I suspect you either have a misunderstanding of the layering of storage -
or I misunderstood what you plan to achieve.
VM disks are hosted on Gluster and as such, are fairly large files. They
may be sharded for smaller chunks, but these are still pretty big files.
Or are you planning to expose Gluster to the VMs?
