For Two-Node with Fencing (TNF), only the following platforms are supported:
- baremetal
- external
- none

The `vsphere` and `nutanix` platforms are not supported for two-node clusters with fencing.


For platform `none`:

* The `none` option requires the provision of DNS name resolution and load balancing infrastructure in your cluster. See _Requirements for a cluster using the platform "none" option_ in the "Additional resources" section for more information.

* Review the information in the link:https://access.redhat.com/articles/4207611[guidelines for deploying {product-title} on non-tested platforms] before you attempt to install an {product-title} cluster in virtualized or cloud environments.
