[one-users] Remove VMs stuck in prolog

[Sander Klous]

Hi,
I am testing some modifications in my transfer scripts. Due to some 
mistakes I made in those scripts, VMs are stuck in prolog state. Is 
there a way to force kill them (without deleting the entire database)? 
They are eating up my IP numbers and polluting my onevm list. If I 
delete the database I have to recreate the network and reassign the nodes.
Thanks,
Sander
