Black Screen Linux VM

So, I was installing Fedora Desktop on my iPad (specs below) and I was getting a black screen after starting the VM (this is before anything has been installed, the iso was attached to the VM though). So, I started with virtio-gpu-gl-device and then tried virtio-gpu-gl-pci I also tried virtio-ramfb-gl i also tried virtio-ramfb. I also tried adding a serial device. I even tried the Fedora 38 prebuilt and still the same thing. I installed UTM using Altstore.

* UTM Version: 4.7.5
* OS Version: iPadOS 27 (beta 2)
* Device Model: iPad Air M4 11-inch
* Is it jailbroken (name jailbreak used)? NO
* How did you install UTM? Altstore

The log below is on virtio-gpu-gl-pci:

Reproduce the Fedora 38 ARM VM on the listed iPad configuration with the reported virtio display devices, then inspect the launch log around the display resize request to (0, 0). Done means identifying and resolving the cause of the black screen so the guest display renders; no source file or test is named in the report.
