Hi ,

When I am configuring ML2 plugin with vlan based network ,  nova boot is failing with following error ,where as if I change the driver from ML2 to OVS  , things are working fine .
Please suggest.


Here is the ml2 configuration:

[ml2]
type_drivers = vlan
tenant_network_types = vlan
mechanism drivers = openvswitch
[ml2_type_vlan]
network_vlan_ranges = physnet1:1:4094
[ovs]
tenant_network_type = vlan
network_vlan_ranges = physnet1:1:4094
bridge_mappings = physnet1:br-eth1
[securitygroup]
firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver
enable_security_group = True

/etc/neutron/neutron.conf:
core_plugin = ml2
service_plugins = router
allow_overlapping_ips = True
