Multi-mode mobile computer with hypervisor affording diskless and local disk operating environments
A mobile device, such as a laptop or notebook computer, capable of booting from at least two environments. If a remote environment is present, the mobile device may boot from the remote environment. The mobile device may also boot from the local environment.
1. A system comprising:
a mobile device; and
a hypervisor loaded in said mobile device;
said hypervisor acting to afford a first mode of operation of said mobile device and a second mode of operation of said mobile device, the first mode of operation being associated with a diskless operating environment and the second mode of operation being associated with a local disk operating environment
wherein said hypervisor, responsive to one or more predetermined criteria, is configured to hibernate the first mode of operation and afford the second mode of operation.
2. The system according to claim 1 , wherein said hypervisor acts to afford diskless operation in said first mode of operation responsive to a determination that a needed network connection is available.
3. The system according to claim 1 , wherein the first mode of operation is associated with an external environment.
4. The system according to claim 3 , wherein the external environment is an external network.
5. The system according to claim 1 , wherein said hypervisor acts to afford local operation in said second mode of operation responsive to a determination that a needed network connection is not available.
6. The system according to claim 1 , wherein the second mode of operation is associated with a local environment.
7. The system according to claim 6 , wherein:
said mobile device comprises an operating system;
said local environment comprises said operating system.
8. The system according to claim 7 , wherein:
said mobile device further comprises a hard disk drive;
said local environment further comprises said hard disk drive.
9. The system according to claim 1 , wherein said hypervisor further acts to afford a third mode of operation of said mobile device, the third mode of operation being associated with both of the diskless and local disk operating environments.
10. The system according to claim 9 , wherein the diskless operating environment is an external environment and the local disk operating environment is a local environment.
11. The system according go claim 10 , wherein said hypervisor acts to accept input from the external environment for use in the local environment.
12. A method comprising:
loading a hypervisor in a mobile device;
with the hypervisor, affording a first mode of operation of the mobile device and a second mode of operation of the mobile device, the first mode of operation being associated with a diskless operating environment and the second mode of operation being associated with a local disk operating environment; and
with said hypervisor responsive to one or more predetermined criteria hibernating the first mode of operation and affording the second mode of operation.
13. The method according to claim 12 , wherein said affording a first mode of operation comprises affording diskless operation responsive to a determination that a needed network connection is available.
14. The method according to claim 12 , wherein the first mode of operation is associated with an external network.
15. The method according to claim 12 , wherein said affording of a second mode of operation comprises affording local operation responsive to a determination that a needed network connection is not available.
16. The method according to claim 12 , wherein the second mode of operation is associated with an operating system of the mobile device.
17. The method according to claim 16 , wherein the second mode of operation is further associated with a hard disk drive of the mobile device.
18. The method according to claim 12 , further comprising, with the hypervisor, affording a third mode of operation of the mobile device, the third mode of operation being associated with both of the diskless and local disk operating environments.
19. The method according to claim 18 , wherein:
the diskless operating environment is an external environment and the local disk operating environment is a local environment; and
said affording of a third mode of operating comprises accepting input from the external environment for use in the local environment.
20. A non-transitory program storage device readable by machine embodying a program of instructions executable by the machine to perform steps comprising:
loading a hypervisor in a mobile device;
with the hypervisor, affording a first mode of operation of the mobile device and a second mode of operation of the mobile device, the first mode of operation being associated with a diskless operating environment and the second mode of operation being associated with a local disk operating environment; and
with said hypervisor, responsive to one or more predetermined criteria, hibernating the first mode of operation and affording the second mode of operation.
