[PATCH 00/15] RFC xen device model support
Hi all,
this is the long awaited patch series to add xen device model support in
qemu; the main author is Anthony Perard.
Developing this series we tried to come up with the cleanest possible
solution from the qemu point of view, limiting the amount of changes to
common code as much as possible. The end result still requires a couple
of hooks in piix_pci but overall the impact should be very
