Subject: Re: [Fuel-dev] VMs are not getting IP address
Gandhi,
Looking over the support bundle, I see that node-17's /etc/neutron/plugin.ini and /etc/neutron/plugins/ml2/ml2_conf.ini are not the same file, they should be linked. You should also ensure that the /etc/init/neutron-server and /etc/init/neutron-plugins-openvswitch-agent are pointing to /etc/neutron/plugin.ini
[Gandhi] We tried linking the files in node-17 and restarted the services. But still it didn’t work (VM created successfully but IP address is not assigned).
The ml2_conf.ini has
[ovs]
tenant_network_type = vlan
As far as I'm aware this is not a value for ovs.
[Gandhi] vlan is the value we used to give for Brocade plugin testing. We have provided the same value in other setups (Non-Mirantis setups) and it is working fine.
You described above that you are attempting to pass the ostf test which launches and instance and checks access via floating IP, this test will require a L3 agent, and router in neutron.conf service_plugins.
The repo for the ml2 brocade code https://github.com/openstack/neutron/tree/master/neutron/plugins/ml2/drivers/brocade shows that the config for the brocade driver should be in the seperate plugins/ml2/ml2_brocade_conf.ini although the code https://github.com/openstack/neutron/blob/master/neutron/plugins/ml2/drivers/brocade/mechanism_brocade.py#L47 implies that the heading [ml2_brocade] usable.
There are also many Traceback maessages in neutron-server.log http://paste.openstack.org/show/86975/ It seems that there are errors in the xml RPC calls being processed by the switch.
[Gandhi] At /etc/neutron/plugins/ml2/ml2_conf_brocade.ini, below lines are available.
[ml2_brocade]
username = admin
password = password
address = 10.25.225.133
ostype = NOS
physical_networks = physnet1
Also in /etc/neutron/plugins/ml2/ml2_conf.ini, we have below lines of code –
[ml2_brocade]
username = admin
password = password
address = 10.25.225.133
ostype = NOS
physical_networks = physnet1
Note: These two .ini files have same configurations in Mirantis environment as we have provided for other setups (Non Mirantis setups).

Subject: RE: [Fuel-dev] VMs are not getting IP address
Hi Miroslav, Andrew,
We have configured below core_plugins at /etc/neutron/neutron.conf. Furthermore, we are not using service_plugin, since it is not required for our current brocade vcs plugin testing.
core_plugin = neutron.plugins.ml2.plugin.Ml2Plugin
Among the quantum settings mentioned by Andrew, only below configurations are applicable for our Brocade plugin testing -
[ml2]
tenant_network_types = vlan
type_drivers = vlan
mechanism_drivers = openvswitch,brocade
Diagnostic snapshot is available at https://www.dropbox.com/s/o8kt0istezimlim/fuel-snapshot-2014-07-16_05-08-37.tgz

Subject: Re: [Fuel-dev] VMs are not getting IP address
Gandhi,
by hand,
You will need to ensure that you configure in /etc/neutron/neutron.conf core_plugin, service_plugins, you will also need to check your init scripts for neutron-openvswitch-agent, and neutron-server to ensure that they are reading the ml2.ini. You will also need to install the ml2 (neutron-plugin-ml2, openstack-neutron-ml2[if centos]) and brocade packages.
You can follow an example ml2 configuration at http://www.revolutionlabs.net/2013/11/part-2-how-to-install-openstack-havana_15.html
If you are testing against current master, we just landed code to configure ml2 last week https://review.openstack.org/#/c/106731/1/deployment/puppet/neutron/lib/puppet/parser/functions/sanitize_neutron_config.rb.
You can now add ml2 data to quantum_settings in astute.yaml
quantum_settings:
server:
core_plugin: openvswitch
service_plugins:
'neutron.services.l3_router.l3_router_plugin.L3RouterPlugin,neutron.ser
vices.firewall.fwaas_plugin.FirewallPlugin,neutron.services.metering.metering_plugin.MeteringPlugin'
L2:
mechanism_drivers:
type_drivers: "local,flat,l2[:segmentation_type]"
tenant_network_types: "local,flat,l2[:segmentation_type]"
flat_networks: '*'
tunnel_types: l2[:segmentation_type]
tunnel_id_ranges: l2[:tunnel_id_ranges]
vxlan_group: "None"
vni_ranges: l2[:tunnel_id_ranges]
Note: tunnel_types, tunnel_id_ranges, vxlan_group, vni_ranges are only set if L2[enable_tunneling] is true.
Note: there are some l2[item] references, these are references to values already in the quantum_settings.
Note: these are only showing new items related to ml2 config. The values shown are the defaults if no other value is present.
