An approach to optimizing Virtual Machine (VM) migration is provided, the approach involves receiving a request to migrate a first VM from a first server to a second server, selecting a first Input/Output (I/O) virtualization component associated with the first server and a second I/O virtualization component associated with the second server for migrating the first VM, creating a map of network adapters associated with the first and second I/O virtualization components, selecting first network adapters associated with the first I/O virtualization component and second network adapters associated with the second I/O virtualization based, at least in part, on the map of network adapters and sending an indication of the selected first and second I/O virtualization components and the selected first and second network adapters to be used for migrating the first VM.

Input/output component selection for virtual machine migration

Embodiments disclose techniques for migrating a logical partition from a source computing system with an inactive I/O server to another target computing system. In one embodiment, a computing system collects and stores the resource configuration of the logical partition, upon detecting a change in a resource configuration of a logical partition on the source computing system. Once the computing system detects that a I/O server on the source computing system is inactive for a migration of the logical partition, the computing system uses the collected resource configuration to configure the logical partition on the target computing system.
