Hi,

I am afraid I need some help to set up networking for
 	qemu-0.9.1 on FreeBSD 7.0-STABLE amd64 .

The only hint for FreeBSD 7.0 I found was
 	http://people.freebsd.org/~maho/qemu/qemu.html

It seems I don't need to kldload bridge, and don't need to set 
any sysctl variables anymore (right?).

I just did (all as root)
         # ifconfig tap create
         # ifconfig bridge create
         # ifconfig bridge0 addm tap0 addm nfe0 up

and get
         # ifconfig -a
           [...]
tap0: flags=8902<BROADCAST,PROMISC,SIMPLEX,MULTICAST> 
metric 0 mtu 1500
         ether 00:bd:63:44:71:00
bridge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> 
metric 0 mtu 1500
         ether 9e:2e:9a:d5:cf:09
         id 00:00:00:00:00:00 priority 32768 hellotime 2 fwddelay 
15
         maxage 20 holdcnt 6 proto rstp maxaddr 100 timeout 1200
         root id 00:00:00:00:00:00 priority 32768 ifcost 0 port 0
         member: nfe0 
flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP>
         member: tap0 
flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP>


As /etc/qemu-ifup (Permissions 755) I use
         #!bin/sh
         ifconfig ${1} 0.0.0.0

Then I try to
 	# qemu Win2k.img -net nic -net tap
 	/etc/qemu-ifup: could not launch network script
 	Could not initialize device 'tap'

Next thing I tried was
 	# qemu Win2k.img -net nic -net tap,fd=0
Now qemu will start (and a lot of strange symbols are running 
across my terminal) but I can't ping anything.

>From Qemu Monitor I get:
 	(qemu) info network
 	vlan0 devices:
 	tap: fd=0
 	ne2000 pci macaddr=52:54:00:12:34:56


Big thanks for your help,


Uli.
