Abstract

A computer implemented method of instantiating an encrypted disk image for a virtualized computer system includes providing a software component executing in a first virtual machine for instantiation in a first hypervisor, the software component invoking a second hypervisor within the first virtual machine; and providing a basic input output system (BIOS) for the second hypervisor, the BIOS being configured to decrypt and load the encrypted disk image to instantiate the virtualized computer system as a second virtual machine in the second hypervisor, and wherein the software component is further configured to migrate the second virtual machine at a runtime of the second virtual machine to the first hypervisor so as to provide a wholly encrypted disk image for the second virtual machine executing in the first hypervisor.
