Verify Prerequisites

The following prerequisites are required for virtual WOL to work:

Verify that the AM remote agent (RVI agent) is installed on a physical computer or on a virtual machine. Virtual WOLs are always performed from the computer that runs the AM remote agent.
Note: The RVI agent cannot collect certain BIOS inventory attributes from Linux virtual machines that are running on Microsoft Hyper-V and XenServer servers, Virtual WOL is not supported on such Linux virtual machines.
Verify that the scalability server is able to communicate to the AM remote agent computer. Virtual WOL requests are routed from the scalability server to the AM remote agent.
Verify that the AM remote agent has discovered and collected virtualization data from the VMs that you want to wake. The AM remote agent collects virtualization data through the inventory collection task. Until the inventory collection happens, a WOL operation assumes that the target computer is physical and not virtual. The inventory collection takes time depending on the number of VMs to be discovered and registered.

Note: Virtual WOL is not supported on guests running on the free version of VMware ESXi as the free version restricts API access to the host.
