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

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

when i try a ping it does not return:
# ping -c3 192.168.1.135
PING 192.168.1.135 (192.168.1.135) 56(84) bytes of data.

i tried adding the interface to the bridge br-ex but it didn's work either:
# ip netns exec
89b59bf9f442a0d468d9d4d8c9370c53f8e4a3ba4d8affcd6be8b2dde84fff64
ovs-vsctl add-port br-ex nsbbe59188-ab
relevant log extract:
2014-12-28T22:57:59.577Z|00700|bridge|WARN|could not open network device
nsbbe59188-ab (No such
even with error it appears
# ovs-vsctl list-ports br-ex
eth0
nsbbe59188-ab
i think this is a bridging problem but i'm not sure. can somebody give
me a hint?
Thanks
Ivan
