Red herring. This is a warning, and has nothing to do with the actual error (it has since been patched in upstream libvirt).
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
Are you using RHEL? If so, please open a support incident with Red Hat. If not, can you reproduce the problem when you upgrade to libvirt 1.0.5? -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
