Hi Daniel, Thanks for your immidiate reply. The starting of virtual guest was ok on our machine. We are facing this issue while executing the "cpu-stats <domain name>" command. I have collected the debug logs as you suggested and attaching the same. <<libvirt_testing_starting_VG.log >> --> Log collected while starting the virtual guest <<libvirt_testing_cpu_stats.log >> ---> Log collected while executing cpu-stats comamnd <<CLA_new-0.xml >> ---> Domian.xml used for configuration of virtual guest Can you please check and let us know your opinion.

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

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
