Prerequisites to using Red Hat OpenShift Virtualization on Red Hat OpenShift Service on AWS

• How to prepare your environment for Red Hat OpenShift Service on AWS (ROSA) and OpenShift Virtualization

• Red Hat account
• AWS account
• ROSA cluster running with bare metal nodes

Because OpenShift Virtualization requires bare metal nodes, it is important to first create these within your ROSA cluster. The following steps will walk you through the process of adding “m5.metal node” to your machine pool. You may also refer to these instructions if needed.

1. Open a new tab or window and sign in to your Hybrid Cloud Console. 
2. Click Clusters in the left hand menu and select your ROSA cluster.
3. Click Machine Pools in the upper menu.
4. Click the Add Machine Pool button. 
5. Name your machine pool and select the m5.metal node (96 vCPU, 384 GiB RAM) option under the Compute node instance type menu. 
6. Click the Enable autoscaling checkbox to select it and set Minimum node count to 2 and Maximum node count to 3.
   1. Note: The minimum must be 2 for supported workloads. The maximum may be any number up to the platform max, but the autoscaler requires a number greater than the minimum. Maximum of 3 in the instructions above is for demo/example purposes, and your platform max/needs may vary.  
7. Click Add machine pool in the lower left of the modal. 
8. After the pool is created, click the Edit cluster autoscaling button and click the Autoscale cluster button in the upper left of the modal that appears.
9. Click Close in the lower left to exit the modal.

Once you’ve met these prerequisites, you are now ready to configure OpenShift Virtualization.
