Public bug reported:
a net include two subnet,i use this net to create a port , it alway
retrun a fixed ip of one subnet
code:
def _try_generate_ip(context, subnets):
"""Generate an IP address.
The IP address will be generated from one of the subnets defined on
the network.
"""
range_qry = context.session.query(
models_v2.IPAvailabilityRange).join(
models_v2.IPAllocationPool).with_lockmode('update')
for subnet in subnets:
range = range_qry.filter_by(subnet_id=subnet['id']).first()
if not range:
LOG.debug(_("All IPs from subnet %(subnet_id)s (%(cidr)s) "
"allocated"),
{'subnet_id': subnet['id'], 'cidr': subnet['cidr']})
continue
ip_address = range['first_ip']
LOG.debug(_("Allocated IP - %(ip_address)s from %(first_ip)s "
"to %(last_ip)s"),
{'ip_address': ip_address,
'first_ip': range['first_ip'],
'last_ip': range['last_ip']})
if range['first_ip'] == range['last_ip']:
# No more free indices on subnet => delete
LOG.debug(_("No more free IP's in slice. Deleting allocation "
"pool."))
context.session.delete(range)
else:
# increment the first free
range['first_ip'] = str(netaddr.IPAddress(ip_address) + 1)
return {'ip_address': ip_address, 'subnet_id': subnet['id']}
raise n_exc.IpAddressGenerationFailure(net_id=subnets[0]['network_id'])
multiple subnets only return a ip
