With virtual machines, this is easy: the server runs as a guest virtual machine with a network port on the host forwarded to the guest. Every two hours (or whatever), the host runs `kill -9' on the guest -- which is about the same as pulling the plug -- and restarts the guest from a snapshot. I'm reasonably certain this could be done from a cron job with VirtualBox (which is what I use); I'm guessing the other virtualization setups (KVM, Xen, VMWare) can do it too.
