Abstract

Official abstract text for this publication.

A next-generation OS with a virtualization feature is executed as a user program on a first virtual processor by selecting, in response to a cause of a call for a host VMM, one of a guest status area ( 221 ) for executing a user program on a second virtual processor and a host status area ( 222 ) for executing the guest VMM, and by updating a guest status area ( 131 ) of a shadow VMCS for controlling a physical processor. Accordingly, without a decrease in performance of a virtual computer, the next-generation OS incorporating the virtualization feature is executed on a virtual server, and the next-generation OS and an existing OS are integrated on a single physical computer.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of providing a plurality of virtual processors, which is carried out by a physical computer including a physical processor and a memory, comprising the steps of: generating, by a first virtual machine manager, a first virtual processor; generating, by a second virtual machine manager executed on the first virtual processor, a second virtual processor; executing, by the second virtual processor, a user program; receiving, by the first virtual m…
