I was trying to fix slirp but I have given up because the slirp is very 64-bit unfriendly. In fact, it was taken from FreeBSD's src/sys/netinet but it was well before the following commit: http://docs.freebsd.org/cgi/mid.cgi?199808240747.AAA16217 Unfortunately there were too many changes between slirp code fork and this fix. On top of that, the author bastardized mbuf chain, so that we cannot merge this directly. Instead I found this: http://qemu-forum.ipi.fi/viewtopic.php?p=5646&sid=494a2df12b48a1e8fdca8ae0e7bfb752 and re-wrote most of the code: http://people.freebsd.org/~jkim/patch-qemu-pcap.diff The option to use is '-net nic -net pcap' and it should be able to pick up right network interface for you. If not, use '-net nic -net pcap,ifname=<YOUR_NIC_HERE>' instead. But of course, you need access to /dev/bpf*. Modify /etc/devfs.conf or /etc/devfs.rules to set permissions right for you. Downside is host and guest cannot talk directly because it uses bpf(4). And it seems slow for an unknown reason on my FreeBSD/amd64 -CURRENT host. :-( Let me know if anyone knows why. Enjoy, Jung-uk Kim
