Okay, I've squashed the test together with 2/3 and pushed the series.

Here the commit message mentions a controller, but the code only checks
for the  device,
not for 

Should we forbid that one too? AFAIK we've auto-added it to the XML
only if there was at least floppy.
We need not forbid fdc, as checking for floppy device will fulfill the 
need. Yes, fdc is added only if there was at least one floppy device.




Either way, the series looks good to me.

This prohibits libvirt from creating qemu command with floppy device.

Should we forbid that one too? AFAIK we've auto-added it to the XML
only if there was at least floppy.
