 ## Virtual Machine (VM) based RHOCP cluster 
 
 Multi-node bare metal RHOCP cluster provisioning is the primary cluster use case supported by the project. Virtual Machine technology-based infrastructures support will be included in a future release. For feature requests and related discussions, please submit a project [issue](https://github.com/intel/intel-technology-enabling-for-openshift/issues). For RHOCP infrastructure support, please contact Red Hat.
