[ovirt-users] Bandwidth problem

Hello Everyone, I have 10Gb connections setup for all the hosts in the cluster, for both management/vm and gluster traffic ( separate network cards ) The problem is that i just cannot pass 1Gb/s traffic between vms ( even between vms running on the same hosts ! - which makes the things more weird... ). Traffic measured by using iperf tool. Is there a way I can check waht could be the problem ? Network card type, vm drivers, any suggestion ? I just do not know where to look for a possible cause. Thank you very much ! Leo -- Best regards, Leo David
