please backport these changes from qemu.git to qemu-xen.git so

Do you mean you want these patches backported from our qemu
to the old ("traditional") xen qemu fork ?
I mean this copy, sorry if the wording was misleading:

Looks like its state is currently at "1.6.2 + something".
Right. I didn't reply but I agree.
I think that we should upgrade qemu-upstream-unstable to QEMU v2.0,
this series:


but I haven't had the time to do it yet.
If nobody does it before, I'll prepare andtest and the qemu 2.0.0 + xen
patches as soon as I have time and I'll post iton github where you can
do a pull.
Or anything else "special" are needed?
No, that would be all.
Make sure to only have these commits on top of v2.0.0:

And please test the updated QEMU with PV (qdisk) and HVM guests.
If everything works as expected, I can just pull your tree.
I had few minutes and I prepared a branch:

git://xenbits.xen.org/people/sstabellini/qemu-dm.git qemu-xen-for-4.5

however your help testing QEMU with HVM and PV guests would still be
very much appreciated and save me a lot of time!
I did some fast tests with pv and hvm domUs (both with qdisk's disks) and I
not found regression for now.

Note: for not add regression in some cases before (or when) push the use of
qemu 2.0 in xen-unstable there must also be this serie: [PATCH 0/2] tools:
update to SeaBIOS 1.7.4
Is the SeaBIOS update actually required to update QEMU?
I am not saying we shouldn't update SeaBIOS but I would like to know if
I have to wait until SeaBIOS has been updated or I can go ahead and
update QEMU now.

I not know if is required but I already saw 4 cases reported by other users here and on debian that had critical regression with hvm domUs using qemu 1.7 or 2.0 with seabios 1.7.3, all solved upgrading seabios to 1.7.4
