Hmm, that’s a rather unsupported version of LXD so not a whole lot we’ll be able to do with that if it’s a LXD issue, but the error suggests it’s a ZFS problem.

LXD is trying to use a ZFS pool called default, that pool isn’t available on your system at the time LXD is started. What’s backing that pool? A disk, a partition or a loop file?
