QEMU/Devices/Network

Network devices are somewhat special, since besides being able to add them the standard way, there's a much easier one to configure them through the -net nic parameter. Also, please note that -device doesn't suppress the default configuration, so it might not do what you intend. Adding a card Simply specifying -net nic on the command line adds an interface. You can select the hardware being emulated using the model modifier. Example: qemu -net nic,model=ne2k_pci ...
