Well, yes there was a lot of - not exactly custom - hardware in there, but I guess to upgrade the hypervisor they could quite possibly just have replaced the CPU boards. I don't remember any reference to rom-based hypervisors, though ...

From what I recall, the LPARS on IBM or domains on Sun SPARC were managed by firmware loaded from the system board itself, into either a main CPU or a service processor.
