Before I file a bug report - that's how it works for me - /var/lib/lxd/ 
is a symbolic link to /srv/lxd, placed on a btrfs filesystem:

# ls -l /var/lib/lxd
lrwxrwxrwx 1 root root 8 Jun  5 10:15 /var/lib/lxd -> /srv/lxd

# mount|grep /srv
/dev/sda4 on /srv type btrfs 
(rw,noatime,device=/dev/sda4,device=/dev/sdb4,compress=zlib)


# lxc launch images:ubuntu/trusty/amd64 test-image
Creating container...done
Starting container...done
error: exit status 1

Note that it errored when trying to start the container - I have to add 
"lxc.aa_allow_incomplete = 1"; otherwise, it won't start (is there some 
/etc/lxc/default.conf equivalent for lxd, where this could be set?).

However, the container is already created in a directory, so I don't 
think the above error matters:

# btrfs sub list /srv|grep lxd
# btrfs sub list /srv|grep test-image
#
