Gosh, this is incredibly verbose for normal command line use. Whilst I can
see it's nice to have fine control over the detail (and bus/device ids) when
you need it, having to write out a command line of that length just to
attach a drive is a real pity.

I could cook up a patch to do something sane with -drive if=ahci as a more
manageable command-line alternative, but is there any chance of this being
accepted if that you're describing the compact syntax as deprecated?

Cheers,

Chris.
