20100235831 | Method for dynamic configuration of virtual machine - A set of programs enable the start and the efficient and secure operation of an operating system (OS) installed on a virtual hard disk that is stored on an external storage device. When the external storage device is connected to a host system, a user can start the OS in a virtual machine on the host system. The virtual machine execution is controlled by a virtual machine monitor (VMM) installed on the host system. At startup of the program, the type of VMM installed on the host system is autodetected. Host system parameters that are relevant for an optimal configuration of the virtual machine, such as the amount of available physical memory, are captured. Before launch of the virtual machine the OS installed on the virtual hard disk is dynamically modified to support hardware emulated by the selected VMM. Configuration templates and scripts for supported VMM types are stored on the external storage device. The template or script that corresponds to the autodetected VMM is used to create an optimized virtual machine configuration. Virtual machine configuration parameters that depend upon host settings are adapted. The created virtual machine configuration includes a specific storage configuration: The virtual machine is configured to use three virtual hard disks for system, user, and paging data. The virtual hard disks for system and user data are configured to use copy-on-write (COW) functionality supported by the respective VMM. With the COW configuration the virtual machine's write operations are redirected to a location in a file system on an internally attached storage medium. The non-persistent virtual hard disk used for the page data is entirely stored in the temporary location as an expanding virtual hard disk and is erased after shutdown. If data persistence is required for user and/or system data the respective overlay files are merged with the corresponding virtual hard disk base files on the external storage device after shutdown of the virtual machine. When the program managing the configuration and launch process is closed after shutdown of the virtual machine, all temporary files are deleted. The dynamic COW configuration with deferred, consolidated write operations to the external storage device offers the benefits of improved write performance and security and extended lifetime of the external storage device. The latter is particularly important for flash-memory-based devices with a finite number of sustainable write/erase cycles per storage block. | 09-16-2010 |
