<br>
I've installed OpenStack with Docker as hypervisor on a cubietruck, everything<br>
seems to work ok but the container ip does not respond to pings nor respond to<br>
the service i'm running inside the container (nginx por 80).<br>
<br>
I checked how nova created the container and it looks like everything is in place:<br>
<br>

<br>
A funny thing that i noticed but i'm not really sure it's relevant, the docker container<br>
does not show network info when created by nova:<br>
<br>
# docker inspect 89b59bf9f442<br>
<br>

i tried adding the interface to the bridge br-ex but it didn's work either:<br>
<br>

<br>
relevant log extract:<br>
<br>

<br>
<br>
even with error it appears<br>
<br>
# ovs-vsctl list-ports br-ex<br>
eth0<br>
nsbbe59188-ab<br>
<br>
<br>
i think this is a bridging problem but i'm not sure. can somebody give me a hint?<br>
<br>
