Abstract
Approaches for ensuring the privacy and integrity of a hypervisor. A host operating system manages a set of resources. The host operating system is prevented from accessing a portion of the resources belonging to or allocated by the hypervisor. The host operating system may be prevented from accessing resources belonging to or allocated by the hypervisor by transferring execution of the host operating system into a virtual machine container that does not have sufficient privilege to access any portion of the memory pages in which the hypervisor is executing.
