+
+## Vagrant with libvirt as default provider
+
+To use use Vagrant with libvirt you need to install the `vagrant-libvirt` plugin. The Vagrant way would be:
+
+```
+vagrant plugin install vagrant-libvirt
+```
+
+In some linux distributions you find this plugin in their repositories.
+
+Fedora (`vagrant-libvirt` is a dependency of the `vagrant` package.):
+
+```
+sudo dnf install vagrant-libvirt
+```
+
+ArchLinux (`vagrant-libvirt` is found in [AUR](https://aur.archlinux.org/packages/vagrant-libvirt)):
+
+```
+yay -S vagrant-libvirt
+```
+
+After this you need to set libvirt as default provider for Vagrant:
+
+```
+# Vagrant config
+export VAGRANT_DEFAULT_PROVIDER=libvirt
+```
+
+## vagrant mutate
+
+If you need any image that is not present for your provider, e.g. libvirt, you can use `vagrant mutate`. To install it the vagrant way use:
+
+```
+vagrant plugin install vagrant-mutate
+```
+
+After installing you can convert one provider into another one like this:
+
+```
+vagrant mutate centos/7 virtualbox
+```
+
+Then you'll see two boxes ready:
+
+```
+$ vagrant box list
+centos/7 (libvirt, 2004.01)
+centos/7 (virtualbox, 2004.01)
+```
