Hmmm.

I think this might be better.  Or alternatively, always provide PV,
and have a flag which says `do provide ioemu'.

I think it's very confusing if setting the `type' to `ioemu' rather
than `pv' means `do provide pv but provide ioemu as well'.

Another way of looking at it is: if we wanted to provide some other
interfaces (besides Xen PV and emulated PCI) in the future, would it
be an alternative to PV or to PCI or something additional ?

Ian.
