What is the trick to get the networking active with the Linaro QEMU emulating a beaglexm running Linaro Alpha 3? ifconfig -a only shows the loopback interface.

I am creating the boot image with:

#!/bin/sh

# Ref: http://snapshots.linaro.org/11.05-daily/linaro-nano/latest/0/images/tar/ # Ref: http://snapshots.linaro.org/11.05-daily/linaro-hwpacks/omap3/latest/0/images...

linaro-media-create \ --rootfs ext3 \ --hwpack-force-yes \ --dev beagle \ --binary ~/Downloads/linaro-natty-nano-tar-20110305-0.tar.gz \ --hwpack ~/Downloads/hwpack_linaro-omap3_20110305-0_armel_supported.tar.gz \ --image_file beagle_sd.img

QEMU is being run with the following options:

#!/bin/sh

DISK=beagle_sd.img

qemu-system-arm \ -nographic \ -M beaglexm \ -m 512 \ -net nic \ -net user,hostfwd=tcp::5555-:22 \ -usb \ -sd ${DISK}

The head of my git tree for the Linaro QEMU (git://git.linaro.org/qemu/qemu-linaro.git) is:

commit c67ccff50fd53723302c47a233f3daec2807cf0d Author: Peter Maydell peter.maydell@linaro.org Date: Fri Mar 4 11:56:20 2011 +0000

Changelog.LINARO: add note about prlimit64 emulation

Add entry to Changelog.LINARO about prlimit64 (a fix added to the 2011.03-0 release at the last minute).

ifconfig -a only shows the following:
