+# Local development
+
+## Create a RHEL 9 Virtual Machine
+
+Pre-requisites :
+- Fedora 39 [with Libvirt installed](https://docs.fedoraproject.org/en-US/quick-docs/virtualization-getting-started/)
+
+Download [RHEL 9.3](https://access.redhat.com/downloads/content/rhel) and save `rhel-9.3-x86_64-kvm.qcow2` in `/var/lib/libvirt/images/base-images`.
+
+Create a file named `user-data.yaml` with the follwing content.
+
+```yaml

+
+Create the RHEL9 VM.
+
+```sh
