[src/trunk]: src/sys/arch Welcome XENPVHVM mode.
details: https://anonhg.NetBSD.org/src/rev/1aa7ef4fa46f

description:
Welcome XENPVHVM mode.
It is UP only, has xbd(4) and xennet(4) as PV drivers.
The console is com0 at isa and the native portion is very
rudimentary AT architecture, so is probably suboptimal to
run without PV support.
