I have successfully installed QEMU to do VGA passthrough. I can get the guest to read the Ubuntu ISO and it will find the img drive I have allocated with

fallocate -l 100G /VMs/VMs/video_gpu.img

The install appears to go fine. When I remove the -drive line with the ISO, I fall to the EFI shell. Some answers have suggested to simply "exit", but I get a BIOS menu, and nothing there seems to help me boot to the drive.

If I proceed to try to reinstall Ubuntu Guest, the installer will detect an existing Ubuntu and will ask to install alongside it.

Did I misconfigure the -drive options below?
