Public bug reported:
In one openstack with multiple neutron-servers behind a haproxy, in bellow use
case, VM can't communicate with others in DVR,
reproduce steps:
1. create a subnet and add this subnet to a DVR
2. bulk create two VMs with a specail compute node(this node does not include
any VMs in this subnet) in this subnet
3. when a VM port status is ACTIVE, but another VM port status is BUILD, delete
the VM which port status is ACTIVE
then I can't find the namespace of this DVR router, the reason is that when it
'delete_port', it will check the the all the ports status in this host and
subnet using 'check_ports_active_on_host_and_subnet', but it check port ACTIVE
status, sometimes a VM's port status will be BUILD
def check_ports_active_on_host_and_subnet(self, context, host,port_id,
subnet_id):
"""Check if there is any dvr serviceable port on the subnet_id."""
filter_sub = {'fixed_ips': {'subnet_id': [subnet_id]}}
ports = self._core_plugin.get_ports(context, filters=filter_sub)
for port in ports:
if (n_utils.is_dvr_serviced(port['device_owner'])
and port['status'] == 'ACTIVE'
and port['binding:host_id'] == host
and port['id'] != port_id):
LOG.debug('DVR: Active port exists for subnet %(subnet_id)s '
'on host %(host)s', {'subnet_id': subnet_id,
'host': host})
return True
return False
