As someone who recently switched from a Mythbuntu system running other
roles in addition to a backend, I can speak to a couple of benefits:
1. I don't have to worry about the various dependencies my different
apps have breaking other apps.  I can update php, video drivers, etc.,
without worry.
2. I don't have to worry about a configuration for one of my various
web apps messing up MythWeb.
3. If I need to do something that requires a reboot of the backend, I
can just do it without affecting other services.

Additionally, while I've not played with it, there's the potential of
using LVM and snapshots to roll back if an upgrade goes south.


p.s. I will confess that getting my tuner cards working in a
virtualized backend was considerably less straight-forward than a
non-virtualized environment, but I think it's worth it.
