Abstract
An approach is provided in which a migration agent receives a message to migrate a virtual machine from a first system to a second system. The first system extracts hardware state data stored in a native format from a memory area located on first system's network adapter. The hardware state data is utilized by the first system's network adapter to process data packets generated by the virtual machine. Next, the virtual machine is migrated to the second system, which includes copying the extracted hardware state data from the first system to the second system. In turn, the second system configures a corresponding second network adapter by writing the copied hardware state data to a memory located on the second network adapter.
