Spawn on XenAPI fails if the cidr_v6 field in the networks table is null.
Error caught with:
--use_ipv6=False
--network_manager=nova.network.FlatManager
When the use_ipv6 flag is false NetworkManager.create_networks does not populate the cidr_v6 field:
if(FLAGS.use_ipv6):
cidr_v6 = "%s/%s" % (fixed_net_v6[start_v6],
significant_bits_v6)
net['cidr_v6'] = cidr_v6
project_net_v6 = IPy.IP(cidr_v6)
net['gateway_v6'] = str(project_net_v6[1])
net['netmask_v6'] = str(project_net_v6.prefixlen())
However, when network info are fetched by _get_network_info (called by _spawn_with_disk), it is assumed cidr_v6 is always not null:
def ip6_dict(ip6):
return {
--> "ip": utils.to_global_ipv6(network['cidr_v6'], <--
instance['mac_address']),
"netmask": network['netmask_v6'],
"gateway": network['gateway_v6'],
"enabled": "1"}
info = {
'label': network['label'],
'gateway': network['gateway'],
'mac': instance.mac_address,
'rxtx_cap': flavor['rxtx_cap'],
'dns': [network['dns']],
'ips': [ip_dict(ip) for ip in network_IPs],
'ip6s': [ip6_dict(ip) for ip in network_IPs]}
ip6_dict should probably be called only if use_ipv6 is True
