[Xen-devel] [PATCH v13 18/19] xen/pvh: Piggyback on PVHVM XenBus.

[Konrad Rzeszutek Wilk <konrad.wilk@xxxxxxxxxx>]

From: Mukesh Rathor <mukesh.rathor@xxxxxxxxxx>

PVH is a PV guest with a twist - there are certain things
that work in it like HVM and some like PV. For the XenBus
mechanism we want to use the PVHVM mechanism.
