I will say that a NetBSD dom0 is damn stable, even -current. I've
used it for a long time.
The only downside is the fact that the version of Xen in NetBSD is
getting a little crusty. Last I checked, it was still on 3.3.x. XCP
1.0.0 which is stable now uses 3.4.2, and let's not even get started
If you can live without the features/enhancements in the newer Xen
versions, then I'd go all for NetBSD as the dom0.
