常用操作
kubectl get vms -o yaml testvm

virtctl start testvm

# Start the virtual machine:
kubectl virt start testvm

# Stop the virtual machine:
kubectl virt stop testvm
Alternatively you could use kubectl patch:

# Start the virtual machine:
kubectl patch virtualmachine testvm --type merge -p \
    '{"spec":{"running":true}}'

# Stop the virtual machine:
kubectl patch virtualmachine testvm --type merge -p \
    '{"spec":{"running":false}}'

kubectl get vmis
kubectl get vmis -o yaml testvm

virtctl console testvm
Disconnect from the virtual machine console by typing: ctrl+].

virtctl stop testvm

kubectl delete vm testvm
