Is that a debug log from when you started the guest, or from
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
