Patent ID: 8719560

Claim:
A method, in a computing device comprising a processor and a memory, for executing a bare metal boot operation for bare metal booting a control program, comprising: booting the computing device to a hypervisor ownership phase of the bare metal boot operation, wherein during the hypervisor ownership phase of the bare metal boot operation a hypervisor is loaded and controls and manages platform hardware of the computing device; booting the computing device, from the hypervisor ownership phase of the bare metal boot operation, to a transition phase of the bare metal boot operation in which the hypervisor releases control and management of the platform hardware of the computing device to the control program; and booting the computing device from the transition phase to a control program ownership phase of the bare metal boot operation in which the control program is in full control and manages the platform hardware, wherein the bare metal boot operation is performed without restarting the computing device.
