My experiences with Xen dom0 have not been positive. The Hardy xen
flavour is quite difficult to maintain, so we stopped doing custom
binaries (essentially a patch set applied at build time on top of core
sources). I do not foresee us resurrecting dom0 within the standard
kernel package until it is supported upstream.
