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>&quot...

...44.326+0000: 17554: warning : qemuSetupCgroupForVcpu:953 : Unable to get vcpus' pids." This may be the root cause of virsh cpu-stats not working. ( seems to be because of CPU pinning issue ) Because of this the VCPU directories are not created for the corresponding domain in "/dev/cgroup_<controller>/machine/<domain>.libvirt-qemu/" and hence the "cpu-stats" command is not working. Please let us know your view on this. We have collected the debug logs, please find the attachment for the same.. Thanks and Regards, Shree Duth Awasthi. On Wed, Aug 21, 2013...

...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 ar...
