[Qemu-devel] [PULL 4/4] xen_disk: treat "vhd" as "vpc"

[Stefano Stabellini <stefano.stabellini@eu.citrix.com>]

The Xen toolstack uses "vhd" to specify a disk in VHD format, however
the name of the driver in QEMU is "vpc". Replace "vhd" with "vpc", so
that QEMU can find the right driver to use for it.
