Subject: [PATCH] qemu: fix default devices on sparc machines
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The sparc machines have little in common with sparc64 machines.

No sparc machine type includes a PCI bus, so we should not be adding one
to the XML. This further means that we should not be adding a memory
balloon device, nor USB controller as these are both PCI based.
