Right now the web UI does not expose which host is running a particular VM 
(note to self, we should add this).

So the best way to tell if a VM is running on a particular node is to use 
the virsh list command as follows:

 From the host running the ovirt-appliance:
# virsh -c qemu+ssh:// list

Use the IP address of the node you want to check.  node3 is 50.3, node4 is 
50.4, etc...

If you get errors about known_hosts having offending keys, prune the 
known_hosts file first:
# ssh-keygen -R
# ssh-keygen -R node3.priv.ovirt.org

(This is because the node generates a new ssh key on each boot.  This is 
something we haven't cleaned up yet)

If you don't see your vm name listed in one of the virsh list commands it 
means the VM is not running on any node.  If the UI says it's running, but 
virsh list doesn't confirm it, this is probably a bug. If this is the 
case, please send us the log files in /var/log/ovirt-wui from the 
appliance as they may help us figure out what is not working properly.
