Hi,

I have few configured VM on openstack and work normally(maybe it's icehouse version.I downloaded it from GIT yesterday).I find that If I delete the VM all,there will be residual ovs-port information on my network node.If I don't manually use neutron-ovs-clear to delete these ovs information,fixed-ip and floating-ip on the new created VM will lose efficacy.Other services on controller node(neutron-server) and compute node(neutron-openvswitch) works well.Is there anyone could tell me why this kind of information always occur and how could I avoid this situation happened again?Any comments would be appreciated.Thx a lot.

This is the outputs on my network node:
