You are right, that's our test setup.

The problem I had was that I could't put all the storage nic's in the 
same vlan using the ovirt interface.
But I talked to our networking guy and he said just use an untagged vlan 
instead of trying to put all the storage nics in the tagged vlan.

I have to brush up my networking knowledge. Thanks for replying though.

And thanks to Ayan too, multipath is now working fine.
