1. A method of moving remote direct memory access (RDMA) memory from a first node to a second node, comprising: protecting a memory region from write operations, the memory region residing on a first node and including a set of RDMA memory pages, and a list of physical memory pages specifying the set of RDMA memory pages and being associated with a memory handler, wherein the set of RDMA memory pages includes a first memory page; allocating a second memory page, the second memory page residing on a second node; copying data stored in the first memory page to the second memory page; updating the list of physical memory pages by replacing the first memory page specified in the list with the second memory page; and registering the updated list of physical memory pages as RDMA memory, wherein the updated list of physical memory pages is associated with the memory handler after the updated list of physical memory pages is registered.
