1)Install nfs-kernel-server
1）安装nfs-kernel-server
sudo apt-get install nfs-kernel-server
2)create nfs folder where rootfs will be copied.
2）创建将复制rootfs的nfs文件夹。
mkdir -p /srv/nfs/
chown 1000:1000 /srv/nfs
3)edit the file /etc/exports
3）编辑文件/ etc / exports
/srv/nfs 127.0.0.1(rw,sync,no_subtree_check,all_squash,insecure,anonuid=1000,anongid=1000)
/ srv / nfs 127.0.0.1（rw，sync，no_subtree_check，all_squash，insecure，anonuid = 1000，anongid = 1000）
orif above does not works then try this
上面的orif不起作用然后尝试这个
/srv/nfs 127.0.0.1(rw,sync,no_subtree_check,no_root_squash,insecure)
/ srv / nfs 127.0.0.1（rw，sync，no_subtree_check，no_root_squash，insecure）
4)Run the command as root
4）以root身份运行命令
exportfs -av
exportfs -av
Copy the _install directory that is generated with Busybox build into the NFS share.
将使用Busybox build生成的_install目录复制到NFS共享中。
5)If you are not created rootfs properly follow this post for complete details http://balau82.wordpress.com/2010/04/27/linux-nfs-root-under-qemu-arm-emulator/

6)run
6）运行
qemu-system-arm -M versatilepb -m 128M -kernel zImage -append "root=/dev/nfs nfsroot=10.0.2.2:/srv/nfs/_install rw ip=10.0.2.15::10.0.2.1:255.255.255.0 init=/sbin/init"
qemu-system-arm -M versatilepb -m 128M -kernel zImage -append“root = / dev / nfs nfsroot = 10.0.2.2：/ srv / nfs / _install rw ip = 10.0.2.15 :: 10.0.2.1:255.255.255.0 INIT = / sbin目录/初始化”
