[Qemu-devel] [PATCH 1/2] Allow use of pc machine type (accel=xen) for Xen HVM domains.

[Paul Durrant <paul.durrant@citrix.com>]

Xen HVM domains normally spawn QEMU with a dedicated xenfv machine type. The
initialization code for this machine type can easily be pulled into the
generic pc initialization code and guarded with a test for whether the xen
accelerator options is specified, which is more consistent with the way
other accelerators are used.
