In large infrastructures, there may be clusters of hosts that require patching. A full reboot would take quite a long time. Now, vSphere Lifecycle Manager (vLCM) has a quick boot option (a kind of a warm boot), which allows for a much smoother boot. Additionally, the “desired state” image of the cluster feature will ensure that new hosts that differ for some reason from the “image” will be remediated to the desired state.
