Hello All,
I have been trying to duplicate this guide here mostly.
https://developer.rackspace.com/blog/neutron-networking-vlan-provider-networks/
The provider network part is useful to me but the gre tunnels and and dhcp are
not needed for us. We want to assign the addresses via a central build server
rather than having openstack manage it on a site to site basis.
The VLANs are trunked to the port of the management server and the
compute/network node. The VLAN stuff is verified working through manual
testing. When I tcpdump eth0 I also see lldp announcements showing the right
information in regards to vlans and so on.
I run a standalone management server. I am running the network and compute node
on the second server and I modified necessary settings using the installation
guide for icehouse on docs.openstack.org. I then used some of the settings
above to create the OVS settings.
I have one network card per chassis, a 10Gb Intel adapter.
eth0 has no addressing
I have a bridge called br-eth0 with the addressing from the management network
assigned to it.
Here are my settings from /etc/neutron/plugin.ini (ml2_conf.ini). These are
consistent across the management and compute/network host. Everything seems to
be communicating with its databases fine.
I have tried commenting out the [ml2] stuff and using just the [ovs] stuff to
no success. 106 and 400 are the vlans I configure here and the network is
labelled openstack. We have a third management network but traffic on that is
all untagged.
Here are the parameters set below currently.
[ml2]
type_drivers = vlan
tenant_network_types = vlan
mechanism_drivers = openvswitch
[ml2_type_vlan]
network_vlan_ranges = openstack:106:106,openstack:400:400
[ovs]
enable_tunneling = False
integration_bridge = br-int
bridge_mappings = openstack:br-eth0
network_vlan_ranges = openstack:106:106,openstack:400:400
Neutron net-list shows the networks created when I run the provider commands
linked in the article above. I added a gateway to the address space though as
the cirrus image wouldn't launch without a gateway defined to the network range.

When I check the web interface the correct segmentation IDs are assigned to
each network
For example in VRF
Provider Network
Network Type: vlan
Physical Network: openstack
Segmentation ID: 106

When I launch the vm build without networking the build succeeds and creates
its own network port in each subnet even when not specifying the -nic and
-net-id stuff with nova boot command . Neither respond to ping and when you
login to the vm via you get nowhere even if you assign address as the tagging
applied is random. The web interface shows the port up and active in the subnet
and the device owner is compute:None .

Is there some step I am missing in the plugin.ini (ml2_conf.ini) file that is
stopping me from creating vms with network? It can't be nova as the vm launches
when no network is specified? I have had a second admin check my configuration
files and it followed the guide to a letter aside from the modified network
settings we need to suit out setup which is why I am thinking this is where I
have gone wrong.
Thanks,
Alex
