If you're using LXC (lxc-* tools), then you should be able to just
override the bdev option during lxc-create.

But I have a suspicion that you are actually using LXD which works a bit
differently than raw LXC.

If using LXD 2.9 or higher (currently 2.14), then you can create a ZFS
storage pool for those containers that can run on ZFS and a separate
pool that's using a different backend (dir, lvm or btrfs) for your
sql-server containers.


I'm going to guess that you're using Ubuntu 16.04 LTS, if that's the
case and you want to opt-out of the LXD LTS branch (2.0.9 right now) and
opt into the LXD feature branch (2.13 rihgt now), you can do so with:

 - apt install -t xenial-backports lxd lxd-client


At which point you'll be on LXD 2.13 and will be able to use the "lxc
storage" commands to create multiple storage pools using different backends.
