Abstract
A method of managing remote direct memory access (RDMA) to a virtual computing instance includes suspending locally initiated RDMA operations of the virtual computing instance executing on a first host prior to a migration of the virtual computing instance to a second host. The first host includes a first hypervisor and the second host includes a second hypervisor. The method further includes requesting a peer to suspend remotely initiated RDMA operations that target the virtual computing instance through a first channel, establishing after the migration, a second channel between the peer and the second hypervisor that supports execution of the virtual computing instance on the second host, configuring a virtual object of the second hypervisor on the second host to use the second channel for the locally initiated RDMA operations, and requesting the peer to resume the remotely initiated RDMA operations using the second channel.
