qemu树莓派桥接网络

下载

2012-12-16-wheezy-raspbian.img

kernel-qemu

由于2012-12-16-wheezy-raspbian.img需要的内核是3.2.27+

cd/lib/modules&&ls

查看

而kernel-qemu提供的内核是3.10.26+

uname-r

查看

完全匹配的没找到，iptables不好使

报

root@raspberrypi:~# iptables -L
libkmod: ERROR ../libkmod/libkmod.c:554 kmod_search_moddep: could not open moddep file ‘/lib/modules/3.10.26+/modules.dep.bin’
iptables v1.4.14: can’t initialize iptables table `filter’: Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

但是不影响使用桥接网络

使用桥接连接qemu中的树莓派到网络

配置脚本放在某处，比如/root/xup

其他设置参考

http://xecdesign.com/qemu-emulating-raspberry-pi-the-easy-way/

[root@localhost qemu]# cat /root/xup   
#!/bin/sh  
/sbin/ifconfig $1 0.0.0.0 promisc up  
/usr/sbin/brctl addif br0 $1  
sleep 2

设置桥接网络

参考http://ju.outofmemory.cn/entry/45837

modprobe tun  
lsmod|grep tun  
ifdown eth0  
ifconfig  eth0 0.0.0.0 promisc up  
brctl addbr br0  
brctl addif br0 eth0  
brctl stp br0 off  
ifconfig br0 192.168.1.55 netmask 255.255.255.0 broadcast 192.158.1.255  
route add default gw 192.168.1.1  
ifup eth0  
启动qemu

[root@localhost qemu]# cat run.sh   
#!/bin/sh  
#qemu-system-arm -kernel kernel-qemu -cpu arm1176 -m 256 -M versatilepb -append "root=/dev/sda2" -hda 2012-12-16-wheezy-raspbian.img -vnc 192.168.1.111:1 -net nic -net user &
