Yeah, RXE aka. SOFT-RoCE is able to emulate the RDMA, for example
$ sudo rdma link add rxe_eth0 type rxe netdev eth0 # on host
then we can get a new RDMA interface "rxe_eth0".
This new RDMA interface is able to do the QEMU RDMA migration.
Also, the loopback(lo) device is able to emulate the RDMA interface
"rxe_lo", however when
I tried(years ago) to do RDMA migration over this
interface(rdma:127.0.0.1:3333) , it got something wrong.
So i gave up enabling the RDMA migration qtest at that time.
Thanks
