[Openstack] OpenStack networking and disks...

Hi,

Yes, I didn't reviewed all the features of cinder since it's just 
recently installed. I'm using it for serving LVM volumes from different 
machines. Works great.

But I cannot install anything on this NAS, and therefore it has not 
cinder support. Just plain iscsi support. Even the tgt manager cannot be 
modified.

Maybe I can find a way. But not just now. And manufacture will not 
support it, since it's very lowend. And as they said "There are too many 
fishes on this sea".

Thank you for the advise.
