As the links [1][2] below stated, QEMU development community is currently having some difficulties in maintaining the RDMA migration subsystem due to the lack of resources (maintainers, test cases, test environment etc.) and considering to deprecate it.
According to our user experience in the recent two years, we observed that RDMA is capable of providing higher migration speed and lower performance impact to a running VM, which can significantly improve the end-user's experience during the VM live migration. We believe that RDMA still plays a key role for the QoS and can't yet be replaced by TCP/IP for VM migration at the moment. Jinpu Wang is the upstream maintainer of RNBD/RTRS. He is experienced in RDMA programming, and Yu Zhang maintains the downstream QEMU for IONOS cloud in production. With the consent and supports from Michael Galaxy, who has developed this feature for QEMU, we would like to take over the maintainer's role and create the necessary resources to maintain it further for the community.
