1. A computing device, comprising:
source mode live migration circuitry configured to participate in a live migration procedure by injecting, into a live migration data package containing a state of a processing unit implementing the source mode live migration circuitry, a signature verifying the state; and
target mode live migration circuitry configured to participate in an additional live migration procedure migrating an additional live migration data package containing an additional state of an additional processing unit by performing an integrity check based on an additional signature, in the additional live migration data package, verifying the additional state.
