I'm trying get dashboard working (using nova.sh) and I'm getting same
problem as Mauricio, compute is not running and after trying manually
run it I've got:

However virsh -c qemu:///system works, so I think is a problem with
libvirt and I think there was an issue about libvirt version under
virtual machines (I'm running all under vm), am I right?
