Abstract: Certain aspect of the present disclosure relates to a virtual machine (VM) control system, which includes a VM controller. For a plurality of employees, the VM controller registers each employee by assigning an employee ID, and stores registration information in an attendance database. The VM controller also associates one or more VMs to each employee, and stores VM association information between the VMs and the employees in an employee ID database. The VM controller transmits polling inquiries periodically to the attendance database to retrieve employee presence events of the employees. For each employee, the employee presence events include an ingress event and an egress event. When the ingress event is detected and the associated VM is off, the VM controller launches the associated VM. When the egress event is detected and the associated VM is on, the VM controller shuts down the associated VM.
