[ovirt-users] How-to create migration network between 3 hosts without switch?

Hi oVirters, I have a network topology: host with two NIC's ports - each host connected with two another hosts.                 host2               /         \ host1  /             \            \              /              \          /                 host3 oVirt can't setup multiple migration networks for cluster. May be possible avoid this or setup some virtual device in shell (like vxvlan) with which oVirt can work? Why we can't use switch at this time? This is 100G "only for migration network" (huge VM's 256GB RAM+) and witch switch price for this setup increased from $3500 to $19000. Thanks, k
