Tsirkin" , Anthony Liguori , Xen Devel In the context of PV-on-HVM under Xen, the emulated nics are supposed to be unplug before the guest drivers are initialized. This mean that there must be unplug without the consent of the guest. Without this patch, the guest end up with two nics with the same MAC, the emulated nic and the PV nic.
