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.
Thanks
Abhinay

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
