Depending where and how your guest disks are stored, you would have zfs
for that. At least your dom0 would benefit from zfs (bootenvironments
and frequent snapshotting of all data).
Really easy handling of vlans, bridges and other networking stuff.
(e.g. to configure a nic, you have to plumb it to the system, but you
can use an unplumbed nic for a bridge (what would address your current
No idea so far how well it integrate that all with virt-manager

For udom or smarter dom0 you can use zones.

At all, I would say, you should have a closer look (read a bit at
opensolaris.org) and try it for your own if you are interested.

I have a productive xen running with two osolb134 dom0s with x64-linux,
-windows and -opensolaris as guests.
