I have a mail server (cyrus + spamassassin/clamav) running in a domU
with no problem. Not high load, but a few thousand messages per day.
It's running on an LVM backed partition (though on a different spindle
than my other domU's), and I see virtually no impact on the other
domU's. I suspect the disk IO is a much bigger factor than CPU, and I
would suspect that if you can dedicate a disk to it, then you will be
quite happy, though I don't know how much I benefit from a lvm backed
vbd vs. a file backed one.
