Hello:
Yesterday I yum update libvirt from 0.9.10 to 0.10.2 ,after update I got some error in libvirtd.log
like this:
2013-05-10 07:39:09.440+0000: 18824: warning : virCgroupMoveTask:885 : no vm cgroup in controller 3
2013-05-10 07:39:09.440+0000: 18824: warning : virCgroupMoveTask:885 : no vm cgroup in controller 4
2013-05-10 07:39:09.440+0000: 18824: warning : virCgroupMoveTask:885 : no vm cgroup in controller 6
so,I restarted cgconfig and libvirtd daemon :
service cgconfig restart ;
service libvirtd restart
after that ,I cannot create snapshot for vm anymore.and error log message below:
2013-05-16 01:13:23.638+0000: 28848: error : qemuDomainSnapshotCreateDiskActive:11299 : internal error Unable to find cgroup for vm1
my version info :
# rpm -q libvirt
libvirt-0.10.2-18.el6_4.4.x86_64
# rpm -q qemu-kvm
qemu-kvm-0.12.1.2-2.295.el6_3.1.x86_64
in /cgroup dir I cannot find anything about vm1.how can I recover the missing cgroup for vm ?
thanks !
