Virtual Appliance Installation
To deploy the vRealize Automation appliance, you must have the appropriate privileges on the deployment platform (for example, vSphere administrator credentials).
During the deployment process, you specify the password for the virtual appliance administrator account. This account provides access to the vRealize Automation appliance management console from which you configure and administer the virtual appliances.
