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.

Is that a debug log from when you started the guest, or from when you run the cpu-stats command. We need a full log from when you started the guest to try & diagnose this. Run libvirtd with LIBVIRT_LOG_FILTERS="1:cgroup" LIBVIRT_LOG_OUTPUTS=1:file:/tmp/libvirt.log /usr/sbin/libvirtd and start the guest, and then upload the log somewhere we can see it Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :|
