thanks for the screenshot, now i know how it should look like. i'm 
attaching my screenshot. i'm missing a couple of elements, especially 
"Cluster Node Type" (i don't have that in my VM cluster either). is 
there an obvious explanation? next step would be to recreate the gluster 
cluster with "clean" oVirt Nodes. maybe my storage hosts are botched, i 
had glusterfs 3.10 packages installed on one of them previously

thanks a lot so far
