Vagrant using Qemu-KVM provider

Introduction

In this tutorial, How to install and run Vagrant using Qemu-KVM. You use Vagrant for DevOps professionals, coder sysadmin. I will be installing and be running Vagrant on My Laptop is Fedora 32. Now, let’s go Vagrant using Qemu-KVM provider.

Installing and running Vagrant using Qemu-KVM

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
