Thanks Leonardo, with that confirmed:
- not dependent on the guest distribution
- affecting latest upstream
- good logs on the crash
The videos are not needed but nice to proove your case (just as my pre-
analysis of the code path is nice but likely not useful to a developer
that regularly works on that code sections).
Overall this should really be ready for upstreams attention, I added a
Qemu task which will auto mirror this to the Mailing list.
** Also affects: qemu
Importance: Undecided
Status: New
** Changed in: qemu (Ubuntu)
Status: Incomplete => Confirmed
** Information type changed from Private to Public

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:

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.

QEMU from git apparently is fixed, but Ubuntu's version is still
problematic.
Using an Xubuntu 18.04 guest, it's possible to reproduce the crash
using:
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
In less than 20 seconds the guest crash with:

Very interesting, Still not triggering for me :-/
Could you check if the PPA in [1] (with qemu 2.12 planned for Cosmic) already fixes it for you?

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:

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.

Unfortunately it did not work, the error is still the same although it
used the GTK interface this time. The command I used was:
$ qemu-system-x86_64 -vga qxl -enable-kvm -cpu host -smp
cores=2,threads=2 -m 2048 -cdrom xubuntu-18.04-desktop-amd64.iso
I have noticed Ubuntu's QEMU and this QEMU don't have the OpenGL option
enabled, may this be related to the issue?

Yeah we switched to gtk.
With OpenGL which do you mean - the virtgl based support or some other config option?
Since it still fails to reproduce for me, but you already have a self build qemu that is good.
Could you based on this build 2.12 from source as well and confirm that it fails.
If it does you could bisect from 2.12 to master what fixed it so that we can consider that patch.
Otherwise if 2.12 from source in your own build works lets take a look at the build options that you mentioned.

I meant the option --enable-opengl and, for old versions, --enable-gtk-
gl. I know it is required to use virtual machines using Intel GVT-g with
dma-buf, and is a option strangely absent from QEMU configuration from
Ubuntu's build. Without it, virgl fails too, making virt-manager have an
option that does not work (under Spice Display, OpenGL option does not
work).
The 2.12 build does crash when tested. That while loop is pretty
efficient to trigger it. The git version can keep running it for hours
straight with no problem, while the problematic versions crash in
seconds.
As QEMU configuration is a result mixed between packages found
automatically and those manually set by me, here is the configure
command and its results from my QEMU build:
https://paste.ubuntu.com/p/z9vnFdTnkD/
Please note that I had no need to build other targets for my use, so the
configuration is much smaller than the one used by Ubuntu's QEMU.

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:

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.

qxl: fix local renderer crash
Make sure we only ask the spice local renderer for display updates in
case we have a valid primary surface. Without that spice is confused
and throws errors in case a display update request (triggered by
screendump for example) happens in parallel to a mode switch and hits
the race window where the old primary surface is gone and the new isn't
establisted yet.

Nice, thanks Leonardo for the Bisect - lets call upstream Fixed
Committed then (as there is no 2.13 released yet).
For the separate gl discussion feel free to subscribe/chime in on bug
1657409
Currently 2.12 is on its way into Cosmic.
I'll add and test that patch afterwards, it looks small and safe to me.

Bug description:
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.
Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.
Specify the 'raw' format explicitly to remove the restrictions.

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.

- 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:
+ [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.

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.

Hello Leonardo, or anyone else affected,
Accepted qemu into bionic-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/qemu/1:2.11+dfsg-
1ubuntu7.5 in a few hours, and then in the -proposed repository.
Please help us by testing this new package. See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.Your feedback will aid us getting this
update out to other Ubuntu users.
If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-bionic to verification-done-bionic. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-bionic. In either case, without details of
your testing we will not be able to proceed.
Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in
advance!

Thank you for the effort to backport this bug fix, I have tested the
proposed version 2.11.1(Debian 1:2.11+dfsg-1ubuntu7.5) and the crash
when changing resolution is no longer happening. Unfortunately, after
some time (about 10 minutes, much longer than without this fix), the
guest freezes.
I reported that in https://bugs.launchpad.net/qemu/+bug/1787070
I'll change the tag to verification-done-bionic, as this particular
issue was corrected. The other issue still exists in QEMU upstream.

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.

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.
Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.
Specify the 'raw' format explicitly to remove the restrictions.

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.

Running the Bionic ISO like:

Attaching like:
$ vncviewer FullColor=1 AutoSelect=0 10.245.168.42:5921
(alternatives on tigervnc)
Well for me it had "-k de" as well :-)
Then boot into the "try Ubuntu" live CD mode.
There opened a terminal to loop on xrandr.
Running the loop of above in that guest to crash it after a while.

I agree that this particular issue here is fixed as we hoped.
The other one with the freeze did not occur for me, you might open another bug if you have any pointers how we could go on on this.

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.

Arr reading is hard today, you had the other bug open already ... grml
:-)
Never the less - This bug here is fixed in the proposed version and for
now that is the important part.

Status in QEMU:
Fix Released
Status in qemu package in Ubuntu:
Fix Released
Status in qemu source package in Bionic:
Fix Committed
Bug description:
[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.

Title:
qemu-system-x86_64 crashed with SIGABRT when using option -vga qxl
Status in QEMU:
Fix Released
Status in qemu package in Ubuntu:
Fix Released
Status in qemu source package in Bionic:
Fix Released
Bug description:
[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!

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.
Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.

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.
