libvirt
Explicit Need Only
VMs are ONLY used to test specific cases which cannot be tested in containers (kernel, firmware, proc, systemd, networking, etc.) these should never be default test cases.
Always use root
Vagrant images require becoming root for executing tasks as the default vagrant user is unprivileged.
