Cool, thanks a lot. Would have been cool for xm to offer "swap" like

One more question actually, this machine is gonna be a NFS "homes"
server for 30 Linux workstations. The homes are fairly IO busy,
especially when rsnapshot runs :) The question is, would such a
workload be happy to run in a Xen domU or should I be running it as
the dom0 ? I think it makes more sense to use it as the dom0!
I think it does not make a lot of sense to have the host do much more
than manage guests: I suspect that, as far as Linux is concerned, KDE
would rank equally in importance with a XEN guest.
VM, on IBM mainframes, handles this by having all users run their own
virtual machine in which they run their own operating system, whether
CMS for normal interactive use, Linux or one of the other IBM
proprietary operating systems.
On Intellish hardware, XEN Dom0 with just enough OS to run Xen guests
(and do necessary maintenance) is the nearest approximation. VM, in its
various incantations, has been around for about 40 years; Xen and
Intellish/AMDish virtualisation have a way to go to catch up.
