Hi Christian and Robie, apologies for the delay. I have confirmed that the jammy-proposed version 8.0.0-1ubuntu7.1 of libvirt packages fixes this issue for me. Similar to the PPA packages, I tested using the original VM with which I ran into this bug. I confirmed that video was not working with the jammy 8.0.0-1ubuntu7 packages installed. Then I upgraded to 8.0.0-1ubuntu7.1 and re-launched the VM, and video output worked as expected. Finally, I downgraded back to 8.0.0-1ubuntu7 and reproduced the original bug. ** Tags removed: verification-needed verification-needed-jammy ** Tags added: verification-done-jammy -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1972075 Title: Blank screen when viewing GL-accelerated virtio screen on 22.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1972075/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed- jammy to verification-done-jammy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification- failed-jammy. 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 for helping! N.B.

** Description changed:
+ [Impact]
+
+ * New GL handling code in qemu/libs triggers apparmor denials in
+Jammy and later
+
+ * Libvirt already has code that does context aware "if gl is
+ enabled then allow things". The patch extends those by the
+ new paths it needs to access.
+
+ [Test Plan]
+
+ * In your preferred way get a guest of your choice that has UI support,
+for example Ubuntu Desktop
+
+ * Set virtio graphics and Enable GL acceleration.
+Essentially this comes down to those elements:

I recently upgraded from Ubuntu 21.10 to 22.04. I have an existing VM
with virtio video and gl-accelerated Spice display which previously
worked.
After the upgrade, virt-manager and virt-viewer display a blank screen.
In the qemu libvirt logs, I observe many repetitions of:
qemu_spice_gl_scanout_texture: failed to get fd for texture
dmesg contains these AppArmor errors:
[250001.100362] audit: type=1400 audit(1651958128.696:706): apparmor="DENIED"

Modifying the AppArmor config for this VM to permit access to the
`revision` and `config` sysfs paths fixed this issue for me. The VM
display is visible and virgl is working. I was able to do so by adding
the following line:
"/sys/devices/**/{uevent,vendor,device,subsystem_vendor,subsystem_device,config,revision}"

I have submitted the patch upstream to the libvirt mailing list. I don't feel qualified to assert that giving the VM read access to those sysfs files is the right fix, but it did resolve the issue for me. I noticed that GNOME-Boxes bug too while troubleshooting this. I did not try the egl-headless suggestion at the end of the thread, but did attempt to set the env var "MESA_LOADER_DRIVER_OVERRIDE=i965", which still resulted in a blank display for me. It is unclear to me whether the "qemu_spice_gl_scanout_texture: failed to get fd for texture" message is specific to this issue, or if it would occur in a broad class of errors where the graphics fails to initialize. In my case, this is running on an i7-1165G7 Framework laptop with Mesa Intel(R) Xe Graphics (TGL GT2) (0x9a49). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1972075 Title: Blank screen when viewing GL-accelerated virtio screen on 22.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1972075/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Interesting. I did a quick search here and found many reports of other people having this problem (or at least something very similar) in other distros.
