Embodiment Construction

[0013] The subject matter of the invention is described herein with specific detail to satisfy statutory requirements. However, the description itself is not intended to limit the scope of this patent. Rather, the inventors contemplate that the claimed subject matter may also be embodied in other ways, to include different combinations of steps similar to those described herein, in conjunction with other present or future technologies.

[0014] Many embodiments of the invention can be implemented on computers. figure 1 And the following discussion is intended to provide a brief general description of a suitable computing environment in which the invention may be implemented. Although not required, the invention will be described in the general context of computer-executable instructions, such as program modules, being executed by a computing device, such as a client workstation or server. Generally, program modules include routines, programs, objects, components, data struct...

Abstract

Disclosed are methods for exposing multiple interfaces of a communications fabric (Ethernet, FibreChannel, Serial-Attached-SCSI, Infiniband, etc.) of a virtual machine and automatically mapping those interfaces onto separate physical interfaces. Such an approach may preserve the simple management experience of a single connection point into the virtual machine while allowing the OS and application within the virtual machine to supply information necessary to efficiently use the multiply underlying physical links.

Description

technical field [0001] The invention relates to computer technology, in particular to virtual machine I / O multipath configuration. Background technique [0002] When a guest computer system is emulated on a host computer system, the guest computer system is called a "virtual machine" because the guest computer system exists on the host computer system only as a software representation that can deviate from the operation of a specific hardware configuration of the native machine middle. The virtual machine presents a simulated hardware configuration to software operating on the virtual machine. [0003] A virtual machine management system (sometimes called a virtual machine monitor, virtualization system, or hypervisor) is also often used to manage one or more virtual machines so that multiple virtual machines can run concurrently on a single computing device. The hypervisor runs directly on the native hardware and virtualizes the machine's resources by presenting the virtu...
