The VM Platform Layer
Virtual desktop groups consist of virtual desktops that are pooled, pre-assigned, or assigned on first use. Each group can contain only one type of desktop. These virtual desktops can run on PCs, blades, or virtual machines (VMs) provided through a virtualization infrastructure. For every group, this layer reports the availability of the server that hosts the virtual desktops in the group.
