You will need to set the `multinode_flavor`, `multinode_keypair`, `prefix`,
`ssh_public_key`, and `ssh_user` (such as using the user `ubuntu`
if you're using ubuntu or `cloud-user` on Rocky Linux 9, etc).
You will need to set the `multinode_keypair`, `prefix`, and `ssh_public_key`.
By default, Rocky Linux 9 will be used but Ubuntu Jammy is also supported by
changing `multinode_image` to `Ubuntu-22.04-lvm` and `ssh_user` to `ubuntu`.
Other LVM images should also work but are untested.

The `multinode_flavor` will change the flavor used for controller and compute
nodes. Both virtual machines and baremetal are supported, but the
`controller_disk_size` and `compute_disk_size` must be set to 0 when using
baremetal host. This will stop a block device being allocated.
nodes. Both virtual machines and baremetal are supported, but the `*_disk_size`
variables must be set to 0 when using baremetal host. This will stop a block
device being allocated. When any baremetal hosts are deployed, the
`multinode_vm_network` and `multinode_vm_subnet` should also be changed to
`stackhpc-ipv4-vlan-v2` and `stackhpc-ipv4-vlan-subnet-v2` respectively.

If `deploy_wazuh` is set to true, an infrastructure VM will be created that
hosts the Wazuh manager. The Wazuh deployment playbooks will also be triggered
