Abstract
Official abstract text for this publication.
A virtual machine monitor (VMM) is configured to enforce deterministic execution of virtual machines in a multiprocessor machine. The VMM is configured to ensure that any communication by physical processors via shared memory is deterministic. When such VMMs are implemented in a distributed environment of multiprocessor machines coupled via a logical communication link, non-deterministic server applications running on virtual machines using the VMM may be replicated.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for enforcing deterministic execution of a thread of a guest operating system (OS) running in a virtual machine (VM) by a virtual machine monitor (VMM) on a host computer having two physical processors, the method comprising: receiving from the guest OS of the VM, by the VM, a first mapping and associated permissions between a virtual address space of the thread of the guest OS and a virtual address space of the VM; installing, by the VM, the firs…
