This assumes that your guest runs SLES10 as well and has your PV driver packages installed. Only then you can set type=netfront. Otherwise, if you set type=netfront, and your guest does not have PV drivers installed, then your guest will not have any networking device that works... You are assuming that you know what the guest has installed, only then you can set the type=[netfront|ioemu] correctly. In my case though, I don't know what the guest runs, so I would need it to be detected automatically. It works to some extend right now, and it can switch between emulated NIC and PV NIC automatically, if the guest does it properly. However, if the guest does not do it right (on purpose or by mistake), then I suddenly have a guest with two active NICs attached.
