Hi, all,
To start out, I am a programmer, not a Linux administrator. So please
be gentle with me - I'm in over my head here. :)
To start, my setup is: Windows 7 as the base OS with two nics, wired and
wireless (only one active at a time). Under this I have Oracle Virtual
Machine running Ubuntu 4.4.0-38-generic (latest stable release). I have
set up a bridge in Ubuntu's Network Manager as described on
http://ask.xmodulo.com/configure-linux-bridge-network-manager-ubuntu.html.
The bridge is defined as "bridge0" and works correctly in Ubuntu.
I start QEMU under Ubuntu with:
qemu-system-arm -m 1024M \
-sd /export/armhf.qcow2 \
-M vexpress-a9 \
-cpu cortex-a9 \
-kernel /export/boot/vmlinuz \
-initrd /export/boot/initrd.img \
-append "root=/dev/mmcblk0p2" \
-device virtio-net-device,netdev=net0 \
-netdev
bridge,br=bridge0,id=net0,helper=/usr/lib/qemu/qemu-bridge-helper
Guest system is Debian 3.2.0-4-vexpress, again the latest stable
version. I get a SLIRP connection just fine when I don't specify the
-device and -netdev parameters. The "lshw" shows the driver to be
smsc911x, but I don't know how to relate that to which NIC is being
emulated (it at least works).
When I do specify the -device and -netdev parameters, I get no network.
The log shows nothing unusual other than no network device is found.
Are there any known problems with a setup like this? If not, does
anyone have an idea as to what I am doing wrong? I appreciate any and
all suggestions.
Jerry
