Yes - i guess we do!

By user domains, i take it that this is a domU? (sorry - new to this).
If so, we would be looking at 5 user domains. 1: web/ftp 2: dbmail 3:
smtp 4: pop/imap 5: dns on a single server (server1).

I would keep my mysql server as a separate server... but could make
this server a Xen server (server2) as well, with the 1 domU running
mysql. This could also be used to move domU's from sever1 if need be
(fail over?). Thoughts here?

Also, what about backup implications of each domU, how is this best
achieved? A third server to backup all the domU's from each server1
and server2?

Any input is greatly appeicated.
