[ovirt-users] Migration Failure Due to network

Here are the two Events I can see : Host Hypervisor has network interface which exceeded the defined threshold [95%] (em1: transmit rate[98%], receive rate [4%]) Migration failed (VM: Clone-ubuntu, Source: Hypervisor, Destination: hypervisor22). Any ideas ? It it not the first time I have this kind of network saturation issue... My current temporary setup is this : 2 hosts with only one network physical interface used and assigned to ovirtmgmt, used by all VM. Do migration of a running VM from one host to the other use the network assigned to that VM for migration ? Or does it use ovirtmgmt in all cases ? What minimum network architecture setup would you advice me to avoid this kind of issues ?
