7.3

There are exceptions to the precedence rules. For example, you add the
VMware.VirtualCenter.Folder custom property to a business group, provide a property value, and do
not select the option to show the property in the request. You add the same custom property to a blueprint
and specify that the property be shown in the request. When your designated users request provisioning
from the catalog, the property does not appear in the catalog request form because the property applies
to reservation information that is only available after provisioning begins, and not when you request
provisioning.
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 specified 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 effect on the machine.
n
Read-only
The specified value is implemented on the machine and cannot be changed. For example,
VirtualMachine.Admin.UUID specifies 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 specified 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 specified 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 attributes 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.
