verify with build CNV-v4.10.8-37
step:
1. created LimitRange:
$cat limit.yaml
apiVersion: v1
kind: LimitRange
metadata:
  name: resource-limits
  namespace: default
spec:
  limits:
  - default:
      cpu: "2"

    defaultRequest:
      cpu: 100m
      memory: 4Gi
    max:
      cpu: "2"
      memory: 5Gi
    type: Container
2. created a vm with domain.cpu.cores is 10
oc get vm vm-fedora -o yaml 
...
cores: 10
sockets: 1
threads: 1

3: check vmi 
$ oc get vmi vm-fedora -o yaml
...

4: check virt-launcher pod:
$ oc get pods virt-launcher-vm-fedora-spcsp -o yaml
