I haven't actually tried it, but I suspect mysql will work just fine.
If you're running tuner cards I'm not so sure about mythtv/ivtv/etc -
I'm not sure if those are compatible with any virtualization schemes.
In general the main issue with virtualization tends to be direct
hardware access / device drivers / etc. An app like mysql that just
access files and communicates via IP shouldn't have any issues as long
as you allocate sufficient RAM/CPU/etc. There will be a little
overhead, but nothing horrible.
