That will force me to have as many gluster storages as hosts? Or it will allow to have one gluster setup with each of the hosts accessing to the local storage? You will need one volume (with 1 local brick) for each host that needs local storage.
If you need this for many hosts, you could use a script for creating the local volumes. Something like this. HOST=host1 VOL=local-$HOST BRICK=/mnt/disk/gluster-bricks/$VOL mkdir $BRICK *chown vdsm:kvm *$BRICK *gluster vol create $VOL* <localhost>:$BRICK *gluster vol start $VOL *Then *in oVirt engine, you add *this new**storage manually or use the rest API to automate it. Use appropriate volume names referencing the host.
I will investigate, but I'd prefer if I did not have to use any external service at all (in the end, is just local storage) IMO, it's quite easy to setup gluster (2 commands), it is well supported by oVirt and it gives you many benefits you could use in the future like migrating the VM to other host, create snapshots, geo-replicate the storage, etc.
