Regression: no GPU acceleration working in iPadOS 15.1

[Sinemora10]

Setting up the display of my ubuntu VM with any of the Virtio GPU supported cards causes the VM to crash and the iPad to reboot after a purple screen flash. On iPadOS 14.8 it was possible to set virtio-gpu-gl-pci successfully with a significant gain in performance.

• UTM Version: 2.4.1
• OS Version: iPadOS 15.1
• Device Model: iPad pro 11' M1
• Is it jailbroken (name jailbreak used)? No jailbreak, UTM launched with JIT support using Jitterbug
• How did you install UTM? Sideloaded using AltStore

Crash log
If the app crashed, you need a crash log. To get your crash log, open the Settings app and browse to Privacy -> Analytics & Improvements -> Analytics Data and find the latest entry for UTM. You should export the text and attach it here.

Apologies, I cannot see the option in the iPad version of UTM

Debug log
For all issues, including crashes, you should attach a debug log. Open UTM, and open the settings for the VM you wish to launch. Near the bottom of the configuration options (or at the top of the QEMU page) is Debug Log. Turn it on and save the VM. After you experience the issue, quit the VM and re-launch UTM. Open the VM settings again and select Export Log... and attach it here.

Please find attached the log (in this attempt I selected the virtio-gpu-gl-pci (GPU Supported) option, as it used to work on iPadOS 14.8)
debug.log

Upload VM
(Optional) If possible, upload the config.plist inside the .utm. If you do not have this, you can upload the entire .utm but note this contains your personal data. Since GitHub has an attachment size limit, you may want to upload to another service such as Google Drive. Link it here.

Thank you for the log. It shows no QEMU error before your iPad crashes and reboots. As far as I can tell, this a bug in iPadOS / iOS 15.

Thanks Conath. Will continue the discussion in #2743
