Abstract

A method, apparatus, and system are disclosed for configuring an operating system on a target computer. A configuration module configures a target computer as a diskless client. A boot module boots the target computer to a setup state. A communication module establishes communications between the target computer, a donor storage device of a donor computer, and a virtual disk. A copy module copies a configuration image from the donor storage device to the virtual disk. The configuration image comprises an operating system and a software configuration installed on the donor computer. A modification module modifies the configuration image on the virtual disk to conform to a hardware configuration of the target computer.

Claims

1. A computer readable storage medium comprising a computer readable program:

stored on a tangible storage device for configuring an operating system on a target computer, wherein the computer readable program when executed on at least one computer causes the at least one computer to;

configure a target computer as a diskless client;

boot the target computer to a setup state;

establish communications between the target computer, a donor storage device of a donor computer, and a virtual disk;

copy a configuration image from the donor storage device to the virtual disk, the configuration image comprising an operating system and a software configuration installed on the donor computer; and

modify the configuration image on the virtual disk to conform to a hardware configuration of the target computer.

2. The computer readable storage medium of claim 1, wherein a hardware configuration of the donor computer is equivalent to the hardware configuration of the target computer plus the donor storage device.

3. The computer readable storage medium of claim 1, wherein the configuration image further comprises partitioning and file system information for the donor storage device.

4. The computer readable storage medium of claim 1, wherein the computer readable program further causes the at least one computer to boot the target computer from a Compact Disk (CD).

5. The computer readable storage medium of claim 1, wherein the computer readable program further causes the at least one computer to boot the target computer over a network.

6. The computer readable storage medium of claim 1, wherein the setup state comprises a pre-install environment.

7. The computer readable storage medium of claim 1, wherein the configuration image comprises an operating system registry.

8. The computer readable storage medium of claim 7, wherein the target computer in the setup state creates a hardware profile for the target computer hardware configuration.

9. The computer readable storage medium of claim 8, wherein the computer readable program further causes the at least one computer to modify the configuration image on the virtual disk by:

creating an injection scheme from the hardware profile, the injection scheme comprising device drivers and changes to the operating system registry conforming to the target computer hardware configuration; and

copying the injection scheme to the virtual disk.

10. The computer readable storage medium of claim 1, wherein the computer readable program further causes the at least one computer to modify configuration options by presenting the configuration options to a user and receiving modifications to the configuration options from the user.

11. The computer readable storage medium of claim 1, wherein the computer readable program further causes the at least one computer to:

boot the target computer;

download a hypervisor to the target computer;

install the hypervisor on the target computer; and

present the virtual disk as a target computer non-volatile storage device.

12. The computer readable storage medium of claim 11, wherein the computer readable program further causes the at least one computer to download the hypervisor over an Internet Small Computer System Interface (iSCSI) network.

13. An apparatus comprising:

a configuration module configuring a target computer as a diskless client;

a boot module booting the target computer to a setup state;

a communication module establishing communications between the target computer, a donor storage device of a donor computer, and a virtual disk;

a copy module copying a configuration image from the donor storage device to the virtual disk, the configuration image comprising an operating system and a software configuration installed on the donor computer; and

a modification module modifying the configuration image on the virtual disk to conform to a hardware configuration of the target computer.

14. The apparatus of claim 13, wherein a hardware configuration of the donor computer is equivalent to the hardware configuration of the target computer plus the donor storage device and the configuration image further comprises partitioning and file system information for the donor storage device.

15. The apparatus of claim 13, wherein the setup state comprises a pre-install environment, the configuration image comprises an operating system registry, the target computer in the setup state creates a hardware profile for the target computer hardware configuration.

16. The apparatus of claim 15, wherein the modification module modifies the configuration image on the virtual disk to conform to a hardware configuration of the target computer by:

creating an injection scheme from the hardware profile, the injection scheme comprising device drivers and changes to the operating system registry conforming to the target computer hardware configuration; and

copying the injection scheme to the virtual disk.

17. A system comprising:

a target computer;

a donor computer comprising a donor storage device, wherein a hardware configuration of the donor computer is equivalent to a hardware configuration of the target computer plus the donor storage device;

a virtual disk organized on a storage device;

a network;

a configuration module configuring the target computer as a diskless client;

a boot module booting the target computer to a setup state;

a communication module establishing communications between the target computer, the donor storage device, and the virtual disk over the network;

a copy module copying a configuration image from the donor storage device to the virtual disk, the configuration image comprising an operating system and a software configuration installed on the donor computer; and

a modification module modifying the configuration image on the virtual disk to conform to a hardware configuration of the target computer.

18. The system of claim 17,

the boot module further booting the target computer;

and

the communication module further downloading a hypervisor to the target computer, installing the hypervisor on the target computer, and presenting the virtual disk as a target computer non-volatile storage device.

19. The system of claim 17, wherein the configuration image further comprises partitioning and file system information for the donor storage device.

20. The system of claim 17, wherein the setup state comprises a pre-install environment, the configuration image comprises an operating system registry, and the target computer in the setup state creates a hardware profile for the target computer hardware configuration.
