virtualbox.org

I am migrating off a SLES11 server running Xen to a 2010 Mac Mini server running Snow Leopard Server. I plan to use Virtual Box to run a couple of Linux VM's on my Snow Leopard Server host. I plan on having these VM's start at OSX boot without logging in. I will really only use the Virtual Box GUI for VM creation then administer the VM's via VNC. Is it best to create a separate user in OSX to run Virtual Box?
