[one-users] OpenNebula 3.8 + GlusterFS 3.4

[Jaime Melis]

Hi,

well, I agree with this. Now that there's an upcoming gluster support in
libvirt, and with qemu's integration with libgsapi for qemu-img create,
integrating it for OpenNebula makes a lot of sense.

In particular we could do the same thing we've done for the CEPH
integration, create a new TYPE = "GLUSTER" image type, and generate
specific domain files for that type (using the new 'source
protocol="gluster"'), like we did in this commit:
https://github.com/OpenNebula/one/commit/555da9937bae384b981c7c310334866f576af925

And create a new set of gluster datastore and tm drivers that use qemu-img
create for the creation of images and for the rest of actions (clone, copy,
rename, rm) either a libgfapi wrapper or directly operating in a fuse
mount...

cheers,
Jaime
