Abstract
A client hosted virtualization system includes a processor and non-volatile memory with BIOS code and virtualization manager code. The virtualization manager initializes the client hosted virtualization system, authenticates a virtual machine image, launches the virtual machine based on the image, and implements a policy manager. The policy manager determines a policy for the virtual machine, receives a request to access a device from the virtual machine, determines if the virtual machine is permitted to access the device based upon the policy, and if so, permits the virtual machine to access the device. If not, the policy manager denies the virtual machine access to the device. The client hosted virtualization system is configurable to execute the BIOS or the virtualization manager.
