Method and Apparatus for Combined Hardware/Software VM Migration

摘要

A method and apparatus are provided for migrating one or more hardware devices (105) associated with a virtual machine (103) from a source machine (101) to a destination machine (111) by capturing, formatting, storing, and transferring hardware context information from the hardware device(s) at the source machine during the virtual machine migration process using a defined handshake protocol at each associated hardware driver (105) to capture the hardware context information from an associated hardware device (105) being migrated.

1. A method for migrating a hardware machine during virtual machine migration from a source platform to a destination platform, comprising:
identifying a first hardware machine used by a first virtual machine in a source hypervisor on the source platform; retrieving hardware state information from the first hardware machine using a first hardware driver associated with the first hardware machine; transferring the hardware state information to a target hypervisor on the destination platform during migration of the first virtual machine from the source platform to the destination platform; re-establishing the hardware state information at a second hardware machine on the destination platform using a second hardware driver associated with the second hardware machine; migrating the first virtual machine to the target hypervisor on the destination platform; and activating the first virtual machine in the target hypervisor.
