We don't think it explains the variation, it sounds very much as though
there are two problems, one of performance and one of the estimates
and chances are the root cause of them is not the same thing.

Perhaps I've misunderstood your things...  You said that your OS and
databases are on dedicated drives.  If so then all you need to do is add
an entry in grub.conf on your dom0 root FS that tells it to boot a non-xen
kernel and that the root-FS is the domU drive.
