Virtualization

We're experimenting with Xen for use in Grid computing where we need to build a gatekeeper machine in front of various HPC clusters to run the various versions of Globus that the different grid projects need, along with development versions. I think we're up to 7 at the moment, assuming there's just a single cluster behind it.

Using Xen means we should be able to run this all on a single box, and so far it's looking pretty solid (i.e. it works and we've not seen a crash, asides from when someone tried something a little brave with LVM snapshots, but that may not have been Xen related).
