# Vagrant oVirt v4 Provider

This is a [Vagrant](http://www.vagrantup.com) 1.1+ plugin that adds an
[oVirt v4](http://ovirt.org) and
allowing Vagrant to control and provision machines in oVirt.

## Installation

```
$ vagrant plugin install vagrant-ovirt4
$ vagrant up --provider=ovirt4
```

## Usage

### Prerequisites

#### Configuration

1. [ovirt-guest-agent](https://github.com/oVirt/ovirt-guest-agent)
1. [cloud-init](https://cloudinit.readthedocs.io/en/latest/)
1. User 'vagrant'
  1. password 'vagrant'
  1. Public key [from here](https://raw.githubusercontent.com/mitchellh/vagrant/master/keys/vagrant.pub)
  1. add to group with sudo no password
1. set `!requiretty` in sudoers
1. firewall off and ssh enabled

#### Example creation steps

1. Create a base template
  1. Centos Example
    1. Spin up a virtual machine using the Centos 7 Generic Cloud Image from the ovirt Glance provider
    1. Once it is up and running, run [the example script](tools/prepare_redhat_for_box.sh) from inside the VM
    1. Power down the virtual machine
    1. Remove all Network Interfaces from the VM (so that the template does not have it)
    1. Right click the virtual machine and click 'Make Template'

### Supported Commands (tested)

1. `vagrant up`
1. `vagrant destroy`
1. `vagrant ssh [-c '#command']`
1. `vagrant ssh-config`
1. `vagrant halt`
1. `vagrant reload`
1. `vagrant status`
1. `vagrant suspend`
1. `vagrant resume`
1. `vagrant snapshot list`
1. `vagrant snapshot delete [id]`
1. `vagrant snapshot save [description]`

### Configuration example

```
Vagrant.configure("2") do |config|
