Correct; this part hasn't been implemented yet.  For now, you have to
create volumes outside of libvirt, and libvirt's gluster pool is a
read-only view of what already exists.

Would you like to help write the patches to implement more libvirt
control over the gluster pool?

That URL says that not all pools support all operations.  What would be
really nice is a page like http://libvirt.org/hvsupport.html, except
that it would display storage backends vs. supported storage pool
operations by version.
