Abstract
A hypervisor runs on a host computer system and defines at least one virtual machine. An address space of the virtual machine resides on physical memory of the host computer system under control of the hypervisor. A guest operating system runs in the virtual machine. At least one of a host operating system and the hypervisor sets parts of the address space of the host computer system corresponding to parts of the address space of the virtual machine to a locked state in which those parts can be read but not written to.
