[libvirt-users] Information needed regarding the libvirt version libvirt-1.0.6-1

[arun abhinay]

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

Can you let us know if any of the above patches fix our issue.

Thanks
Abhinay
