Installing Vagrant + libvrt plugin in Centos 8

#vagrant #centos #tutorial #libvirt

Has been a while since I have used vagrant and when I did, I just used the default virtualbox to test oracle-base RAC installations

Now that I'm thinking about how to create a Oracle RAC cluster using Ansible (there are few places you can find how to do it, but the fun part is to figure it out by yourself, right?) I thought is good idea to use Vagrant to make few things easier.

The original Idea was to create a post to get Vagrant boxes deployed using Ansible, but just getting Vagrant working with the libvrt plugin in my Centos 8 server was so painful, that I decided to create this post where I only install Vagrant + libvrt plugin so I can follow the same steps next time I need to reinstall the system.

Let's start installing Vagrant. I just followed this Process which also mentions how to get libvrt plugin

The solution is similar to this github post
More info of both errors can be found here

The main issue is that both describe the issue for fedora and I needed to manually locate the libssh rpm source file libssh-0.9.4-2.el8.src.rpm
