The typical use case will be file (no filename quoting issues), i.e.

I'm not a big fan of this syntax because you still end up with not
putting a filename as a single argument.

You can take everything after '=' as-is though, so the parsing/quoting issues are gone nevertheless.

I don't think it extends very
well to other option types either like -net.

Problem with the "-drive.$id.$arg $value" syntax suggested by you is that the qemu option parser can handle fixed -option strings only.

Other ideas?

cheers,
