Makes sense; a PVH Dom0 will speed up any HVM DomU I/O.

Here are the latest numbers.  Except for bwl, k10, glm, these are for PV
NetBSD 8.0.  Older NetBSD guests are all PV for now.


(New measurements come in each night for <= 3 systems (European time

I enabled virtio-net now, was re0 before.  Disk still plain, though.  I
also set TMPDIR to point to a tmpfs, which should significantly reduce
I/O involving qemu.  No data for these changes yet.
