When installing OpenShift on vSphere using the Assisted Installer, the installation flow does not create MachineSets or Machines automatically.
This is expected behavior, but currently not documented anywhere in our official docs, and customers may run into issues when trying to scale their cluster or add worker nodes later.

We created an internal step-by-step guide that documents:

• The missing conceptual note that Assisted Installer does not create MachineSets for vSphere installs.
• Required post-install vSphere configuration (cloud provider integration must be completed before Machine API works).
• How to create a clean RHCOS OVA-based template properly.
• How to build a vSphere MachineSet YAML (with placeholder explanation).
• How to validate the MachineSet, monitor Machine lifecycle, and confirm node join.
• Scaling (manual & autoscaling) instructions.
• Trouble-shooting for typical failure cases.

This content would significantly help customers and reduce support load.

The guide PR is not merged yet and can be found here https://github.com/openshift/assisted-service/pull/8441.{}

Request:
Add a new documentation section to the Assisted Installer / vSphere docs:

Proposed title:
“Adding Worker Nodes Using MachineSets on vSphere (Assisted Installer)”

Location suggestion:

Installing on vSphere (near or after “Post-installation configuration” section)
