Hi all!

I'm deploying an HA overcloud with 3 controller nodes and 3 compute nodes.

I'm able to successfully deploy the overcloud in GRE-tunnel mode by issuing the following command:

openstack overcloud deploy --control-scale 3 --compute-scale 3 --libvirt-type kvm --ntp-server pool.ntp.org --templates ~/the-cloud/ -e ~/the-cloud/environments/puppet-pacemaker.yaml -e ~/the-cloud/environments/network-isolation.yaml -e ~/the-cloud/environments/net-single-nic-with-vlans.yaml -e ~/the-cloud/environments/network-environment.yaml --control-flavor controller --compute-flavor compute


Now I want to use VLAN in tenant networks, disabling the GRE-tunnels.

I ran the following command to deploy the overcloud in VLAN mode:

 openstack overcloud deploy --control-scale 3 --compute-scale 3 --libvirt-type kvm --ntp-server pool.ntp.org --templates ~/the-cloud/ -e ~/the-cloud/environments/puppet-pacemaker.yaml -e ~/the-cloud/environments/network-isolation.yaml -e ~/the-cloud/environments/net-single-nic-with-vlans.yaml -e ~/the-cloud/environments/network-environment.yaml --control-flavor controller --compute-flavor compute --neutron-network-type vlan --neutron-bridge-mappings datacentre:br-ex --neutron-network-vlan-ranges datacentre:1000:10009

However I always get the following error:
ERROR: openstack Neutron tunnel types must be specified when Neutron network type is specified

I think this problem might be related to this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1244893

Yes, the error relates to that bug: you should pass both --neutron-network-type vlan and --neutron-tunnel-types vlan to pass.

In addition to this you should also make sure that the network templates match your physical environment, provide valid vlan range(10009 is not a valid vlan tag), switch configuration is in place.
 

Do you have any suggestions on how to solve this problem?

Thank you very much!
Regards,
