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. 2013-08-21 15:03:35.162+0...

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

Hi, We have upgraded the libvirt version from libvirt-1.0.5 to libvirt-1.0.6-1 on our linux machine. After this upgrade "virsh cpu-stats <domain>" command is not working on our HardWare. *virsh # cpu-stats test error: Failed to retrieve CPU statistics for domain 'test' error: internal error error accessing cgroup cpuacct for vcpu* ** *# cat /proc/cgroups #subsys_name
