[nSLUG] XEN & Heartbeat

We're looking at replacing our web and email servers; hypervisor's intrigue me.
If anyone has experience with this, would it be possible to have two
boxes, call them Left and Right. Both running XEN and configured with
identical virtual machines, with this software:
- Postfix / CYRUS
Email and iFolder would each get their own virtual machines.
Heres the crunch, I think. Could the load be split this way:
- web server
(3 sites and 3 IPs, as each has its own SSL cert)
- FTP (another IP and SSL cert)
- email server
Disk configuration: MIrrored terabyte SATA disks in each box, and
heartbeat keeps them in sync.
(Remember - the two boxes are configured identically, I really just
want to split the load. Our email server is much busier than the web servers.)
Regards - Miles
