Each of the VMs is only likely to be running a couple of daemons for 
proof of concept. No load testing or anything like that. Does 
virtualisation in itself consume a significant amount of the server's 
resources? I would probably go for a boot-level virtualisation approach 
rather than running from a user account a la Virtual Box but I haven't 
looked into anything in depth.
