Switch to centos-release-openstack-queens for ovs
Drop the dependency on RDO infra in favor of latest OVS releases in
centos-7. This means we'll be bumping to 2.9.0.

This still isn't the best, as we are pinning to a specific release of
openstack. However, until there is the OVS SIG in centos, this is the
best we can do.

Configures a VXLAN virtual network overlay through an openvswitch network bridge between a 'switch' node and 'peer' nodes.

This allows members of the bridge to communicate with each other through the virtual network.

By default, this role will:

  • Install and start openvswitch
  • Set up a br-infra bridge on all nodes
  • Set up the connectivity between the switch and the peer with a virtual port
  • Set up an ip address on the bridge interface:
172.24.4.1/23 # switch node
172.41.4.2/23 # first peer
172.41.4.3/23 # second peer
...

Role requirements

This role requires and expects two groups to be set up in the Ansible host inventory in order to work:

  • switch (the node acting as the switch)
  • peers (nodes connected to the virtual switch ports)
