Hello. I don't find info about how qemu doing live migration via RDAM
- my specific qeustion - does it need ethernet connection for some
info, or can use native RDMA and resolve nodes via GUIDs ?

The entire migration stream is passed over the RDMA; however
I'm not clear how the address lookup works, what you pass to the
migration command is the IP associated with the interface.

Yes i see this. So as i understand working ethernet connection between
nodes needs to be established before live migration. Thanks

I don't think it needs ethernet; it needs an IP address but that
can be IPoIB.
