Vagrant is a tool for building and managing virtual machines locally with just a few commands and a single file. It is a good way to get started with infrastructure-as-code on your local machine. Vagrant is also shipped with Fedora to make it easier to install and use as it uses libvirt to manage the virtual machines running on Linux with kernel virtualization to provide virtual hardware. This works well until you also want to install Terraform from the HashiCorp repository and later you upgrade Vagrant to a newer version with a regular package update.
In the example above Vagrant fails to find libvirt to connect to KVM and manage the virtual machine. Multiple providers are available for Vagrant to use, but the one that is used is not the one that is installed on the machine or can be used. This is a known issue with Vagrant on Linux and does not use the system Ruby environment with the lirbary for libvirt. Downgrading to the version of Vagrant that is shipped with Fedora will fix this issue.

HashiCorp Vagrant normally selects the right hypervisor, but the version shipped with Fedora 30 prefers to run within the QEMU user session of the hypervisor. A .Vagrantfile it would match the default behavior which doesn’t require any system privileges is shown below.
In some cases a virtual machine needs to run on QEMU system level and that can be done by changing the domain.uri from “qemu:///session” to “qemu:///system”. Vagrant now creates the virtual machine at the system level of the hypervisor and isn’t depending on any user environment to run.
