Please provide a clear description of problem this feature solves
Some bmc-mock hardware models return fixed InfiniBand GUIDs. H100 GUIDs repeat across hosts, while GB200 models can repeat GUIDs within a single host.
UFM and NICo identify ports by GUID. Duplicate values prevent simulated ports from being represented accurately and make discovery ambiguous when real and simulated fabrics coexist.
Feature Description
When machine-a-tron creates an IB-capable host, its simulated hardware shall report a deterministic GUID that is unique for every IB interface across all simulated hosts.
Describe your ideal solution
Derive each GUID from stable per-host data, such as the host serial or allocated hardware address range, plus the interface index.
Implement GUID generation in the relevant bmc-mock hardware models so Redfish discovery and machine-a-tron observe the same values. Preserve the expected 64-bit hexadecimal representation.
