Generating and managing groups of physical hosts associated with virtual machine managers in an information handling system

An information handling system (IHS) comprising:

• a processor communicatively coupled to a system memory comprising firmware:
• a remote access controller (RAC) communicatively coupled to the processor and to a RAC memory device, the RAC including first firmware executing thereon for attaching and detaching physical hosts to/from virtual machine manager (VMM) host groups associated with a VMS,
• wherein the processor executes the firmware, which configures the processor to:
• determine if any of the physical hosts of a VMM host group are not included in a VMM host list;
• and
• in response to determining that at least one of the physical hosts of the VMM host group is not included in the VMM host list:
• identify the physical hosts of the VMM host group that are not included in the VMM host list;
• and transmit ab indication of the physical hosts of the VMM host group that are not included in the VMM host list to the RAC;
• and
• wherein the first firmware configures the RAC to:
• retrieve, from a controller memory, first identifying data of first target physical hosts that are part of the VMM host group, but not on the VMM host list, wherein the VMM host group comprises all of the physical hosts that are running virtual machines (VMs) that are controlled by the VMM, and wherein the VMM host list is generated by the VMM and contains identifiers for all of the physical hosts that are controlled by the VMM within a networked computing system;
• retrieve second identifying data of second target physical hosts that are part of the VMM host list, but are not part of the VMM host group;
• transmit, to each of the first target physical hosts a request to detach from the VMM host group;
• and
• transmit, to each of the second target physical hosts, a request to attach to the VMM host group.

A virtual machine manager (VMM) host group system for a network of information handling systems (IHSs) comprising:

• a processor communicatively coupled to a system memory comprising firmware;
• a remote access controller (RAC) communicatively coupled to the processor and to a RAC memory device, the RAC including first firmware executing thereon for generating host groups;
• wherein the processor executes the firmware, which configures the processor to:
• determine if any of the physical hosts of a VMM host group are not included in a VMM host list;
• and
• in response to determining that at least one of the physical hosts of the VMM host group is not included in the VMM host list:
• identify the physical hosts of the VMM host group that are not included in the VMM host list;
• and transmit an indication of the physical hosts of the VMM host group that are not included in the VMM host list to the RAC;
• and
• wherein the first firmware configures the RAC to:
• retrieve, from a controller memory, first identifying data of first target physical hosts that are part of the VMM host group associated with a VMM Put not on DB the VMM host list,
• wherein the VMM host group comprises all of the physical hosts that are running virtual machines (VMs) that are controlled by the VMM, and wherein the VMM host list is generated by the VMM and contains identifiers for all of the physical hosts that are controlled by the VMM within a networked computing system;
• retrieve second identifying data of second target physical hosts that are part of the VMM host list, but are not part of the VMM host group;
• transmit, to each of the first target physical hosts, a request to detach from the VMM host group;
• and
• transmit, to each of the second target physical hosts, a request to attach to the VMM host group.
