System, method, and computer-readable medium for virtual machine instantiation from an external peripheral device
View Patent ↗A system, method, and computer-readable medium for instantiating a virtual machine on a computer by way of a physical peripheral device is provided. A virtual machine image may be composed on a portable memory device, such as a USB-flash memory device. Insertion of the physical device in a peripheral terminal is detected by a host function or module, and the physical device is evaluated to determine whether a virtual machine is defined thereby. In the event that the physical device includes a virtual machine image, the host reads the virtual machine image from the physical device and allocates a virtual machine per the read virtual machine image.
1. A method of instantiating a virtual machine, comprising:
detecting attachment of a physical peripheral device to a peripheral terminal;
evaluating the physical peripheral device to determine if a virtual machine image is composed thereon;
responsive to determining the physical peripheral device has the virtual machine image composed thereon, reading the virtual machine image from the physical peripheral device; and
instantiating a first virtual machine according to the virtual machine image,
wherein the instantiating includes allocating an instance of an operating system and one or more applications each defined by the virtual machine image.
2. The method of claim 1 , further comprising allocating resources to the first virtual machine.
3. The method of claim 1 , wherein detecting attachment further comprises detecting attachment of a universal serial bus physical peripheral device.
4. A device that facilitates instantiation of a virtual machine, comprising:
a peripheral bus interface through which the device is coupled to an external host device, wherein attachment of the device is detected by the external host device;
a peripheral bus controller that facilitates communication with the external host device; and
a memory having an image of a virtual machine composed thereon, wherein the external host device is adapted to read the image of the virtual machine from the memory, wherein the image of the virtual machine is different from the virtual machine itself and is operable to be used to instantiate the virtual machine in the external host device by allocating an instance of an operating system and one or more applications each defined by the image of the virtual machine.
5. The device according to claim 4 , wherein the peripheral bus interface comprises a universal serial bus interface, and wherein the peripheral bus controller comprises a universal serial bus controller.
6. An apparatus comprising a non-transitory, tangible computer-readable storage medium storing computer-executable instructions for execution by a processing system, the computer-executable instructions for instantiating a virtual machine and include:
instructions that detect attachment of a physical peripheral device to a peripheral terminal;
instructions that evaluate the physical peripheral device to determine if a virtual machine image is composed thereon;
instructions that, responsive to a determination that the physical peripheral device has the virtual machine image composed thereon, read the virtual machine image from the physical peripheral device; and
instructions that instantiate a first virtual machine according to the virtual machine image, wherein the instructions that instantiate further include instructions that allocate an instance of an operating system and one or more applications each defined by the virtual machine image.
7. The apparatus according to claim 6 , wherein the computer-readable storage medium stores further instructions that allocate resources to the first virtual machine.
8. The apparatus of claim 6 , wherein the instructions that detect attachment further include instructions that detect attachment of a universal serial bus physical peripheral device.
9. A computer system, comprising:
a memory system having a first operating system and a virtualization manager running thereon;
a processor system coupled with the memory system; and
a peripheral bus system adapted for attachment of one or more peripheral devices, wherein the virtualization manager is adapted to, in response to attachment of a physical peripheral device to the peripheral bus system, read a virtual machine image from the physical peripheral device and instantiate a first virtual machine in the memory system according to the virtual machine image.
10. The system of claim 9 , wherein the first virtual machine comprises an operating system instance and one or more applications defined by the virtual machine image.
11. The system of claim 9 , wherein the peripheral bus system comprises a universal serial bus, and wherein the physical peripheral device comprises a universal serial bus physical device.
12. The system of claim 9 , further comprising a virtualization daemon allocated in the memory system that is adapted to detect attachment of the physical peripheral device to the peripheral bus system.
13. The system of claim 12 , wherein the virtualization daemon, in response to detecting attachment of the physical peripheral device, evaluates the physical peripheral device for inclusion of the virtual machine image.
14. The system of claim 9 , wherein the physical peripheral device comprises a universal serial bus flash memory device.
15. The system of claim 9 , wherein the one or more peripheral devices comprise a plurality of peripheral devices each having a respective virtual machine image composed thereon, and wherein the virtualization manager is adapted to instantiate a virtual machine in the memory system for each respective virtual machine image.
16. The method of claim 1 , wherein the instantiating is carried out in a manner so that the first virtual machine is instantiated in a host device that is different from the physical peripheral device; and wherein the virtual machine image is different from the first virtual machine.
17. The device of claim 4 , wherein the device is a portable device.
18. The apparatus of claim 6 , wherein the instructions that instantiate the first virtual machine include instructions that instantiate the first virtual machine in a host device that is different from the physical peripheral device, and wherein the first virtual machine is different from the virtual machine image.
