It seems Compute node is not able to reach the Instance via its tap interface. Thanks

2016-11-23 01:24:19 -0600 commented question Openstack Neutron VLan Networking Issue

Security Groups are fine, instances do have an IP address assigned with an IP from the external network. the packet reaches the Compute Node's NIC but not on the Instance's Tap interface. Thanks

i followed the article for vlan tagging on the server side. (

So thats why br-ex.14 was created. is it required if i have to connect my VMs on external network of segmentation id 14.

2016-11-23 01:19:01 -0600 commented question Openstack Neutron VLan Networking Issue

The installation was done via RDO packstack and OVS bridge br-ex was created with a NIC(eth1) on the compute node as a port to the OVS Bridge.

Any step that i am missing over here, or any direction you would like to point me in.

Have already gone through ( but didnt work out.

Please suggest, would really appreciate.

Thanks in advance.

Hi Bernd, Greetings!! Really appreciate your response.

The Physical network name I decided is "vlan" and have checked the correct bridge mapping in

/etc/neutron/plugins/ml2/openvswitch_agent.ini bridge_mappings =vlan:br-ex

I have also updated the command as above, but still not successful

2016-11-18 09:18:44 -0600 asked a question Openstack Neutron VLan Networking Issue

I am facing Neutron Vlan networking issue in Openstack Mitaka, that is am not able to make my instance reachable from my physical vlan network after attaching them directly to the vlan network i created in Openstack with the segmentation id of my physical vlan network.

2 Node setup :- 1 compute node + 1 compute/controller/network node Separate NICs for Management(eth0) & Overlay/Instance Traffic(eth1, br-ex OVS bridge mapped)

Here are the steps i followed:-

a) Physical Switch Trunk mode configuration done on switch port to which NIC on Compute/Network node is connected for Instance/Overlay traffic. It allows vlan 14 to flow.

b) ifcfg-br-ex.14 created on both nodes to allow vlan 14 tagged traffic

c) ml2_conf.ini on Network/Controller node

type_drivers = vlan,gre
tenant_network_types = vlan,gre
mechanism_drivers =openvswitch
path_mtu = 0

network_vlan_ranges =vlan:14:14


firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver
enable_security_group = True

d) openvswitch_agent.ini on both nodes


integration_bridge = br-int
tunnel_bridge = br-tun
bridge_mappings =vlan:br-ex


firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver

e) Create network

neutron net-create vlan_X --shared --provider:network_type vlan --provider:segmentation_id 14 --provider:physical_network vlan ­­router:external

f) Create Subnet

neutron subnet-create --name subnet_X --gateway 172.29.X.1 --disable-dhcp --allocation-pool start=172.29.X.250,end=172.29.X.253 vlan_X 172.29.X.0/24 --dns-nameserver 172.29.X.2 --host_routes type=dict list=true destination=,nexthop=172.29.X.1

Note:Some IP details hidden

h) After which i launch an instance on vlan_X, it is not reachable from my external vlan network.

Any step i am missing? Please suggest, it will really help me.

Please let know for more info.

What type of Network are you creating? is it vlan? if it is vlan then you need to ensure that vlan segmentation id is recognized with a subnet on the physical switch to which both the Controller and the compute is connected, so that the vlan traffic is allowed to flow on the switch

It seems that you may be using CEPH as a backend for Glance...There are some basic requirements for this, make sure that you have set proper permissions in the CEPH keyring. please validate your settings using the below articles:- ( (

2016-09-26 00:59:49 -0600 answered a question Need a Help..Please help me on below installation error

You will have to troubleshoot rabbitmq-server service individually before running the packstack again..Check if you have set CONFIG_AMQP_ENABLE_SSL=n, otherwise sometimes it is found after enabling AMQP SSL it is required to modify the default port for SSL in /etc/rabbitmq/rabbitmq.config, as it also tries to listen on 5672.

You can also tail /var/log/rabbitmq/<>.log while starting the rabbitmq-server service for any more informtion.
