When attempting to start a virtual machine using a large amount of RAM (e.g. 81,920MB or 65,536MB) on my physical 96GB RAM M2 Max MacBook through UTM, I intermittently receive one of two error messages. Purpose is to build Android OS code.

The first is:
QEMU error: QEMU exited from an error: qemu-aarch64-softmmu: Error: HV_BAD_ARGUMENT

and the second:
QEMU error: QEMU exited from an error: qemu-aarch64-softmmu: -drive if=none,media=cdrom,id=drive6EA5E6A4-0E92-4C50-9C56-405C793F1C8E,file=/Users/aeonitis/Downloads/ubuntu-22.04.2-live-server-arm64.iso,readonly=on: Could not open '/Users/aeonitis/Downloads/ubuntu-22.04.2-live-server-arm64.iso': Operation not permitted.

The issue does not persist when the RAM allocation is set to 32,768MB or less. Everything seems to run fine within that limit.

Additionally, upon inspecting the code, I noticed that the RAMSlider is limited to 32GB maximum. Considering modern Macs now support up to 192GB RAM, I suggest updating this slider for better alignment with the latest hardware capabilities. I stopped troubleshooting past going through the systemMemory variable which might also play a role in this limitation...

Configuration

• UTM Version: 4.3.5
• macOS Version: 13.5
• Mac Chip: M2 Max
• Storage: 300GB
• Cores: 20 out of 24

Sorry I can't provide logs as the folders didn't seem to produce them pre-boot I guess, and for some reason the mac app reporting popup stopped appearing. I'm kinda glad this is the case as I don't wanna share more private device data.
