Abstract

A system to improve a user-space environment may include a user-space configured to execute on an operating system-level virtualization. The system may also include a boot module configured to boot up the user-space on the operating system-level virtualization without disrupting the operating system-level virtualization even if the operating system-level virtualization is already running.

Claims

1. A system comprising:

a user-space configured to execute on an operating system-level virtualization; and

a boot module configured to boot up the user-space on the operating system-level virtualization without disrupting the operating system-level virtualization even if the operating system-level virtualization is already running.

2. The system of claim 1 wherein the operating system-level virtualization executes on a first physical device;

and wherein the boot module executes on a second physical device.

3. The system of claim 1 wherein the boot module comprises a root volume group.

4. The system of claim 1 wherein the boot module comprises logical volume names that substantially match operating system-level virtualization logical volume names.

5. The system of claim 2 wherein the user-space executes processes based upon images on the second physical device.

6. The system of claim 1 wherein the user-space is associated with a physical storage device and a root volume group that is based upon the user-space.

7. The system of claim 6 wherein the root volume group comprises user-space core file systems provided from the operating system-level virtualization.

8. The system of claim 2 wherein the boot module comprises object data manager data and second physical device data.

9. The system of claim 8 wherein the object data manager data and second physical device data are at least one of used and updated when the first physical device is configured during the boot up.

10. A method comprising:

executing a user-space on an operating system-level virtualization; and

booting up the user-space on the operating system-level virtualization without disrupting the operating system-level virtualization even if the operating system-level virtualization is already running.

11. The method of claim 10 further comprising executing the operating system-level virtualization on a first physical device and the boot module on a second physical device.

12. The method of claim 10 further comprising substantially matching logical volume names on the boot module with operating system-level virtualization logical volume names.

13. The method of claim 10 further comprising executing user-space processes based upon images on the second physical device.

14. The method of claim 10 further comprising associating the user-space with a physical storage device and a root volume group that is based upon the user-space.

15. The method of claim 10 further comprising providing from the operating system-level virtualization a root volume group that includes user-space core file systems.

16. The method of claim 11 further comprising at least one of using and updating object data manager data and physical storage device data when the first physical device is configured during the boot up.

17. A computer program product to improve a user-space, the computer program product comprising:

a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising;

computer readable program code configured to execute a user-space on an operating system-level virtualization; and

computer readable program code configured to boot up the user-space on the operating system-level virtualization without disrupting the operating system-level virtualization even if the operating system-level virtualization is already running.

18. The computer program product of claim 17 further comprising computer readable program code configured to execute the operating system-level virtualization on a first physical device and the boot module on a second physical device, and to at least one of use and update object data manager data and second physical device data when the first physical device is configured during the boot up.

19. The computer program product of claim 17 further comprising computer readable program code configured to substantially match logical volume names on the boot module with operating system-level virtualization logical volume names.

20. The computer program product of claim 17 further comprising computer readable program code configured to execute user-space processes based upon images on the second physical device.

21. The computer program product of claim 17 further comprising computer readable program code configured to associate the user-space with a physical storage device and a root volume group that is based upon the user-space.

22. The computer program product of claim 17 further comprising computer readable program code configured to provide from the operating system-level virtualization a root volume group that includes user-space core file systems.

23. The computer program product of claim 17 further comprising computer readable program code configured to at least one of use and update object data manager data and second physical device data when the second physical device is configured during the boot up.

24. A system comprising:

a user-space configured to execute on an operating system-level virtualization when executing on a first physical device; and

a boot module configured to execute on a second physical device and boot up the user-space on the operating system-level virtualization without disrupting the operating system-level virtualization even if the operating system-level virtualization is already running, and the boot module includes logical volume names that substantially match operating system-level virtualization logical volume names.

25. The system of claim 24 wherein the user-space executes processes based upon images on the second physical device.
