To be more specific, here's what I did: 1. apply kernel module patch - re-insert module 1. QEMU does: ibv_reg_mr(........IBV_ACCESS_GIFT | IBV_ACCESS_REMOTE_READ) 2. Start the RDMA migration 3. Migration completes without any errorsThis test does *not* work with a cgroup swap limit, however. The process gets killed. (Both with and without GIFT)

Are you saying that things worked without actually setting the GIFT flag? In which case why are we adding this flag? - R.
