Device Models
-------------
Devices have a *hardware interface* consisting of hardware registers,
interrupts, and so on.

The hardware interface together with the device state representation is called
a *device model*. Device models can be assigned URIs such as
https://qemu.org/devices/e1000e to uniquely identify them.

I think this is a unique identifier, not actually a URI; the https://
isn't needed since no one expects to ever connect to this.

Yes, it could be any unique string. If the URI idea is not popular we
can use any similar scheme.

I'm OK with it being a URI; just drop the https.

I completely agree. https gives the wrong idea about what this represents. Unless you give it https semantics, by requiring a doc or a schema or whatever to be at the URL, but then you enter another universe of cans of worms.
