[Openstack] [OpenStack]Failed to configure neutron with gre

When I got this error last I had a typo in my neutron.conf file on the
compute node.  this was causing the br-tun not to be created.  I fixed my
typo and then the br-tun showed up like normal and nova-compute ran fine.
 I am sure there are many other scenarios.  turn on debugging for all of
the neutron services on the compute node and check that they are all
running fine.

good luck


    Bridge br-tun
        Port patch-int
            Interface patch-int
                type: patch
                options: {peer=patch-tun}
        Port br-tun
            Interface br-tun

        Port "gre-c0a80a0a"

        Port "gre-c0a80a15"
