Actually, by default, Tempest assumes that no backends support it, which 
is why it's disabled by default in Tempest:

https://review.openstack.org/#/c/480746/7/tempest/config.py

And then only enabled by default in devstack if you're using lvm and 
libvirt since at the time those were the only backends that supported it.
