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
