Yes, I am able to get networking to work out of the box (bitbake
core-image-sato, etc.) Internetworking does not work out of the box.

This is accomplished over tun/tap devices - I do not know much about
these virtual networking devices - they have never failed for me :-)

The IP address of the emulated machine is - The IP address
of host machine is

You can not (out of the box) communicate with machines other than the
host machine - so that would included internet etc.

So, if you have an ssh server or a web-server running on the host
machine - you can ssh to the host machine or browse a webpage using
the browser. Alternatively, you can run a proxy server on the build
machine and use it to get to the internet.

You can run ifconfig to see if the network is configured properly on
the emulated machine in the terminal. It should show - if
you do not see this - you do not have networking working.

I can see the tap0 interface on my host at by using ifconfig.
I can also see the eth0 on the qemu machine at
However, my host has an ip of with a AP gateway at
Somehow I need to connect the networks and I'm not sure exactly how to do that so that DNS servers get used and the traffic all flows.
