I believe newer versions of lxd:
- keeps the zfs datasets unmounted by default
- only mounts it on the host when container is starting
- unmount it again from the host, so it's only mounted on the container

You should be able to do this on the host:
- zfs list
- zfs mount ...

for example, in my case the dataset name is something
like data/lxd/containers/c1, and it can be mounted (with 'zfs mount')
on /var/snap/lxd/common/lxd/storage-pools/default/containers/c1.
