vSphere Clusters Are Not Shown In Platform9 Authorization Wizard
The most common reason for this is if VMware DRS is not enabled for the cluster.
Platform9 (OpenStack) requires that VMware DRS is enabled in order to work with a cluster.
After you enable DRS on the cluster, it will take upto 30 minutes for Platform9 to discover that cluster and report it as part of the gateway authorization wizard.
To trigger this immediately, please follow this Tutorial to re-authorize the gateway.
