Vagrant use KVM provider

Introduction

In this tutorial, I’ll guide you on installing and running Vagrant use KVM provider. Whether you’re a DevOps professional, coder, or sysadmin, Vagrant proves invaluable. I’ll walk you through the installation and setup process on my Fedora 32 laptop. Together, we’ll explore the seamless integration of Vagrant with the Qemu-KVM provider, opening up new possibilities for efficient development environments. Let’s dive into the steps to harness the power of Vagrant and enhance your workflow on Fedora 32.

Installing and running Vagrant use KVM provider

Check the machine supports virtualization

[HuuPV@DevopsRoles ~]$ sudo lscpu | grep Virtualization
Virtualization:                  VT-x

Install qemu-kvm

[HuuPV@DevopsRoles ~]$ sudo dnf install qemu-kvm libvirt libguestfs-tools virt-install rsync
[HuuPV@DevopsRoles ~]$ sudo systemctl enable --now libvirtd

Install Vagrant and vagrant libvirtd plugin

[HuuPV@DevopsRoles ~]$ sudo dnf install vagrant
[HuuPV@DevopsRoles ~]$ sudo vagrant plugin install vagrant-libvirt

Using the vagrant box command to Add a box

Link download box here

[HuuPV@DevopsRoles vagrant-test]$ vagrant box add centos/7 --provider=libvirt

==> box: Loading metadata for box 'centos/7'
    box: URL: https://vagrantcloud.com/centos/7
==> box: Adding box 'centos/7' (v2004.01) for provider: libvirt
    box: Downloading: https://vagrantcloud.com/centos/boxes/7/versions/2004.01/providers/libvirt.box
Download redirected to host: cloud.centos.org
    box: Calculating and comparing box checksum...
==> box: Successfully added box 'centos/7' (v2004.01) for 'libvirt'!

Test: Create a minimal Vagrantfile

$ mkdir vagrant-test
$ cd vagrant-test
$ vi Vagrantfile
# An example which also sets the amount memory and number of CPUs in Vagrantfile file

Vagrant.configure("2") do |config|
  config.vm.box = "centos/7"
  config.vm.provider :libvirt do |libvirt|
    libvirt.cpus = 1
    libvirt.memory = 1024
  end
end

Start the box

vagrant up

The output is an example below:

[HuuPV@DevopsRoles vagrant-test]$ vagrant up

Connect to your new machine

vagrant ssh

The output as the example below

[HuuPV@DevopsRoles vagrant-test]$ vagrant ssh
[vagrant@localhost ~]$ hostname
localhost.localdomain
[vagrant@localhost ~]$ pwd
/home/vagrant
