Abstract:
1. A method comprising: receiving a command to migrate a workload partition from a source machine to a target machine, the source machine communicatively coupled to a first subnetwork, the target machine communicatively coupled to a second subnetwork, wherein the workload partition has a source network address defined by network addressing of the first subnetwork and used while the workload partition is executing on the source machine; stopping execution of processes executing on the source machine; determining a socket connection providing network communication between the workload partition and a host; 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; encrypting the source network address that is included in the notifying of the host, prior to notifying through the network tunnel communication; migrating the workload partition from the source machine to the target machine; and transmitting, separately from the notifying the host that the workload partition is migrating, scrambler bits from the source machine to the host, wherein the scrambler bits are used to decrypt the target network address.
