Abstract
For a process of an operating system, it is detected that a live migration has occurred, the live migration comprising a change in a hardware characteristic of a computer system on which the process executes. A first message is broadcast to a set of processors, the first message causing each processor in the set of processors to enter a waiting state. While each of the set of processors is in the waiting state, a portion of a set of program instructions of the operating system is modified.
