Maintaining a network connection of a workload during transfer

摘要

According to one embodiment of the present disclosure, a method and technique is disclosed for maintaining a network connection during transfer of the workload from a global environment of a logical partition to a workload partition of the logical partition and during any subsequent transfer(s).

主权项

1. A method for transferring a workload, the method comprising:
receiving a request to transfer a running workload from a global environment of a first logical partition to a workload partition of the first logical partition, the first logical partition comprising a virtualized partition of a data processing system, the workload partition comprising a virtualized operating system environment within an instance of an operating system of the first logical partition, wherein the first logical partition comprises a first Internet Protocol (IP) address, the workload having a network connection to a network resource while in the global environment, the network resource communicating with the workload via the first IP address and using a first socket aliased to the first IP address; and responsive to receiving the request:
creating a special socket in the workload partition associated with the workload, the special socket having a second IP address;transferring the running workload from the global environment to the workload partition; andtransferring data associated with the running workload between the network resource and the workload by transferring the data between the first socket and the special socket while the workload is being transferred to maintain the network connection by the network resource to the workload via the first IP address while the workload is being transferred.
