I had been looking at doing the same for a while now. While Gluster is
a great technology and I was very excited by what it could offer, I
don't think Gluster would be suitable for this particular purpose.
Pardon me if I'm wrong but since Gluster works on the file level, I
feel that it isn't really optimal for huge VM images and VM drives.
Any rebuild would require copying entire files and therefore consume
heavy bandwidth and IO.
