ovn-vagrant: Virtual OVN Cluster using Vagrant

Install vagrant and libvirt provider:

sudo yum install -y vagrant
sudo yum install -y vagrant-libvirt

Avoid having to enter credentials every time vagrant does something with libvirt:

sudo gpasswd -a ${USER} libvirt
newgrp libvirt

Checkout this repository.

git clone https://github.com/hlrichardson/ovn-vagrant
cd ovn-vagrant

Create CentOS VMs (OVN central and two OVN compute nodes)

vagrant up --provider libvirt

Look around in central node:

vagrant ssh central
sudo ovn-sbctl show
exit

Look around in compute1 node:

vagrant ssh compute1
sudo ovs-vsctl show
exit

Look around in compute2 node:

vagrant ssh compute2
sudo ovs-vsctl show
exit

When done, clean up:

vagrant destroy
