Hello, I have a requirement to create virtual machines with four interfaces. So, I created four networks and assigned each network a subnet using "neutron". So far so good. When I lauch the virtual machine, I see only the first interface is up and getting its IP address using DHCP. Why are the other three interfaces not coming up and getting their IP addresses?

**Test Environment**  
openstack version - havana 
OS used on host machines - RHEL-6.4  

**Two node openstack setup** 
Controller - services: neutron dhcp agent, neutron ovs agent, neutron server 
Compute1 - services: nova compute, neutron ovs agent

I used below environment for creating networks and subnets.

export OS_USERNAME=admin
export OS_PASSWORD=changeit
export OS_TENANT_NAME=admin
export OS_AUTH_URL=http://controller:35357/v2.0

The way I created the networks is something below.

neutron net-create basenet_110 --provider:network_type vlan  --provider:physical_network basenet --provider:segmentation_id 110
neutron net-create basenet_111 --provider:network_type vlan  --provider:physical_network basenet --provider:segmentation_id 111

Please let me know, if you need more information. Thanks.
