Re: [libvirt] Can not get domain's cpu time

Hi,
I have a domain running in my KVM box, and try to get its vcpu info by
calling virDomainGetVcpus(), but it seems the cpu time returned to me
is always 0.
And I also found virsh can not get the CPU time too:
$ virsh vcpuinfo aaa
VCPU: 0
CPU: 0
State: running
CPU Affinity: yy
I tried the same virsh command in my Xen box for a running domain, the
output is:
$ virsh vcpuinfo test1
VCPU: 0
CPU: 1
State: running
CPU time: 322.1s <----- I need this
CPU Affinity: yy
As you see, for KVM domain, there is no "CPU time".
But it's very strange that virt-manager can show the right CPU usage
for my running domain, I do not know where virt-manger gets it.
virt-manager only shows the CPU time for the whole guest (virsh dominfo).
Here you are asking for the per-vCPU time, which we've not implemented
for QEMU yet. We should fix this missing support...
