Custom Property Types
You can use vRealize Automation external and updated property types for cloned machines. You cannot use
Internal and read-only property types for cloned machines.
The following vRealize Automation custom property types are available.
n
Internal
The specied value is maintained in the database only. For example, the email address of the manager
who approved a machine request is recorded in the VirtualMachine.Admin.Approver property but the
property has no eect on the machine.
n
Read-only
The specied value is implemented on the machine and cannot be changed. For example,
VirtualMachine.Admin.UUID species the UUID of the machine, which cannot be changed.
n
External
A machine’s external properties are determined when the virtualization platform creates the machine or
during the WinPE phase of the build process. To set these properties, their values must be provided to
the proxy agent, which passes them on to the virtualization platform, or to the guest agent , which
implements them in the WinPE phase.
The specied value is implemented on the machine but is never updated. For example, if the property
VirtualMachine.Admin.AddOwnerToAdmins is set to true, the owner of the machine is added to its local
administrators group. If the owner is later removed from this group, the property is not updated to
false.
n
Updated
The specied value is implemented on the machine and is updated through data collection. For
example, if the compute resource of a machine is changed, a proxy agent updates the value of the
machine’s VirtualMachine.Admin.Hostname property.
Internal and read-only property types set aributes that the template determines.
You can use the vRealize Automation machine menu to change all reserved custom properties except the
read-only properties VirtualMachine.Admin.AgentID, VirtualMachine.Admin.UUID, and
VirtualMachine.Admin.Name.
