Abstract
A computer implemented method of providing whole disk encryption for a virtualized computer system including 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 for instantiating a disk image of the virtualized computer system as a second virtual machine, and the software component being configured to install a software agent in the second virtual machine, the software agent being adapted to: a) encrypt the instantiated disk image; b) encrypt data written, by the second virtual machine, to the instantiated disk image at a runtime of the second virtual machine; and c) decrypt data read, by the second virtual machine, from the instantiated disk image at a runtime of the second virtual machine, wherein the software component is 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.
