Claim:
1. An apparatus comprising: a physical host computer system having at least one processor and a memory; a primary hypervisor executing on the physical host computer system that manages virtual machines on the physical host computer system to provide resources to a user; a host swap hypervisor executing on the physical host computer system that also hosts the primary hypervisor, wherein the host swap hypervisor has a monitor that monitors the primary hypervisor and conditions of the physical host computer system and takes over management of the virtual machines when a failure of the primary hypervisor occurs; wherein the primary hypervisor is reconfigured to become a new host swap hypervisor after a failure of the primary hypervisor and after the host swap hypervisor takes over the management of the primary hypervisor; and wherein the host swap hypervisor takes over management of the virtual machines by redefining the host swap hypervisor with definitions, settings and attributes of the primary hypervisor, allocating necessary resources to the host swap hypervisor to match the primary hypervisor, and re-establishing all the virtual machines that were connected to the primary hypervisor.
