Re: [Xen-users] SPICE with Upstream QEMU and qxl VGA cause Windows BSOD

Dario, George,
would it be possible for somebody to take the information in this thread and create a wiki page with a valid config? I added a TODO entry for the next docs day, in case this doesn't happen before.

Hi all,
       These days I installed xen 4.3 unstable from source and
recompiled qemu upstream  with spice support.
       After xl create , the windows domU started successfully and
spice client can visit the VDI. However, it display blue screen
before entering the windows welcome screen.
       Is it a bug in current upstream qemu support?

Well, the basics of SPICE/qxl support should all be in Xen 4.3. However,
there is a bug triggered by some, well, emulation issues (it's a SSE
instruction emulation and then communication with qemu, there's a thread
on xen-devel about this).

That's why we have that patch in the tree that jacek is talking about.
In fact, the Xorg qxl driver was triggering right that situation,
leading to a crash.

So, officially, SPICE support is _not_ in 4.3, as that bug was
discovered too late in the release cycle. It's on the agenda already for
4.4, though. :-)

Actually, SPICE support is indeed there, it is _only_ qxl support that
was causing the crash and that has been reverted by the said commit.

Sorry for the mixup. :-P
