Well, we'd say NetBSD :)

NetBSD apparently has the edge over Linux for speed of virtual disk 
access.

That's what I use, but it's Xen2 only. Our Xen3 doesn't support PCI export 
to DomU, but has other advantages. We don't have things like xm migrate 
yet.

pkgsrc-Q4 at least. On dom0 you aren't going to have too many packages so 
you won't get to play dependency hell if you choose -current.

Yes if you need Xen3. If it's production, then I'd be tempted to stick to 
3.1_STABLE (N.B. _STABLE). -current a bit too much of a moving target for 
me (especially at the moment - hi ad@!).

Yes, feel free to mix as you see fit.

Not really, but make sure you stick to either the release branch of pkgsrc 
or current (nothing any older). I use -current on dom0 and the release 
branch of pkgsrc on domU with which I build up a shared vnd I mount 
read-only across domUs.
