A method includes receiving a command to migrate a workload partition from a source machine to a target machine. The source machine and the target machine are communicatively coupled to a first subnetwork and a second subnetwork, respectively. The workload partition has a source network address defined by network addressing of the first subnetwork. The method also includes determining a socket connection providing network communication between the workload partition and a host. The method includes notifying the host that the workload partition is migrating from the source machine to the target machine, wherein in response to the notifying the host is on alert to receive, through a network tunnel communication, an identification of a target network address that is assigned to the workload partition after the workload partition is migrated to the target machine. The workload partition is migrated from the source machine to the target machine.
