[Qemu-devel] the problem of booting linux kernel from NFS

Hi,All:

I want to boot kernel from NFS, so I compile a kernel supported  NFS &
TUN/TAP device
and change the /etc/qemu-ifup like this:

#!/bin/sh
sudo -p "Password for $0:" /sbin/ifconfig $1 192.168.15.1

when I boot the new kernel, there is the message :
IP-Config: No network device available
Looking up port of RPC 100003/2 on 192.168.15.1

and the kernel cannot mount the root fs.but the kernel has the network
device driver.

What is the reason? and What should I solve it?

the command is :
qemu -net nic -net tap -kernel /usr/src/linux/arch/i386/boot/bzImage  -hda
/dev/zero  -append "ip=192.168.15.110  root=/dev/nfs nfsroot=
192.168.15.1:/scratchbox/users/newbee/targets/ambition"

Thanks

Regards,
HanLiang

The reason that you kernel didn't contain right driver module for your 
network card.

Yes, I just know the reason:
The kernel cannot find the default netcard  ne2k_pci although I have
selected the driver module, when I use other card like rtl8139 or ne2k_isa,
it works well.

By the way, I use ubuntu 7.10 and the kernel is 2.6.22.

Thank you very much
