Vagrant
 
   from https://www.vagrantup.com

--

Install libvirt and qemu:
   dnf -y install qemu libvirt libvirt-devel ruby-devel gcc
  source: https://github.com/vagrant-libvirt/vagrant-libvirt#possible-problems-with-plugin-installation-on-linux

Install vagrant:
    https://www.vagrantup.com/docs/installation/index.html
    https://www.vagrantup.com/downloads.html


Install vagrant plugin for libvirt:

vagrant plugin install vagrant-libvirt

--
To list all the plugins:

  vagrant plugin list

To repair the plugins if you run into issues:

 vagrant plugin repair

To update the plugin:

  vagrant plugin update 

--

First init the Vagrantfile
vagrant init fedora/29-cloud-base

// Note: You can check whether the corresponding image present here
// https://app.vagrantup.com/fedora

--

// without any specific OS:
vagrant init

You need to update Vagrant file with specific OS before proceeding.

--
To create and configure and to bring up the VM
vagrant up --provider=libvirt

--

You can find your downloaded box here:
ls ~/.vagrant.d/boxes/

--

vagrant status
// only for current directory
--

vagrant global-status
// global for this user
--

vagrant halt  <id>

id is received in global-status command above
--

To start again:
vagrant provision

or  you can run the same command as:
vagrant up --provision 

You can also avoid running it by
vagrant up --no-provision 

--
// To login
vagrant ssh

--

// To destroy specific box

vagrant destroy

// Note, the above will not remove the box from the system (from backend). 

// To remove it you can use

vagrant box remove  

--

// remembers the state saving the state of VM
vagrant suspend

// To resume back
vagrant resume

--

// To stop:
vagrant halt
--

// List all the boxes in your system:
vagrant box list

--

// To share files between host and VM

// option in Vagrantfile
  config.vm.synced_folder "../data", "/vagrant_data"

Here ../data => directory in Host
/vagrant_data => directory in VM

Ensure you have working NFS server in host.
Also, udp=y in /etc/nfs.conf in the host machine.

--

vagrant reload ->  vagrant halt + vagrant up

// along with provision
vagrant reload --provision

--

// provider specific changes in Vagrantfile
   vb.memory = "value"
   vb.cpus = "value"

--

// to package a new vagrant box
vagrant package

--
