When using qemu-system-x86_64 with the option -vga qxl, it crashes. The easiest way to crash it is by trying to change the guest's resolution. However, the system may randomly crash too, not happening only when changing resolution. Here is the terminal output of one of these random crashes:
--------
$ qemu-system-x86_64 -hda /dev/sdb -m 2048 -enable-kvm -cpu host -vga qxl -nodefaults -netdev user,id=hostnet0 -device virtio-net-pci,id=net0,netdev=hostnet0
WARNING: Image format was not specified for '/dev/sdb' and probing guessed raw.

I was running QEMU as a normal user which is on the groups kvm and disk. Initially I supposed the problem was because I was running QEMU as root, but as a normal user this happens too.
I have tested with guests with different Ubuntu version: 18.04, 17.10 and 16.04. It is happening with them all.

[Impact]
* There are conditions where the vga/qxl driver can crash the qemu
process.
* It is like a very complex case of a non initialized var - without the
fix it might try to ask for updates without having a valid primary
surface.
* Backport from upstream https://git.qemu.org/?p=qemu.git;a=commit;h=5bd5c27c7d284d01477c5cc022ce22438c46bf9f to avoid the crash
[Test Case]
* Sometimes booting xubuntu was reported to be enough, at other times it was needed to change resolution a few times to trigger.
# get xubuntu iso (actually other UI Isos should do as well)
$ qemu-system-x86_64 -vga qxl -enable-kvm -cpu host -smp cores=2,threads=2 -m 2048 -cdrom xubuntu-18.04-desktop-amd64.iso
# If it boots successfully, change resolution until it crashes.
$ while true ; do xrandr --output Virtual-0 --mode 640x480 ; sleep 1 ; xrandr --output Virtual-0 --mode 1280x720 ; sleep 1 ; xrandr --output Virtual-0 --mode 1920x1080 ; sleep 1 ; done
* Without the fix that will trigger the qemu crash
[Regression Potential]
* The change "just" adds QXL_MODE_UNDEFINED as one more trigger to leave
the rendering update. That sounds rather safe. But thinking hard on
potential updates I could think of theoretical setups that were in
undefined mode all the time (unlikely or impossible I think) that now
would get no updates anymore. Well I really don't think this is an
issue, but since this section should be open thinking on "potential"
regressions that is what comes to my mind.
[Other Info]
* Thanks to Leonardo for most of the bisecting and discussion work!
