[Xen-devel] [PATCH 1/2] xen: enable console and disk backend in HVM mode

[<stefano.stabellini@xxxxxxxxxxxxx>]

From: Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>

Initialize the Xen console backend and the Xen disk backend even when
running in HVM mode so that PV on HVM drivers can connect to them.
