A virtualization aware device management (VADM) server manages mobile devices, including mobile devices that have been virtualized. Each virtualized mobile device supports multiple virtual devices. Each virtual device can be managed independently by the VADM server, in similar manner to non-virtualized devices. The VADM server interacts with one or more device management clients (DMCs) running on a virtualized mobile device to manage the virtual devices installed thereon. In a mobile virtualized device, a DMC can run exclusively within the virtual machine monitor (VMM) for remote management of some or all of the virtual devices on the mobile virtualized device; within each virtual device for remote management of the respective virtual device; or a combination thereof, with a DMC in the VMM acting as a bridge for DMCs within the virtual devices.
