| You can by why would you? for a HPC application you normally want as much cpu horse power as you can get, putting more vm's on a single cpu doesn't give you that.
Now i will admit we DO use xen in our HPC environment. We use it for testing scheduling policy without needing a large number of real boxes. We do not currently use xen for production clusters. (we are beowulf style clusters) but at SC last year people were using xen for a type of checkpoint, so they could stop execution of jobs, save the vm to disk (xm save) run a time critical job and restore the saved image.
I just wouldn't do it my self.

Hi.
I'm new to Xen and I would know if it works well in a cluster environment (Beowulf, OpenMosix, CoLinux etc).
I need an HPC running some virtual machines. Is this possible with Xen?
Regards.
