Hi all

We are now three months into 4.6 development window. This is an
email to keep
track of all the patch series I gathered. It is by no means
complete and / or
acurate. Feel free to reply this email with new projects or
correct my
misunderstanding.

*  libxl: add qxl vga interface support for upstream qemu (fair)
    -  Fabio Fantoni
I've been working on SPICE support in the libvirt libxl driver and
quickly came across the lack of support for qxl device.  What is the
status of this work?  AFAICT, there was a v16 posted nearly a year ago
with no comments

http://lists.xen.org/archives/html/xen-devel/2014-05/msg03214.html
After playing with this more, I think the patch will need a
LIBXL_HAVE_QXL or similar in libxl.h.

I noticed this work was committed in the 4.3 dev cycle, but was
reverted
before the release by commit 5479961a, which describes problems with
"instructions that cannot be used for MMIO".  Has any progress been
made
on that front?  Is Fabio's patch the only piece missing to support qxl
devices?
I've tried Fabio's patch on top of fairly recent xen-unstable and don't
see the issues mentioned in the commit message of 5479961a. Note that I
only tried linux HVM guests though.
qxl vga is working good on windows domUs except problem after
save/restore
on linux domUs instead I wasn't able to get it working
today I tried with fedora 22 (beta3) lxde live dvd (have included
latest qxl drivers available): with both stdvga and qxl mouse is
working but not visible and I not understand why, I'll try also
lubuntu 15.04.
can you tell me what dom0 and domU have you use for test please?
dom0 and domU are both SLES12.  Xen is fairly recent xen-unstable plus a
few libxl patches.

Regards,
Jim


But the domU was without qxl driver installed?
With driver installed should always fails with error similar a what I reported FWIK. I mean this: http://lists.xen.org/archives/html/xen-devel/2015-04/txtGtntonxpzb.txt http://lists.xen.org/archives/html/xen-devel/2015-04/msg03064.html Or you have domU with qxl driver installed, used and working? In this case we must find solution or workaround present in SLES12 and apply it also upstream if missed.

Thanks for any reply and sorry for my bad english.
