I found out when it was taking 30 min to delete a guest. So, what I can do in a forceful way?

1. How to kill the guest? Can I kill it through virsh or openstack compute service will get sad?

2. What would happen if I stop the compute service?

3. What would happen if I get really annoyed and tell worker node to reboot?
