RS: [Beowulf] Virtualization in head node ?

[Alan Ward]

I have been working quite a lot with VBox, mostly for server stuff. I agree it can be quite impressive, and has some nice features (e.g. do not stop a machine, sleep it - and wake up pretty fast).

On the other hand, we found that anything that has to do with disk access is pretty slow, specially when working with a local disk image file.

Cheers,
-Alan

I agree re. Virtualbox - I'm evaluating it for desktop use, not for
the purpose suggested here,
and its quite impressive. The latest version offers direct access to
accelerated 3D graphics on the host. Also I put a virtual machine to
sleep yesterday when running a CAD style application, and started it
up later, the application picked itself up mid-stride and continued
on. Well, maybe I'm easily impressed.
