QEMU already supports -netdev tap (if you want to use the host Linux networking stack) and -netdev socket (if you just want point-to-point tunneling). The veth driver isn't suitable for QEMU's use case. QEMU is a userspace process that wants to inject/extract Ethernet frames. That's exactly what the tun (tap) driver does. veth is useful for containers where you want a Linux network interface that is handled by the host network stack. Two solutions for point-to-point: 1. Run two guests with -netdev tap. Put the interfaces on a software bridge (see brctl(8)). Or you could also use IP forwarding instead of a bridge if you like. 2. Run two guests with -netdev socket. They send Ethernet frames directly to each other. See the qemu man page for configuration details. Stefan
