System and Method to Discover Virtual Machines from a Management Controller

摘要

An information handling system includes a processor to run a hypervisor and a management controller coupled to the hypervisor. The management controller includes a virtual Universal Serial Bus (USB) hub, and the hypervisor launches a virtual machine on the processor. In response to an indication from the hypervisor that the virtual machine has been launched, the management controller instantiates a USB virtual NIC coupled to the virtual USB hub, and provides an address of the USB virtual NIC to the hypervisor. The hypervisor provides the address to the virtual machine. The virtual machine provides information to the management controller via the USB virtual NIC.

1. An information handling system comprising:
a processor to run a hypervisor, wherein the hypervisor launches a first virtual machine on the processor; and a management controller coupled to the hypervisor, wherein the management controller includes a first virtual Universal Serial Bus (USB) hub, the management controller configured to provide remote out-of-band management of the information handling system; wherein:
in response to a first indication from the hypervisor that the first virtual machine has been launched, the management controller instantiates a first USB virtual network interface card (NIC) coupled to the first virtual USB hub, and provides a first address of the first USB virtual NIC to the hypervisor;the hypervisor provides the first address to the first virtual machine; andthe first virtual machine provides first information to the management controller via the first USB virtual NIC.
