No, it doesn't. I have a setup where the two gluster servers are using 
10G and ovirtmgmt is 1G. We use split-dns but the poor mens variety.
The engine server (mgmt01) sees both gluster servers on its own network 
(192.168.x.x) but the gluster servers itself have host entries for the 
same hostnames in the 172.19.x.x range, same holds for the vmhosts. What 
happens is that you add the storage servers by fqdn and the gluster peer 
probe commands resolve to the 10G network and all storage traffic is 
confined to this network. So managment commands arrive on the 192 
network and the actual work is done on the storage network.

Hope that I haven't confused you beyond hope:-)
