qemu树莓派连接网络
修正死循环启动
输入命令：
nano/etc/ld.so.preload
将会打开一个文件，其中只有一行
/usr/lib/arm-linux-gnueabihf/libcofi_rpi.so
在该行最前列处加上#符号(注意现在是英国式键盘)：
#/usr/lib/arm-linux-gnueabihf/libcofi_rpi.so
如果开始死循环了
使用
qemu-system-arm -kernel kernel-qemu -cpuarm1176 -m 256 -M versatilepb -append “root=/dev/sda2 panic=1 init=/bin/sh rw” -hda 2013-07-26-wheezy-raspbian.img
加了panic=1init=/bin/shrw
扩容
qemu-imgresize2012-12-16-wheezy-raspbian.img+2G
rasp-config
选expand_rootfs
会报错
therewasanerrorrunningdo_expand_rootfs
需要进入树莓派
vi/etc/udev/rules.d/90-qemu.rules
创建文件。
输入内容：
viewplaincopytoclipboardprint?

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
viewplaincopytoclipboardprint?
