Mail server inside domU
Hi list

I have my doubts using file backed vbd for a mail server, but I would like to
since it's so easy to maintain and move around.
There's a lot of small files being written all the time and the mail server
currently has 539 users spread over several real domains (domain.tld), is it
complete idiotic to use a file backed vbd for this?

And how does it influence other domUs which isn't running mail server
software?

I'm using a qmail and spamassassin/clamav setup for the mail server.

What are your experiences with mail servers inside domU?

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.
