The fourth bullet in the slide notes states:
Guest agents – Guest agents are installed into virtual machines from the Update Manager server and are used in the scanning and remediation operations.Background Info:
The "VMware Update Manager 4.1 Administration Guide", on Chapter 5 "Installing the Guest Agent", page 39, explains that:
The VMware vCenter Update Manager Guest Agent facilitates Update Manager processes. For Linux and Windows operating systems, the Guest Agent is automatically installed the first time a patch remediation is scheduled or when a patch scan is initiated on a powered on virtual machine.Source:
VMware vCenter Update Manager 4.1 Installation and Administration Guide.Correct:
According to the VMware vCenter Update Manager 4.1 Release Notes:
Update Manager 4.1 and its subsequent update releases were the last releases of the product to support scanning and remediation of patches for Windows and Linux guest operating systems and applications running inside a virtual machine.
Hence it can be easily understood that, in Update Manager 5.x, the whole bullet mentioned above is simply not applicable.Source:
