Determining suitable network interface for partition deployment/re-deployment in a cloud environment

A method of migrating a logical partition (LPAR), comprising:

• determining a configuration of an LPAR having allocated resources residing on a computer and assigned to a first physical port of the computer, the configuration including a label that specifies a first network topology that is provided by the first physical port of the computer;
• identifying a first target physical port with available capacity to service the LPAR, the first target physical port being identified by a port label that matches the label included in the configuration of the LPAR and that specifies a second network topology that is provided by the first target physical port;
• and
• migrating the LPAR from the first physical port to the first target physical port by reassigning the LPAR to the first target physical port.
