community/qemu: Qemu fails to start with error "There is no option group 'spice'"
This bug https://bugs.launchpad.net/qemu/+bug/1910696 shows up in Alpine in version 5.2.0. Comment 2 in the bug above summarizes the problem well. Debian has a workaround for the problem here: https://salsa.debian.org/qemu-team/qemu/-/blob/master/debian/patches/build-most-modules-statically-hack.diff
It would be nice to be able to run LXD on Alpine later than 3.12, but as long as this problem exists, 5.0.0 (in 3.12) seems to be the latest version of qemu that works.
