If this is right, I have to change my hotplug patches, but this will be
a mess, because I have no way to tell if a domain is PV or HVM when
plugging in the devices, so if VIF is passed for both PV or PV+TAP I
will have no way of knowing that.
Should we create three different nic types? VIF (PV), IOEMU (TAP),
I think this might be better. Or alternatively, always provide PV,
and have a flag which says `do provide ioemu'.
This looks reasonable given the current types of nic interfaces.
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 ?
I have no idea, could someone shed some light on this?
