Abstract

Systems and methods for creating new virtual machines based on post-boot virtual machine snapshots. An example method may include: receiving a request to create a new virtual machine, identifying, in view of the request, a virtual machine snapshot, the virtual machine snapshot including one or more elements of an initialized virtual machine, determining an update efficiency metric with respect to the virtual machine snapshot, and in response to a determination that the update efficiency metric reflects that updating the virtual machine snapshot is relatively more efficient than creating a new virtual machine in lieu of the virtual machine snapshot, creating the new virtual machine in view of the virtual machine snapshot.

First claim

What is claimed is:

1. A method comprising:
receiving a request to create a new virtual machine;
identifying, in view of the request, a virtual machine snapshot, the virtual machine snapshot comprising one or more elements of an initialized virtual machine;
simulating an update to the virtual machine snapshot to determine an update efficiency metric with respect to the virtual machine snapshot;
determining a second efficiency metric reflecting an efficiency associated with generating a new virtual machine without using the virtual machine snapshot;
comparing the update efficiency metric to the second efficiency metric; and
in response to a determination that the comparing reflects that the update to the virtual machine snapshot is relatively more efficient than generating the new virtual machine without using the virtual machine snapshot, creating, by a processing device, the new virtual machine in view of the virtual machine snapshot.

2. The method of claim 1 , wherein the one or more elements comprises a memory snapshot.

3. The method of claim 2 , further comprising updating the memory snapshot.

4. The method of claim 3 , wherein updating the memory snapshot comprises updating at least one of a time or a date stored in the memory snapshot.

5. The method of claim 3 , wherein updating the memory snapshot comprises adjusting a memory size.

6. The method of claim 3 , wherein creating the virtual machine comprises generating the virtual machine in view of the virtual machine snapshot and an update to the memory snapshot.

7. The method of claim 1 , wherein the virtual machine snapshot comprises a virtual machine that has undergone a boot process.

8. The method of claim 1 , wherein the virtual machine snapshot comprises a virtual machine having one or more applications running.

9. A system comprising:
a memory; and
a processing device, operatively coupled to the memory, to:
receive a request to create a new virtual machine;
identify, in view of the request, a virtual machine snapshot, the virtual machine snapshot comprising one or more elements of an initialized virtual machine;
simulate an update to the virtual machine snapshot to determine an update efficiency metric with respect to the virtual machine snapshot;
determine a second efficiency metric reflecting an efficiency associated with generation of a new virtual machine without using the virtual machine snapshot;
compare the update efficiency metric to the second efficiency metric; and
in response to a determination that the comparison reflects that the update to the virtual machine snapshot is relatively more efficient than generation of the new virtual machine without using the virtual machine snapshot, create the new virtual machine in view of the virtual machine snapshot.

10. The system of claim 9 , wherein the one or more elements comprises a memory snapshot.

11. The system of claim 10 , wherein the processing device is further to update the memory snapshot.

12. The system of claim 11 , wherein to update the memory snapshot the processing device is to update at least one of a time or a date stored in the memory snapshot.

13. The system of claim 11 , wherein to update the memory snapshot the processing device is to adjust a memory size.

14. The system of claim 11 , wherein to create the virtual machine the processing device is to generate the virtual machine in view of the virtual machine snapshot and an update to the memory snapshot.

15. The system of claim 9 , wherein the virtual machine snapshot comprises a virtual machine that has undergone a boot process.

16. The system of claim 9 , wherein the virtual machine snapshot comprises a virtual machine having one or more applications running.

17. A non-transitory computer-readable storage medium having instructions that, when executed by a processing device, cause the processing device to:
receive a request to create a new virtual machine;
identify, in view of the request, a virtual machine snapshot, the virtual machine snapshot comprising a memory snapshot;
update the memory snapshot;
simulate an update to the virtual machine snapshot to determine an update efficiency metric with respect to the virtual machine snapshot;
determine a second efficiency metric reflecting an efficiency associated with generation of a new virtual machine without using the virtual machine snapshot;
compare the update efficiency metric to the second efficiency metric; and
in response to a determination that the comparison reflects that the update to the virtual machine snapshot is relatively more efficient than generation of the new virtual machine without using the virtual machine snapshot, create, by the processing device, the new virtual machine in view of the virtual machine snapshot and an update to the memory snapshot.

18. The non-transitory computer-readable storage medium of claim 17 , wherein to update the memory snapshot the processing device is to update at least one of a time or a date stored in the memory snapshot.

19. The non-transitory computer-readable storage medium of claim 17 , wherein to update the memory snapshot the processing device is to adjust a memory size.

20. The non-transitory computer-readable storage medium of claim 17 , wherein the virtual machine snapshot comprises a virtual machine that has undergone a boot process.
