whatsay guys :) The link sent by one of our luggers a software called xen probably seems to make this a possibility.....!
Actually xen does have some serious people behind it . (HP , Novell, AMD , Red Hat)

Also please note that xen is supposed to be better than vmware as the virtualisation it offers is much closer to pure hardware virtualisation that is offered on big iron machines from companies like IBM.
The only problem is that the guest OS has to be 'ported' to work on xen. The Xen guys apparently managed to get windows running also but couldn't release it due to licensing issues.
