Hello,

I migrated a working Centos7/RDO 6 nodes cluster from Liberty to Mitaka. Thanks to coffee and Openstack/RDO migration guides, the cluster migration went fine.

I noticed my Liberty deployed VMs are now running without network. My freshly Mitaka deployed VMs are working.

I can't find any network related errors in nova/neutron log. Debug mode does not show anything strange. The only error is in the network-faulty VM console : http://paste.openstack.org/show/563346/. Mitaka-deployed VMs are fine : http://paste.openstack.org/show/563350/.

Did I missed a VM related migration step ?

Also, network informations is not displayed/available for my Liberty-deployed VMs :
