HVM Windows - handover from qemu network drivers to PV network drivers

HVM Windows - handover from qemu network drivers to PV network drivers

[James Harper]

If I understand correctly, a HVM domain's network adapter gets a tapX
device created for it in Dom0 for qemu to talk to, and a vifY.Z device
for the PV drivers (which probably aren't there) to talk to.

How can I stop the qemu code creating the virtual Realtek driver? What
will happen if I try and use PV and Realtek drivers at the same time?
Will the Realtek driver just talk to the tapX interface and the PV
drivers to the vifY.Z interface, and there will be no problems?

Thanks

James

Set the 'type' of the vif to 'ioemu'.

They should be connected up that way, yes. Though, perhaps they will
end up with the same MAC address, which will cause other oddities.
