[libvirt-users] virsh dominfo not returning any stats

[Tony Lin]

Hi there, 
We're running virsh on centos and hit a couple of issues. First instance is cpu.time not incrementing even with the VMs on the hypervisor running a stress tool. After running 'virsh domstats' sometimes it'll go into a state where no output is generated at all. Have anyone seen something like this? We're running a pretty recent build of libvirt. 
# virsh versionCompiled against library: libvirt 3.9.0Using library: libvirt 3.9.0Using API: QEMU 3.9.0RUNNING HYPERVISOR: QEMU 2.9.0
Through the two domstats we see that the cpu.time is not increasing, but vcpu.0.time is not. It's also not reporting a vcpu.0.wait on this centos hypervisor.
