Description Pierre Prinetti 2020-09-25 15:04:00 UTC

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.

Comment 1 Pierre Prinetti 2020-09-25 15:04:58 UTC

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

Comment 4 David Sanz 2020-10-02 10:12:59 UTC

Verified doc
