Add a schema that describes the properties of virtual machine firmware.
Each firmware executable installed on a host system should come with a JSON file that conforms to this schema, and informs the management applications about the firmware's properties.
In addition, a configuration directory with symlinks to the JSON files should exist, with the symlinks carefully named to reflect a priority order. Management applications can then search this directory in priority order for the first firmware executable that satisfies their search criteria. The found JSON file provides the management layer with domain configuration bits that are required to run the firmware binary.

This is not fully clear to me... what is this exactly good for? Is this a way to say how the firmware should be loaded, i.e. via "-bios", "-kernel" or "-pflash" parameter? If so, the term "memory" is quite misleading since files that are loaded via -bios can also end up in an emulated ROM chip.
I threw in "-kernel" because, although it also (usually?) means "memory", I expected people would want it separate.
What platform / scenario actually uses -kernel to load firmware. If you have loaded firmware using -kernel, how do you then load the actual kernel ?
