Again this is a quick note to explain myself how to set a kvm (domain/vm) autostart when the server boots up.

To list autostart domains:

virsh list --autostart

To set a domian, e.g. dhcp1, to autostart:

virsh autostart dhcp1

To disable autostart for a domain (e.g. named dhcp1):

virsh autostart dhcp1 --disable
