 Install tests are a collection of tests defined under the [tests/install](./tests/install). These tests are used to validate the installation and operation of K3s on a variety of operating systems. The test themselves are Vagrantfiles describing single-node installations that are easily spun up with Vagrant for the `libvirt` and `virtualbox` providers:
 
 - [Install Script](install) :arrow_right: scheduled nightly and on an install script change
-  - [CentOS 7](install/centos-7) (stand-in for RHEL 7)
+  - [CentOS 9 Stream](install/centos-stream)
   - [Rocky Linux 8](install/rocky-8) (stand-in for RHEL 8)
   - [Rocky Linux 9](install/rocky-9) (stand-in for RHEL 9)
-  - [Fedora 37](install/fedora)
-  - [Leap 15.5](install/opensuse-leap) (stand-in for SLES)
-  - [Ubuntu 22.04](install/ubuntu-2204)
