Abstract
Official abstract text for this publication.
A fault-tolerant computer system that includes a computer including a virtual machine on which a guest operating system (OS) is operating and a computer in operation, the computer including a snapshot manager that saves a guest OS snapshot, which includes difference information at each checkpoint, of the guest OS in a memory of the computer, and sends an instruction at each checkpoint to copy the guest OS snapshot as a guest OS snapshot to a memory of a computer via a transfer unit, and that computer includes a snapshot manager that activates a guest OS based on the guest OS snapshot when the computer stops.
First claim
Opening claim text (preview).
What is claimed is: 1. A fault-tolerant computer system including: a first computer that comprises a first memory and a first transfer unit, and operates a virtual machine comprising a guest Operating System (OS); and a second computer that comprises a second memory and a second transfer unit that receives data that is transferred from the first transfer unit, wherein the first computer comprises a first snapshot manager that, together with acquiring a snapshot of the virtual…
