Patent ID: 10990690

Abstract:
A computer implemented method of providing whole disk encryption for a virtualized computer system including providing a hypervisor having a data store and instantiating a disk image of the virtualized computer system as a first virtual machine (VM) having a virtual disk from which an operating system of the first VM can be booted; instantiating a second VM in the hypervisor including a software component executing therein, wherein the data store is a shared data store accessible by both the first and second VMs, the method further comprising: the software component accessing the first VM using privileged credentials to install a software agent in the first VM and to replicate the virtual disk of the first VM in the hypervisor data store as a duplicate disk, wherein the software agent is adapted to encrypt data written to, and decrypt data read from, the disk of the first VM at a runtime of the first VM; and the software component encrypting the duplicate disk and unmounting the copied disk and mounting the encrypted duplicate disk in the first VM so as to provide an encrypted disk for the first VM.
