Subject: xen/pvh: Piggyback on PVHVM XenBus.
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=be3e9cf33094210a0723fdc841e1abfd0ddc1007;p=openwrt%2Fstaging%2Fblogic.git

xen/pvh: Piggyback on PVHVM XenBus.

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.
