Abstract
A host controller pre-schedules the timelines of virtual machines that run on a host cluster. In one embodiment, the host controller uses a plurality of timers to determine the start times of the virtual machines. The host controller starts the virtual machines on the host cluster over a time span according to the configurable timelines recorded in the timers. The start times of the virtual machines can be spread over the time span to prevent a load spike at any particular time instance. The virtual machines are up and running on the hosts by a pre-determined time to provide virtual desktops to remote clients. The timers may be configured as a calendar.
