Hello:

The reproducer involves operations not supported in OpenStack. We don't
support manual OVS operations like "ovs-vsctl del-port". Any port
creation/deletion/update should be done via OpenStack API; os-vif
(Neutron in some cases) will be in charge of any operation on the
device, depending on the backend.

Regards.

Title:
  Wrong port status after some operations

Status in neutron:
  Invalid

Bug description:
  The environment is, openstack master branch, all in one devstack, openvswitch agent, dhcp agent.
  After some operations, a nova port turns to wrong status. This issue can be reproduced by following steps:
  1. Remove ovs port from ovs bridge using ovs-vsctl del-port command, neutron port status changed to down, that's right;[1]
  2. Update name of the port, the port turns to ACTIVE status, that's wrong.[2]

  It seems a problem of DHCP provisioning block, when updating port
  name, a DHCP provisioning block was added, then DHCP agent complete
  this provisioning block and make the port ACTIVE.
