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
