A hypervisor provides secure separation of multiple virtual machines on a device, thus removing conflicts when using the device for multiple purposes, including business and personal use. The hypervisor ensures security and privacy amongst the multiple virtual machines and prevents malicious attacks on one virtual machine from threatening another virtual machine. A switch provides a dedicated interface to the hypervisor, enabling secure switching between the multiple virtual machines. In addition, an indicator enables the hypervisor to identify an active virtual machine. Furthermore, the hypervisor hibernates inactive virtual machines in order to conserve power and provide another layer of protection against malicious attacks.
