Is it possible to create a VM on underlying ZFS storage, and not have the VM format it's disk as ext4 but instead use the zvol directly? Thus avoiding a filesystem on filesystem situation...

Just wondering if this kind of thing makes sense and is possible so ZFS can be put to optimal use.

how would that work with vms? the vm needs some kind of hardware it accesses, not a filesystem

with containers this is the way it works (this is possible because the container and the host share a kernel)
 
Well it's an open question so I don't really know.
You make a valid point that I hadn't considered!

Maybe I should mount a network share for some data by installing samba on the host...
