Initialize Vagrantfile

$ vagrant init centos/7
A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment!

Installing vagrant plugins

$ vagrant plugin install vagrant-rekey-ssh ; vagrant plugin install vagrant-mutate ; vagrant plugin install vagrant-libvirt

Vagrantfile configuration

# vi: set ft=ruby :
 
Vagrant.configure("2") do |config|
 
config.vm.define :one do |one|
one.vm.box = "centos/7"

Spinning up VMs

$ vagrant up
Bringing machine 'one' up with 'libvirt' provider...
Bringing machine 'two' up with 'libvirt' provider...
==> one: Creating image (snapshot of base box volume).
==> two: Creating image (snapshot of base box volume).
==> one: Creating domain with the following settings...
==> one:   -- Name:              cipher_one
==> one:   -- Domain type:       kvm
==> one:   -- Memory:            420M
==> two:   -- Name:              cipher_two
==> two:   -- Domain type:       kvm

Checking vagrant status

$ vagrant status
Current machine states:

one                       running (libvirt)
two                       running (libvirt)

Accessing VMs

$ vagrant ssh one
[vagrant@one ~]$ hostname
one.vagrant.box

$ vagrant ssh two
[vagrant@two ~]$ hostname
two.vagrant.box
