My test deployment consits of one api-cell node, one child-cell node and one compute node. api-cell node: nova-api, nova-cells, nova-cert, nova-condoleauth, nova-novncproxy child-cell node: nova-cells, nova-conductor, nova-scheduler compute node: nova-compute I found most deployment example is using nova-network with nova-cells. I want to use neutron. So I had keystone , glance, and neutron-server, neutron-dhcp, neutron-l3 shared between all cells and deployed all on the api-cell node. I encounterd similar problem as described in this bug report https://bugs.launchpad.net/nova/+bug/1348103 When boot a new instance, nova-compute fails to get the network-vif-plugged notification and get time out waiting for the call back. But on the neutron server side, it looks like the notification had been successfully sent and get the 200 response code from nova-api server I had to set vif_plugging_is_fatal = False Then the instnace can be spawned normally I am wondering how people use neutron with nova-cells, is this going to cause any trouble in large scale production deployment.
