cleanup; diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index adfbfa6..76730c6 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -10180,7 +10180,8 @@ qemuCPUCompare(virConnectPtr conn, if (!driver->caps) { virReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("cannot get host capabilities")); - } else if (!driver->caps->host.cpu) { + } else if (!driver->caps->host.cpu || + !driver->caps->host.cpu->model) { VIR_WARN("cannot get host CPU capabilities"); ret = VIR_CPU_COMPARE_INCOMPATIBLE; } else { -- 1.7.12.4

[libvirt] [PATCH v3 2/4] monitor: Enable adding an inherited fd to an fd set
by Corey Bryant 18 Oct '12

18 Oct '12

qmp_add_fd() gets an fd that was received over a socket with SCM_RIGHTS and adds it to an fd set. This patch adds support that will enable adding an fd that was inherited on the command line to an fd set. Note: All of the code added to monitor_fdset_add_fd(), with the exception of the error path for non-valid fdset-id, is code motion from qmp_add_fd().
