Vagrant enables users to create and configure lightweight, reproducible, and portable development environments.
installing and using vagrant on fedora 26
#sudo dnf install vagrant -y Last metadata expiration check: 2:10:16 ago on Sunday 25 March 2018 06:58:56 PM IST. Package vagrant-1.9.1-3.fc26.noarch is already installed, skipping. Dependencies resolved. Nothing to do. Complete!
initialize vagarant file with
$ vagrant init centos/7 A `Vagrantfile` has been placed in this directory. You are now ready to `vagrant up` your first virtual environment! Please read the comments in the Vagrantfile as well as documentation on `vagrantup.com` for more information on using Vagrant.
#installing vagrant plugins
$vagrant plugin install vagrant-rekey-ssh ; vagrant plugin install vagrant-mutate ; vagrant plugin install vagrant-libvirt
$lets edit the Vagarntfile file and add some configuration options.

Checking vagrant status
$ vagrant status Current machine states: one running (libvirt) two running (libvirt) This environment represents multiple VMs. The VMs are all listed above with their current state. For more information about a specific VM, run `vagrant status NAME`.
To access running vms we can use vagrant ssh command.
$vagrant ssh one [vagrant@one ~]$ hostname one.vagrant.box [vagrant@one ~]$ exit logout Connection to 192.168.121.220 closed. $ vagrant ssh two [vagrant@two ~]$ hostname two.vagrant.box [vagrant@two ~]$ exit logout Connection to 192.168.121.32 closed.
