I guess we can argue about HOWTO vs WHATIS, but I think if it exists at all in the Xen world it should be described whether or not it works on NetBSD, how to do it if so, and advice not to use it if that's the consensus. I thought PVH was also for domU, to be sort of HVM with PV drivers, but so that the dom0 didn't need to run a (terrifying security wise) qemu. HVM is reported to work badly on some Linux dom0 setups in terms of disk performance, to the point that it is unusable. And our PV in current runs into trouble in current with dom0s that use the version of grant tables we don't. Yes, that's fuzzy which is why it isn't quite in the HOWTO.
