The documentation about bare metal workers describes how to "Deploy a cluster with VM workers only and add BM workers after"[1]. This use case was designed for supporting OpenStack configurations where: - The bare metal machines can only exist on a specific provider network - It is not allowed to create VMs on the specific provider network where BMs exist. The documentation details how to create a BM MachineSet on a separate subnet, on the provider network. However, OpenShift on Openstack v4.6 does not support additional MachineSets in separate subnets.

Setting a low severity because the expected resolution entails a change in the documentation only.
