RDMA Live migration requires registering memory with the hardware, and thus QEMU offers a new 'capability' to pre-register / mlock() the guest memory in advance for higher RDMA performance before the migration begins. This capability is disabled by default, which means QEMU will register the memory with the hardware in an on-demand basis. This patch exposes this capability with the following example usage: virsh migrate --live --rdma-pin-all --migrateuri rdma://hostname domain qemu+ssh://hostname/system Signed-off-by: Michael R.
