I'm instresting with the PVH mode, is there any wiki
available to boot up a PVH guest?
I used the following source code to compile the xen and
dom0.
I have tried adding pvh=1 in xl.cfg file as pv mode, but guest still uses qemu device
model.
If "xl console [domain-name]" gives you the normal PV console, then
you're running in PVH mode. As Roger said, sometimes qemu is used
to provide disk backends even to PV guests.
