Proxmox VE does not support this.
But why you will do this?

I have a specific application that runs within docker thats needs a type of low level filesystem support, d_word I think it was, and zfs FS will not support his but instaling the LXC container into a ZVOL would allow me to install ext4 inside the zvol as part of the 'container vm'

The use ZFS with the DIR storage plugin.
This gives you an ext4 in the CT.
But you lose the snapshot capability.

Why don't you just go with a "real" vm and then ext4 inside? It's still snapshotable, better isolated then lxc and all the glorious PVE features apply fully.

Yes, using a full vm is the route I have taken, as I do not want to give up snapshots.

Thanks for all the advice and replies.
