[Rdo-list] networking issues on JUNO redhead openstack.

Hi,

Have you checked the security rules to ensure that port 22 (ssh), port
80 (http) and ICMP are all allowed through to the instance? Tose rules
are not enforces in the instance, they're enforced with iptables in the
host.

You might also try to connect to the instance from inside the same
network namespace - just to check that you can.

On the host, as root:
ip netns list
# Identify the network namespace corresponding to your instance
# - look for a qrouter namespace
# - List all of the routes in the namespace
ip netns exec qrouter-1fabd5f0-f80b-468d-b733-1b80d0c3e80f \
  ip r

# ssh into guest
$ ip netns exec qdhcp-4a04382f-03bf-49a9-9d4a-35ab9ffc22ad ssh
cirros@${instance_ip_addr}

This will at least eliminate the possibility that your instance is
somehow broken.

Thanks,
Dave.
