Based on:

Plus adds support for Ubuntu 24.04 OVMF and seabios firmware locations, and maintains support for both LXD_QEMU_FW_PATH and LXD_OVMF_PATH environmental variables (accepting multiple search paths).

Also changes how apparmor profile is generated to only allow access to specific firmware file selected.

Tested with:

  • Outside of snap on Ubuntu 24.04 with OVMF and Seabios packages.
  • Inside the latest/edge snap, with OVMF and Seabios modes.
  • Upgrading from 5.0/stable snap with VM using 2MB OVMF FW switching to latest/edge with custom binary and check 4MB firmware is used.
  • Inside the latest/edge snap with debug OVMF firmware mode (with/without secureboot enabled).
  • Tested on s390x too.

technicaly correct AAVMF name.
