Thanks Mark, I am installing now :)

On the subject of hardware, i am looking at the xSeries 336 from IBM
(as discussed already). These have dual xeon's. 1 of the above (to
begin with), 4GB of RAM and RAID1 for the host OS. The AOE EtherDrive
for storage for the domU's (giving the ability to move a domU from
server to server?) - is this overkill?. We also would have our current
2 x Xeon server (custom build), giving 2 servers in total.

These are the domUs that i would want to have:

- apache/php domU
- apache/asp(sun asp) domU
- dbmail/imap/pop domU
- smtp-in/av/spam domU
- smtp-out/av domU (for autheticated clients)
- mysql domU (for apache servers)
- mysql domU (for dbmail and mydns)
- dns (mydns) domU

What would be the best way to spread the domUs across the available servers?
