Thanks Ronald,
This is my new method ;-) and I can use ping :-)
If any thinks is ok, I can write it in the wiki.

Installing Plan9 network for QEMU (Linux)
Do you need:
* Support for tunneling in kernel, with 802.1q:
tun: "Network device support" -> "Universal TUN/TAP device driver support"
bridging: "Networking options" -> "802.1d Ethernet Bridging"
* The bridge-utils package
First, load the Tunneling kernel support as modules
add "tun" to /etc/modules
Load it now (do not reboot ;-)): modprobe tun
* Create this script:
darky:~# cat kixconf
IFACE=eth0
BRIF=br0
IPORIG=`/sbin/ifconfig $IFACE | grep "inet addr" | cut -d: -f2 | cut -d" "
-f1`
IPGW=`netstat -nr | grep ^"0.0.0.0" | awk -F" " '{print $2} '`
IPBCAST=`/sbin/ifconfig $IFACE | grep "Bcast" | cut -d: -f3 | cut -d" " -f1`
echo "Interface = " $IFACE
echo "Bridge if = " $BRIF
echo "IP = " $IPORIG
echo "Gateway = " $IPGW
echo "Broadcast = " $IPBCAST
ifconfig $IFACE down
brctl addbr $BRIF
ifconfig $IFACE 0.0.0.0 promisc up
ifconfig $BRIF $IPORIG netmask 255.255.255.0 broadcast $IPBCAST up
brctl stp $BRIF off
brctl setfd $BRIF 1
brctl sethello $BRIF 1
brctl addif $BRIF $IFACE
route add default gw $IPGW
darky:~#
Now, configure /etc/qemu-ifup, and set the +x bit (chmod 755 /etc/qemu-ifup)
like this:
darky:~# ls -l /etc/qemu-ifup
-rwxr-xr-x 1 root root 60 2006-08-19 12:57 /etc/qemu-ifup
darky:~# cat /etc/qemu-ifup
#!/bin/sh
ifconfig $1 0.0.0.0 promisc up
brctl addif br0 $1
darky:~#
Now, you can use your Plan9 as a physical node in your network, then
configure the Plan9 scripts as
http://plan9.bell-labs.com/wiki/plan9/Network_configuration/index.html
For boot the Plan 9 you shoud use this command:
/usr/bin/qemu -m 128 -hda '' -net nic,vlan=0,macaddr=00:11:22:33:44:55 -net
tap,vlan=0,ifname= -localtime &
