Abstract:
A sequence of programs enable execution of a guest operating system (OS) (116) installed on virtual hard disks (VHDs), one storing system, one storing user data (210, 212). The VHDs are stored on a storage device as for example a USB flash drive (216). The storage device is connected to a host system (110). Virtual machine monitor (VMM) (118) type, available RAM and an access path to an internal storage device (220) are detected. The guest OS (116) configuration is modified to support hardware emulated by the detected VMM. A virtual machine (VM) configuration for this VMM is created allocating a portion of the detected RAM for the VM (112). Both VHDs are attached as copy-on-write VHDs, and VM write operations to VHDs (210, 212) are redirected to overlay files (228, 230) on the host's internal storage device. After shutdown overlay files can be merged with corresponding VHD base files.
