Hello
i am trying to deploy newton via the ansible role to 6 nodes. The
setup-hosts.yml after a while starts giving these errors

i was told this has something to do with bridging , therefore , my
interfaces file is here : http://paste.openstack.org/show/601179/

all hosts have the same interface file listed above with the only
difference the actual host ip .  What could be wrong ?
thank you
