Re: virsh create fails with "Unable to find any firmware to satisfy 'efi'" for aarch64 guest on macOS

I am having trouble when I `virsh create test.xml` with an aarch64 guest on a macOS (Apple Silicon) host. I've wrestled with a variety of issues but the one I simply haven't been able to get past is this regarding the UEFI firmware: error: Failed to create domain from test.xml error: operation failed: Unable to find any firmware to satisfy 'efi' This is with `virsh --version` of 7.9.0 and `qemu-system-aarch64 --version` of 6.1.0, both installed via the common `brew` tool from its main 'homebrew/core' tap. I have confirmed that the loader/nvram files referenced do exist. Running `qemu-system-aarch64 -L help` outputs two lines: /opt/homebrew/Cellar/qemu/6.1.0_1/bin/../share/qemu-firmware /opt/homebrew/Cellar/qemu/6.1.0_1/bin/../share/qemu The …/share/qemu-firmware folder does NOT exist, but symlinking it to a …/share/qemu/firmware folder which does exist does not improve the situation. I have also tried renaming the …/share/qemu/firmware folder (e.g. `mv firmware zzz-firmware`) as some notes I found led me to believe that libvirst might ignore my loader/nvram settings entirely if QEMU had the "new" firmware JSON configuration stuff there? But again no improvement…. How can I debug this further? What should I try next? thanks, -natevw
