1. A method comprising: measuring a graphics load associated with graphics operations of a computing device in view of a number of graphics operations performed by the computing device before a deployment of a virtual desktop system; estimating a capacity of the virtual desktop system to be deployed in view of the measured graphics load associated with the graphics operations of the computing device; determining, by a processing device, a capacity of a host system to provide graphics operations by using the estimated capacity of the virtual desktop system, wherein the host system is associated with one or more virtual machines providing one or more virtual desktop systems, and wherein the capacity of the host system specifies a number of the one or more virtual desktop systems that the host system is to support; and determining, before the deployment of the virtual desktop system, a number of additional host systems to deploy when the number of the one or more virtual desktop systems that the host system is to support exceeds the capacity of the host system.
