[Qemu-devel] Problems bringing up network in qemu-system-arm

Hi everyone,

I am using the current CVS (HEAD) version of qemu running on x86 linux, 
and am using it to emulate an ARM on the integrator board, running 
arm-linux, using arm-test-0.1.tar.gz.

>From what I've read in this list (
http://lists.gnu.org/archive/html/qemu-devel/2005-12/msg00137.html), it 
should be possible to set up a network, user-mode or TUN/TAP. However, I 
fail to see the light as to how to bring the correct interface up on the 
guest system (arm-linux). ifconfig shows two devices, lo and dummy0, but 
nothing that would point to a smc91 being detected or used. This is 
independent from whether I try -net tap or -net user.

1) Is the network/smc91x support finished enough to be useable?
2) If so, what is the magic bullet? Any boot options that I need to give 
to the kernel? (BTW, I am calling the emulation as

qemu-system-arm -kernel integratorcp.zImage -initrd arm_root.imfg 
-nographic -net user )

Thanks much for any help,
