[libvirt] [PATCH] network: prevent infinite hang if ovs-vswitchd isn't running
by Laine Stump 06 Sep '12

06 Sep '12

This fixes https://bugzilla.redhat.com/show_bug.cgi?id=852984 If a network or interface is configured to use Open vSwitch, but ovs-vswitchd (the Open vSwitch database service) isn't running, the ovs-vsctl add-port/del-port commands will hang indefinitely rather than returning an error. There is a --nowait option, but that appears to have no effect on add-port and del-port commands, so instead we add a --timeout=5 to the commands - they will retry for up to 5 seconds, then fail if there is no response. --- I'm not sure if 5 seconds is a reasonable timeout for this, but it seems to work okay for me (in a very lightly loaded environment, but a successful return is always effectively instantaneous...). Unfortunately there doesn't seem to be another way to bound the wait time of ovs-vsctl. :-( src/util/virnetdevopenvswitch.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/util/virnetdevopenvswitch.c b/src/util/virnetdevopenvswitch.c index 764f478..97b9d52 100644 --- a/src/util/virnetdevopenvswitch.c +++ b/src/util/virnetdevopenvswitch.c @@ -105,7 +105,7 @@ int virNetDevOpenvswitchAddPort(const char *brname, const char *ifname, cmd = virCommandNew(OVSVSCTL); - virCommandAddArgList(cmd, "--", "--may-exist", "add-port", + virCommandAddArgList(cmd, "--timeout=5", "--", "--may-exist", "add-port", brname, ifname, NULL); if (virBufferUse(&buf) != 0) @@ -166,7 +166,7 @@ int virNetDevOpenvswitchRemovePort(const char *brname ATTRIBUTE_UNUSED, const ch virCommandPtr cmd = NULL; cmd = virCommandNew(OVSVSCTL); - virCommandAddArgList(cmd, "--", "--if-exists", "del-port", ifname, NULL); + virCommandAddArgList(cmd, "--timeout=5", "--", "--if-exists", "del-port", ifname, NULL); if (virCommandRun(cmd, NULL) < 0) { virReportSystemError(VIR_ERR_INTERNAL_ERROR, -- 1.7.11.4

[libvirt] VM Migration with IEEE802.1Qbh and IEEE802.1Qbg
by Jagath Weerasinghe 05 Sep '12

05 Sep '12

Hi All, Can a VM connected as IEEE802.1Qbh be migrated to a destination host as it were connected as IEEE802.1Qbg? What I wanted to know is, is it possible to change the configuration from IEEE802.1Qbh to IEEE802.1Qbg on the fly? Regards Jagath

[libvirt] [PATCH] Fix adding ports to OVS bridges without VLAN tags
by Kyle Mestery 05 Sep '12

05 Sep '12

The introduction of the new VLAN code, along with the fix from 5e465df6be8bcb00f0b4bff831e91f4042fae272, caused the addition of OVS ports to fail with the following message: ovs-vsctl: 00002|vsctl|ERR|: missing column name This fix takes into account the VLAN arguments are optional, and correctly sets up the command line to run the "ovs-vsctl" command to add ports to the OVS bridge.

[libvirt] [PATCH] qemu: don't pin all the cpus
by Martin Kletzander 05 Sep '12

05 Sep '12

This is another fix for the emulator-pin series. When going through the cputune pinning settings, the current code is trying to pin all the CPUs, even when not all of them are specified. This causes error in the subsequent function which, of course, cannot find the cpu to pin. Since it's enough to pass the correct VCPU ID to the function, the fix is trivial. --- src/qemu/qemu_cgroup.c | 25 +++++++++++++++++-------- 1 file changed, 17 insertions(+), 8 deletions(-) diff --git a/src/qemu/qemu_cgroup.c b/src/qemu/qemu_cgroup.c index 7298e28..5b42793 100644 --- a/src/qemu/qemu_cgroup.c +++ b/src/qemu/qemu_cgroup.c @@ -542,7 +542,7 @@ int qemuSetupCgroupForVcpu(struct qemud_driver *driver, virDomainObjPtr vm) qemuDomainObjPrivatePtr priv = vm->privateData; virDomainDefPtr def = vm->def; int rc; - unsigned int i; + unsigned int i, j; unsigned long long period = vm->def->cputune.period; long long quota = vm->def->cputune.quota; @@ -603,13 +603,22 @@ int qemuSetupCgroupForVcpu(struct qemud_driver *driver, virDomainObjPtr vm) } /* Set vcpupin in cgroup if vcpupin xml is provided */ - if (def->cputune.nvcpupin && - qemuCgroupControllerActive(driver, VIR_CGROUP_CONTROLLER_CPUSET) && - qemuSetupCgroupVcpuPin(cgroup_vcpu, - def->cputune.vcpupin, - def->cputune.nvcpupin, - i) < 0) - goto cleanup; + if (qemuCgroupControllerActive(driver, VIR_CGROUP_CONTROLLER_CPUSET)) { + /* find the right CPU to pin, otherwise + * qemuSetupCgroupVcpuPin will fail. */ + for (j = 0; j < def->cputune.nvcpupin; j++) { + if (def->cputune.vcpupin[j]->vcpuid != i) + continue; + + if (qemuSetupCgroupVcpuPin(cgroup_vcpu, + def->cputune.vcpupin, + def->cputune.nvcpupin, + i) < 0) + goto cleanup; + + break; + } + } virCgroupFree(&cgroup_vcpu); } -- 1.7.12

[libvirt] [PATCH] maint: avoid doubled name in syntax check failures

There still remains an MX query for a plain name with no domain specified that will be forwarded is dnsmasq has --domain=xxx --local=/xxx/ specified.

I'm not sure how special libvirt & qemu are. You could try installing to a local prefix (I sometimes use "./configure --prefix=$HOME/gnu"). Then you have to sort out the environment variables that need setting. I don't think libvirt or libguestfs or qemu document what environment variables should be set to run an internally consistent local copy of the entire libvirt/KVM stack from your home directory. libguestfs has the "./run" script which can be modified. Anyone got any thoughts? I think it is a genuine concern.
