LXC over ZFS userquota support

I have setup a centos7 guest. I use LXC with ZFS.

My issue is that the software I need to deploy makes use of linux group and user quotas (no support for ZFS quota). I really do not want to use libvirt.

Is it possible to create a ZFS volume that will be seen as EXT4 from the guest (ZVOL) ?

There is an open issue about it: https://github.com/lxc/lxc/issues/2507
