RE: [Qemu-devel] problem in ARM nfs boot

[Wessel, Jason]

I suspect the lack of the file system for NFS root is your problem, but
you might consider trying

arm-system-arm -net nic -net tap -kernel zImage -append "root=nfs
nfsroot=192.168.2.182:/myfs,rsize=512,wsize=512"

Personally I just use user mode networking because I like to run
entirely as a user process.  I have even switch ed to user mode NFS as
well.  Let us say you don't have that.  Using the attached patch allows
you to boot with user mode network.

In /etc/exports on the host.
/space  127.0.0.1(rw,no_root_squash,async,insecure,insecure_locks) 

arm-system-arm -kernel zImage -append "ip=dhcp root=/dev/nfs
nfsroot=10.0.2.2:/space/myfs,udp rw console=ttyAMA0"
