Hi Daniel, Thanks a lot for providing us your pointers. From the domain.xml(attached in my previous mail) which we have used for defining virtual guest i can see below lines <emulator>/usr/local/bin/qemu-system-x86_64</emulator>
We were using same domain.xml in eralier libvirt version and the execution of cpu_stats command was successful. Now if we have to get "cpu_stats" command working using QEMU emulator on libvirt can you suggest what can we do. I have found below links on google while checking for the vcpu pid's error https://www.redhat.com/archives/libvir-list/2013-June/msg00214.htm<https://www.redhat.com/archives/libvir-list/2013-June/msg00214.html> <https://www.redhat.com/archives/libvir-list/2013-June/msg00385.html> https://www.redhat.com/archives/libvir-list/2012-August/msg01405.html https://www.redhat.com/archives/libvir-list/2012-August/msg01413.html Can you let us know if any of the above patches fix our issue.
