| |
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 errors
This test does *not* work with a cgroup swap limit, however. The process gets killed. (Both with and without GIFT)
