Over-engineered to allow non-contiguous indexes.
Free ports of a controller are stored in a virBitmap.
These bitmaps are stored in a hash table, indexed by
the controller index formatted as a string.
Buses are ignored for now, QEMU doesn't seem
to support anything else than .0
For virtconsoles, addresses are reserved silently,
since we don't put those in the XML, but they occupy
virtio-serial ports.
Missing:
auto-adding controllers when all ports are occupied

RFC, since it hashes the string of an integer.
Yeah, out hash tables require pointers, and we don't like to see an
integer taken as a pointer...
However, I like the idea (I mean the whole idea).

I'd say ACK but since this is an RFC I let others to chime in.
