You can use vRealize Automation custom properties to add values or override existing or default values for configuring settings for network, platform, guest agent, and many other deployment parameters.
Some properties are determined by standard settings that you must specify for all machines. For example, memory and disk size values are required for all blueprints. You can specify additional properties individually or in property groups in blueprints and in reservations. When you add a property to a blueprint or a property group, you can mark it as a required property. When a property is specified as required, the user must provide a value for that property when they request a machine, such as in the following examples.
Require information about multiple disks sharing the machine’s allocated storage.
Require information about users or groups to be added to a local group on the machine.
Require the host name of the machine.
The Windows guest agent records property values on the provisioned machine in the %SystemDrive%\VRMGuestAgent\site\workitem.xml file.
The Linux guest agent records property values on the provisioned machine in the /usr/share/gugent/site/workitem.xml file.
