arm开发板如何从虚拟linux上的nfs启动！

zjflinux

启动nfs时打印出如下信息：
IP route cache hash table entries: 1024 (order: 0, 4096 bytes)
TCP established hash table entries: 4096 (order: 3, 32768 bytes)

1:我的bootargs设置是
  bootargs=console=ttySAC0 root=/dev/nfs
   rootnfs=192.168.1.8:/opt/EmbedSky/root ip=192.168.1.6:192.168.1.2:192.168.1.2:255.255.255.0
2:开发板的ip是192.168.1.6  pc上的ip是192.168.1.8 能够互ping
3：我把虚拟机的防火墙关闭
  在虚拟机端输入services iptables stop
4：虚拟机是VMware  + redhat 9 采用nat方式连接网络。其中pc上的本地ip是192.168.1.8虚拟linux上的ip是192.168.245.135
5 :虚拟linux上的nfs服务已开启
6  我不知道为什么我的nfs不能启动！！！！！！！！！！！！！！！

要用bridge, nat 没试过

你有没有设置共享文件夹?
你在虚拟机上自己挂载一下看能否挂上,
