In the last recipe, we preconfigured virtual machines using Vagrant; they are to be used with VSM. In this recipe, we will learn about the preflight configuration that is needed on these VMs so that it can be used with VSM.
Please note that by using Vagrant, we have done most of this preflight configuration using the shell script file, Ceph-Cookbook-Second-Edition/vsm/post-deploy.sh, present in the GitHub repository that we cloned in the last recipe. You might not want to repeat these first four steps as Vagrant already performed them. We are explaining these steps here so that you can learn what Vagrant did in the background.
