...p" directory created by kenel under "/sys/fs/". We suspect that the 'cgroup' controllers are not mounted properly and hence the issue is observed. While using the libvirt-1.0.5 version below mentioned mount commands were sufficient to mount cgroup controllers *mkdir -p /dev/cgroup_cpuacct mount -t cgroup -o cpuacct cpuacct /dev/cgroup_cpuacct* As cgroups hieracrhy inside libvirtd has changed in libvirt-1.0.6-1, we feel that the above commands are now not sufficient. We feel we have to do some more steps get the 'cgroups' mounted properly on our hardware. Since we are new t...

Hi Daniel, Thanks a lot for your reply. We have mounted all the cgoup controllers at "/dev/cgroup_<controller>" as mentioned below. ls /dev/ | grep cgroup cgroup_cpu cgroup_cpuacct cgroup_cpuset cgroup_mem On further debugging we dound that the "VCPU" directories are not being created for our domains and hence the comamnd "cpu-stats <domain>" is failing. Below is the snippet of logs collected with debug logs enabled for libvirt. 2013-...

Hi Eric, Thanks for your valuable time and comments. >> Are you sure cpuacct was mounted prior to libvirtd starting? Yes, we are mounting cpuacct before starting the libvirtd daemon. >> Libvirt won't mount cgroups; Yes, Agree. >>it only uses what was mounted at the time it was started. But we are mounting it well before it is started. We are facing the issue only while
