PATCH 0/10: Merge PV framebuffer & console into QEMU
The following series of 10 patches is a merge of the xenfb and xenconsoled
functionality into the qemu-dm code. The general approach taken is to have
qemu-dm provide two machine types - one for xen paravirt, the other for
fullyvirt. For compatability the later is the default. The goals overall
are to kill LibVNCServer, remove alot of code duplication and/or parallel
impls of the same concepts, and

[PATCH 0 of 6 RESEND v2] blktap3/sring: shared ring between tapdisk and the front-end
This patch series introduces the shared ring used by the front-end to pass
request descriptors to tapdisk, as well as responses from tapdisk to the
front-end. Requests from this ring end up in tapdisk''s standard request queue.
When the tapback daemon detects that the front-end tries to connect to the
back-end, it spawns a tapdisk and tells it to connect to the shared ring. The

[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
