libgfapi is a programatic way for qemu to access the volume without the FUSE.
As far as I know , one drawback is that you can't dynamically migrate your VMs from one storage to another.
For oVirt, enabling of libgfapi is a little bit different, as it's activated on Engine's level.

If create more than on brick, like server1:/data1 server1:/data2 n.... would this increate overall performance??Thanks---Gilberto Nunes Ferreira
