Abstract
Isolating resources of a virtual machine (VM) guest from a host operating system. A computer system receives an acceptance request from a guest partition corresponding to an isolated VM. The acceptance request identifies a guest memory page that is mapped into a guest physical address space of the guest partition, and a memory page visibility class. The computer system determines whether a physical memory page that is mapped to the guest memory page meets the memory page visibility class. The computer system sets a page acceptance indication for the guest memory page from an unaccepted state to an accepted state based on the physical memory page meeting the memory page visibility class.
