Hello Peter und Zhjian, Thank you so much for letting me know about this. I'm also a bit surprised at the plan for deprecating the RDMA migration subsystem. > IMHO it's more important to know whether there are still users and whether > they would still like to see it around. > I admit RDMA migration was lack of testing(unit/CI test), which led to the a few > obvious bugs being noticed too late. Yes, we are a user of this subsystem. I was unaware of the lack of test coverage for this part. As soon as 8.2 was released, I saw that many of the migration test cases failed and came to realize that there might be a bug between 8.1 and 8.2, but was unable to confirm and report it quickly to you. The maintenance of this part could be too costly or difficult from your point of view. My concern is, this plan will forces a few QEMU users (not sure how many) like us either to stick to the RDMA migration by using an increasingly older version of QEMU, or to abandon the currently used RDMA migration.
