Abstract

A system, computer readable medium and method for merging a first virtual machine and a second virtual machine that runs on a same or different physical machine. The method includes a step of receiving instructions for merging processes of the first virtual machine with processes of the second virtual machine; a step of merging the first virtual machine with the second virtual machine onto a first physical machine; a step of merging an operating system of the first virtual machine with an operating system of the second virtual machine onto the first physical machine; and a step of maintaining active in the merged virtual machine each process that was active prior to merging the first and second virtual machines.

First claim

What is claimed is:

1. A method for merging a first virtual machine and a second virtual machine that run on a same or different physical machines, the method comprising:
receiving instructions for merging processes of the first virtual machine with processes of the second virtual machine;
merging the first virtual machine with the second virtual machine onto a first physical machine;
after the virtual machines are merged, merging an operating system of the first virtual machine, which 1) executes a first set of applications and 2) is a particular type of operating system, with an operating system of the second virtual machine, which 1) executes a second set of applications and 2) is of the same type as the operating system of the first virtual machine, onto the first physical machine such that the merged operating system executes all of the applications from the first and second sets of applications;
determining, for each process running on the first virtual machine that has an identical process running on the second virtual machine, which of the identical processes is more advanced, wherein determining which process is more advanced is based on which process has downloaded a greater portion of a file;
selecting the process that was determined to be more advanced from the identical processes to run on the merged virtual machine; and
maintaining active in the merged virtual machine, after the first and second virtual machines have finished merging, the selected process and all processes that did not have an identical process that were active prior to merging the first and second virtual machines.

2. The method of claim 1 , further comprising:
migrating the second virtual machine together with its corresponding processes from a second physical machine to the first physical machine.

3. The method of claim 2 , further comprising:
running the plural processes while migrating the second virtual machine.

4. The method of claim 2 , wherein the first physical machine is a mobile phone, a laptop, a tablet or a mobile computing device while the second physical machine is a server or a fixed computing device.

5. The method of claim 2 , wherein the first physical machine has less computational power than the second physical machine.

6. The method of claim 1 , wherein the step of receiving instructions comprises:
receiving instructions from a user;
receiving instructions from a file stored in the first or second virtual machine;
receiving instructions from an application that runs on the first or second virtual machine; or
receiving instructions from the operating system of the first or second virtual machine, a network, or hardware.

7. The method of claim 1 , further comprising:
running the plural processes while merging the first and second virtual machines.

8. The method of claim 1 , further comprising:
stopping the processes while merging the first and second virtual machines.

9. The method of claim 1 , further comprising:
generating the first virtual machine by an underlying virtualization engine communicatively coupled to the first physical machine while running on the first physical machine.

10. A computing machine comprising:
a processor configured to run a virtualization engine that creates a first virtual machine to run on the computing machine; and
an interface connected to the processor and configured to receive instructions for merging processes of the first virtual machine with processes of a second virtual machine,
wherein the processor is configured to:
merge the first virtual machine with the second virtual machine onto the first physical machine,
after the virtual machines are merged, merge an operating system of the first virtual machine, which 1) executes a first set of applications and 2) is a particular type of operating system, with an operating system of the second virtual machine, which 1) executes a second set of applications and 2) is of the same type as the operating system of the first virtual machine, onto the first physical machine such that the merged operating system executes all of the applications from the first and second sets of applications;
determine, for each process running on the first virtual machine that has an identical process running on the second virtual machine, which of the identical processes is more advanced, wherein determining which process is more advanced is based on which process has downloaded a greater portion of a file;
select the process that was determined to be more advanced from the identical processes to run on the merged virtual machine; and
maintain active in the merged virtual machine, after the first and second virtual machines have finished merging, the selected process and all processes that did not have an identical process that were active prior to merging the first and second virtual machines.

11. The computing machine of claim 10 , wherein the virtualization engine is configured to:
receive on the first physical machine the second virtual machine together with its corresponding processes from a second physical machine.

12. The computing machine of claim 11 , further comprising:
running the plural processes while migrating the second virtual machine.

13. The computing machine of claim 11 , wherein the first physical machine is a mobile phone, a laptop, a tablet or a mobile computing device while the second physical machine is a server or a fixed computing device.

14. The computing machine of claim 11 , wherein the first physical machine has less computational power than the second physical machine.

15. The computing machine of claim 10 , wherein the step of receiving instructions comprises:
receiving instructions from a user;
receiving instructions from a file stored in the virtual machine;
receiving instructions from an application that runs on the virtual machine; or
receiving instructions from the operating system, a network or hardware.

16. The computing machine of claim 10 , further comprising:
running the plural processes while merging the first and second virtual machines.

17. A computing system comprising:
a first physical machine that includes:
a processor configured to run a virtualization engine that creates a first virtual machine to run on the first physical machine; and
an interface connected to the processor and configured to receive instructions for merging processes of the first virtual machine with processes of a second virtual machine, wherein the virtualization engine is configured to:
merge the first virtual machine with the second virtual machine onto the first physical machine,
after the virtual machines are merged, merge an operating system of the first virtual machine, which 1) executes a first set of applications and 2) is a particular type of operating system, with an operating system of the second virtual machine, which 1) executes a second set of applications and 2) is of the same type as the operating system of the first virtual machine, onto the first physical machine such that the merged operating system executes all of the applications from the first and second sets of applications;
determine, for each process running on the first virtual machine that has an identical process running on the second virtual machine, which of the identical processes is more advanced, wherein determining which process is more advanced is based on which process has downloaded a greater portion of a file;
select the process that was determined to be more advanced from the identical processes to run on the merged virtual machine; and
maintain active in t
