Abstract
Official abstract text for this publication.
A fault tolerant system includes a primary virtual machine that is formed on a primary machine in which a primary hypervisor runs, and is adapted to input virtual interrupt based on an external interrupt from the primary hypervisor to a primary guest OS, and a secondary virtual machine that is formed on a secondary machine in which a secondary hypervisor runs, and is adapted to input the virtual interrupt to a secondary guest OS on the basis of timing information on the virtual interrupt transmitted from the primary virtual machine. The primary virtual machine is adapted to collect operation performance information from the secondary virtual machine, and to configure an operation performance of the primary virtual machine and an operation performance of the secondary virtual machine so that the operation performance of the primary virtual machine becomes equal to the operation performance of the secondary virtual machine.
First claim
Opening claim text (preview).
What is claimed is: 1. A fault tolerant system, comprising: a primary virtual machine, executed by a first CPU, that is formed on a primary machine in which a primary hypervisor runs, and performs the steps of: inputting a virtual interrupt based on an external interrupt from the primary hypervisor to a primary guest OS; transmitting timing information on the virtual interrupt to a secondary virtual machine; transmitting a theoretical value, which represents a period of time…
