Claim 18:
19. A method for implementing a replacement of a first hypervisor with a second hypervisor in a computing system, said method comprising:
causing a first hypervisor to initialize a service partition in a computing system, wherein the service partition omits an operating system;
causing the first hypervisor to build a loader block for a second hypervisor in the service partition;
causing the first hypervisor to initialize the second hypervisor within the service partition, the initializing using information included in the loader block;
causing the first hypervisor to synchronize a runtime state of the first hypervisor and the second hypervisor; and
replacing the first hypervisor with the second hypervisor by devirtualizing the second hypervisor from the service partition.
