Will Xen 4.3 use upstream QEMU by default ?

Hi folks,
From the roadmap for Xen 4.3 development, Xen 4.3 will use upstream QEMU
(partially done).
So I''d like to confirm the following questions.

1. Will Xen 4.3 really use upstream QEMU by default ? 
 	I have the question because so far the xen.git tree still uses
qemu-xen-unstable by default.

2. If ''yes'' for 1st question, which QEMU upstream will be used
in Xen 4.3 ?
	In xen.git, upstream QEMU URL is "
git://xenbits.xen.org/qemu-upstream-unstable.git".
	but, the repository of pure QEMU upstream is "
git://git.qemu.org/qemu.git".


Best Regards,
     Yongjie (Jay)

Yes, Ian has just resubmitted a patch:

git://xenbits.xen.org/qemu-upstream-unstable.git is the tree that is
going to be used for the 4.3 release. However development should be done
on git://git.qemu.org/qemu.git first, and once the patches are upstream,
backports can be requested to get features and fixes in
git://xenbits.xen.org/qemu-upstream-unstable.git.

Re: Will Xen 4.3 use upstream QEMU by default ?

Can i suggest that this issue should be sorted out first before doing
the final change to qemu-upstream per default?
http://lists.xen.org/archives/html/xen-devel/2013-03/msg00211.html

Cause for somebody who comes new to xen for using vga passthrough,
this would cause some unnecessary confusion..

Is there a Xen related feature which works fine with qemu-upstream-unstable.git
tree but doesn''t work with qemu.git tree?
I found qemu-upstream-unstable.git tree was based on QEMU 1.3.0 release and
only added several bug fix commits after 1.3.0 release.

I don''t think so. If there are, they are probably just bugs introduced
in qemu.git that need to be fixed.

That''s correct.

Last time I tried this the main issue was one completely outside the
source tree: distro package builders weren''t building qemu with xen
support. If this situation changes (let''s hope so), it would be useful
to build xen without building qemu (i.e. build against installed qemu
dev libraries etc.); I don''t know how feasible this is at the moment.

Thanks for the clarification. 
We''re doing some regular testing for upstream Xen on Intel hardware.
We''ll test xen.git with qemu.git tree by default, while in Xen 4.3
release
cycle we''ll test Xen 4.3 with qemu-upstream-unstable.git tree.

That''s great. 
It would be good for xen.org to test both qemu-upstream-unstable.git
and qemu.git too.

My personal TODO list contains an item to add a 
	./configure --with-system-qemu[=PATH]
build option which disables the qemu upstream build and instead uses the
existing distro provided qemu (default /usr/bin/$somethingTBD).

FWIW I would also like to add --disable-qemu-traditional at the same
time.

Of course if someone was to beat me to it I''d be very pleased to review
a patch instead of writing it (especially given that autoconf is
involved ;-))

I should add that I have no idea when I''ll actually managed to get to
