Live migration of virtual machines using virtual bridges in a multi-root input-output virtualization blade chassis

A system comprising:

• a chassis configured to receive a first information handling system, a second information handling system, and a plurality of information handling resources including a network information handling resource, each information handling resource received through a slot in the chassis;
• one or more switches configured to virtualize access of the network information handling resource to the first information handling system and the second information handling system, wherein the first information handling system and the second information handling system share the network information handling resource using the virtualized access;
• a first virtual bridge associated with the network information handling resource;
• a virtual machine configured to access the resources of the first information handling system;
• a virtualization environment configured to migrate the virtual machine from the first information handling system to the second information handling system using the first virtual bridge;
• a first virtual function mapping the network information handling resource and the first information handling system;
• a second virtual function mapping the network information handling resource and the second information handling resource;
• and,
• a physical function mapping the network information handling resource and a chassis management controller;
• wherein the first information handling system and the second information handling system are configured to communicate using the first virtual function, the second virtual function, and the first virtual bridge.

A method for managing migration of a virtual machine, comprising:

• accessing a first information handling system and a second information handling system;
• accessing a network information handling resource;
• using one or more switches, virtualizing access of the network information handling resource to the first information handling system and the second information handling system, wherein the first information handling system and the second information handling system share the network information handling resource using the virtualized access;
• accessing a first virtual bridge associated with the network information handling resource;
• accessing a virtual machine configured to access the resources of the first information handling system;
• and
• copying an operational state of the virtual machine from the first information handling system to the second information handling system using the first virtual bridge;
• mapping a first virtual function mapping between the network information handling resource and the first information handling system;
• mapping a second virtual function between the network information handling resource and the second information handling resource;
• mapping a physical function between the network information handling resource and a chassis management controller;
• and
• communicating between the first information handling system and the second information handling system using the first virtual function, the second virtual function, and the first virtual bridge.

An article of manufacture comprising:

• a non-transitory computer readable medium;
• and
• computer-executable instructions carried on the computer readable medium, the instructions readable by a processor, the instructions, when read and executed, for causing the processor to:
• access a first information handling system and a second information handling system;
• access a network information handling resource;
• using one or more switches, virtualize access of the network information handling resource to the first information handling system and the second information handling system, wherein the first information handling system and the second information handling system share the network information handling resource using the virtualized access;
• access a first virtual bridge associated with the network information handling resource;
• access a virtual machine configured to access the resources of the first information handling system;
• copy an operational state of the virtual machine from the first information handling system to the second information handling system using the first virtual bridge;
• map a first virtual function mapping between the network information handling resource and the first information handling system;
• map a second virtual function between the network information handling resource and the second information handling resource;
• map a physical function between the network information handling resource and a chassis management controller;
• and
• communicate between the first information handling system and the second information handling system using the first virtual function, the second virtual function, and the first virtual bridge.
