Alfredo Moralejo 64fd772a32 Change RDO train repository for Centos 8 stream
After removing Centos 8 repositories [1], the repository has been
set to buildlogs server, which provides testing packages.
This commit is switching back repository to mirror.centos.org once we
have openvswitch in centos network and AFS mirrors.

README.rst

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)
