IMO I would remove the 'type' option from xl.cfg (so that it's
basically ignored) in the ARM case and force it internally to PVH (if
that's the best route for current ARM guests).

What about libvirt users ?  I haven't seen what a libvirt Xen ARM
guest config looks like but we need to meak sure that existing guests
don't break.

For livbirt (or users of libxl library) we could force the type to
pvh, regardless of the value set by the client, but I guess that would
make adding types later on quite complicated.

I am fairly confident we will never have PV guest on Arm. So one solution would be to alias PV to PVH for Arm. This still give us the liberty to add more guest type in the future.

Any opinions?
