Create image server Deployment and Service:

kubectl create -f image-server.yaml -f image-service.yaml

Wait for image-server pod to become Running:

kubectl get pods -w

Create a sample VM:

kubectl create -f cirros-vm.yaml

Wait for cirros-vm pod to become Running:

kubectl get pods -w

List libvirt domains:

./virsh.sh list

Connect to the VM console:

./virsh.sh console $(./virsh.sh list --name)
