+## Setup for Vagrant using libvirt provider
+
+* Create vagrant_variables.yml
+
+```
+$ cp vagrant_variables.yml.sample vagrant_variables.yml
+```
+
+* Edit `vagrant_variables.yml` and setup the following variables:
+
+```yml
+memory: 1024
+disks: "[ '/dev/vdb', '/dev/vdc' ]"
+vagrant_box: centos/7
+```
+
+* Create site.yml

+```
+$ sudo vagrant up --no-provision --provider=libvirt
+$ sudo vagrant provision
