Infiniband is good for GlusterFS / storage connection but never never 
never never ever use it as a vm network - believe me it's a nightmare.

So you would direct connect your 2 nodes as otherwise you would have to 
buy an Infiniband switch as well (btw I'm not sure if direct connect is 
possible, but I guess it is). Keep in mind that Infiniband cables aren't 
cheap, too.
Why don't you go for 10Gbit/s Ethernet?
