The cpu-stats command relies on the vCPU cgroups existing. These are
created when the guest starts. So the fact that cpu-stats can't find
the cgroups shows that something failed during startup.


Your log file shows this:

2013-08-22 12:45:44.326+0000: 17554: warning : qemuSetupCgroupForVcpu:953 : Unable to get vcpus' pids.^M

which is the root cause of your problems.

If libvirt can't find the vcpu PIDs, this suggests that your guests are
running using QEMU TCG instead of KVM.
