I have hacked bpf(4) to make connection between host and guest. The patch against -CURRENT is here: http://people.freebsd.org/~jkim/bpf_feedback.diff Basically, injected packet is fed back as if it is incoming packet from the interface. To use the hack, you need the following patch for QEMU: http://people.freebsd.org/~jkim/patch-qemu-pcap_feedback.diff The usage is exactly the same as before: http://docs.freebsd.org/cgi/mid.cgi?200702061748.03125.jkim If you use network controller with checksum offloading feature, you have to turn it off to connect between host and guest, i.e., 'ifconfig <YOUR_NIC_HERE> -rxcsum -txcsum' before starting QEMU. Enjoy, Jung-uk Kim
