[Qemu-devel] [Bug 1548170] [NEW] qemu-kvm-spice spice server locks up when large user image is set

[Christopher Snowhill]

Public bug reported:

QEMU emulator version 2.0.0 (Debian 2.0.0+dfsg-2ubuntu1.22), Copyright
(c) 2003-2008 Fabrice Bellard

I have QEMU kvm spice installed, running a Windows 10 1511, freshly
installed this morning, using VirtIO root volume, Ethernet, and QXL
graphics through Spice. It successfully installed the latest updates,
and installed Visual Studio 2010 Professional plus Service Pack 1 and
updates.

Upon attempting to configure the following PNG as my account's user
picture in the Settings control panel applet:

https://static.kode54.net/pwywcomm_christopher_8bpp.png

It added successfully, but then I noticed that Windows does not support
alpha blended user pictures, and it blended it against white, so I
quickly replaced it with the following:

https://static.kode54.net/pwywcomm_christopher_blended.png

Upon assigning that, with the other one still in the previous image
buttons, Spice locked up completely. The VM was still running, as
evidenced by a successful Remote Desktop session.

Do I need to replace my entire Qemu setup with a Git or hand built
official version to verify that this isn't Ubuntu's fault?

I know next to nothing about graphic in QEMU but yes, it's worth to check the
lastest release (2.5) or even better the current git master.

This does not appear to happen with 2.5, which I finally got installed
through a full distribution upgrade to the latest beta of the upcoming
LTS release. Of course, now I have another issue I didn’t notice before,
where the Windows VM, which idles at about 20% of a single core most of
the time, ends up using 80-100% of a single core on the host machine in
the qemu-system-x86_64 process, but that’s probably what it was already
doing before.

Were you able to revert the change and get SPICE to unlock, or otherwise
reproduce the issue? Are the two different PNG files sufficient for
reproducing the problem? Does it happen when you switch from one png to
another generically, or only these two?

Looks like it's working out OK for 2.5, but was the problem reproducible
for your ~2.0 version that we can safely say it's now fixed?

[Thomas Huth]

If I get comment #2 right, the spice issue has been fixed sometime
between v2.0 and v2.5, so I'm closing this ticket now. If you still
encounter this issue with the latest version of QEMU (currently v4.0),
feel free to open again (or report a new bug ticket for other issues).

** Changed in: qemu
