Hi all,

I have to install several virtual machines on a server
with 2 x XeonQuad and 32GByte RAM. The Problem
is that I have to run 32bit software on the virtual
machines.

What can I do?
1) Install a 64bit Linux on the server to be able to
use the 32GByte RAM
--> Problem: Can't set up 32bit xen kernel for the
virtual machine on 64bit Server
-----> Solution: Use HVM but this costs too much
performance
-----> Solution: Use 64bit xen kernel and install
32bit rpms? 
                 Does anyone know a good HOWTO on how
to do that. e.g. using setarch or chroot
2) Install a 32bit Linux on the server
-->Problem: Can I access the full 32GByte for the
domUs? 

Thanks,
Jens
