[Users] Autostarting VMs ?

Hi, I'm new to oVirt and currently just have a single server installed with the allinone setup. All seems to be working well atm, apart from a small gripe about spice consoles not working (out of the box) for non-linux admin consoles. I just have one question that I hope someone on this list might be able to help me with..... How do you configure oVirt to auto-start vms when it starts after a system boot ? I assume that there must be a way for this to happen and I'm just missing a really obvious option right under my nose. Thanks in advance, Rob
