app-emulation/lxd-2.19 has just been added. After upgrading, are you still affected?
I have been struggling to make LXD work with openrc recently. Something about cgroup namespace hierarchy. Work with systemd though.

I have recently updated both LXC and LXD wiki pages to describe the workaround I had to go through to make LXC and LXD work under both systemd and openrc. At the core, it involved disabling the recently-introduced cgroups v2. Have you tried this?
lxc works just fine on that system, I'll look at disabling cgroups v2 now.
I wonder if upstream has a systemd-only codepath instead of probing for cgroups v2 and that is causing the issue...

Hey, is this still an issue?
I believe some version bump somewhere has fixed this issue, please re-open if you're still having troubles with current versions in the tree.
