I guess that is a good question.

A memory-mapped bus, as I see it, is some kind of bus/network/switch/other interconnect in the hardware that takes memory transactions from a source such as a processor or DMA engine, and delivers them to a recipient based on the address in the transaction.

A memory transaction minimally can be described by its address, value, size, and type (read or write).

A non-memory-mapped bus are not very common in virtual platforms, but I guess you could call something like the CAN bus a non-memory-mapped bus. Or maybe USB and other interconnects that do not directly have memory transactions as their logical interface to the system.
