Description of problem:

when running any libvirt metric on Virtual machine that is in paused status, by executing Prometheus query the output is empty.

Version-Release number of selected component (4.12.1 - 4.13.0):

How reproducible:
100%

Steps to Reproduce:
1.create a VM > oc create -f examples/vm-cirros.yaml (or any other vm)
2.pause the VM by executing the following command > virtctl pause VM <VM name>
3. wait ~30 seconds
3.run any libvirt metric by executing Prometheus query > example:
oc exec -n openshift-monitoring prometheus-k8s-0 -c prometheus – curl -s
http://127.0.0.1:9090/api/v1/query?query=kubevirt_vmi_cpu_usage_seconds | jq .

Actual results:

oc exec -n openshift-monitoring prometheus-k8s-0 -c prometheus – curl -s http://127.0.0.1:9090/api/v1/query?query=kubevirt_vmi_cpu_usage_seconds | jq .
{
"status": "success",
"data":

{ "resultType": "vector", "result": [] }

Expected results:

oc exec -n openshift-monitoring prometheus-k8s-0 -c prometheus – curl -s http://127.0.0.1:9090/api/v1/query?query=kubevirt_vmi_cpu_usage_seconds | jq .
