Running same VM several times at different guests

Hi. I want to have 250 guests running the same VM. Those are kind of clients. Then I have one server. So clients, as they do all the same, is just executing the same VM on different guests.

I have tried creating one VM, then creating snapshots of its disk, and creating more guest with the lvm snapshots. However, doesn't actually work ( I think it does work but really slowly performance).

Is there a nice way or -best-practice- for doing this??

Thanks!

More info:

If you happen to be using the libvirt toolkit, virt-clone looks like an option:

And someone wrote up a basic HowTo for cloning Xen VMs here:

    Well, I see this post about a cloning script:

    That could be very useful. Let me see if there is a best practice for that situation.
