Abstract

A processor including an execution core for executing instructions. In one embodiment, the instructions cause the core to enable two or more virtual machine guests to execute under the control of a virtual machine monitor. A first virtual machine guest includes a first portion of an application executing in the context of a first guest operating system. The first portion of the application creates a guest virtual machine applet that executes in the context of a second virtual machine guest. The first portion of the application and the guest virtual machine applet are part of a single application. To create a guest virtual machine applet, the first portion of the application executes a call to the first guest operating system and in response to receiving the call from the first portion of the application, the first guest operating system makes a system call to the virtual machine monitor.

Claims

1. A method comprising:

enabling two or more virtual machine guests to execute under the control of a virtual machine monitor;

a first virtual machine guest executing a first portion of an application in the context of a first guest operating system; and

the first portion of the application creating a guest virtual machine applet that executes in the context of a second virtual machine guest;

wherein the first portion of the application and the guest virtual machine applet are part of a single application.

2. The method of claim 1, wherein creating a guest virtual machine applet comprises:

the first portion of the application executing a call to the first guest operating system; and

in response to receiving the call from the first portion of the application, the first guest operating system making system calls to the virtual machine monitor.

3. The method of claim 1, wherein the guest virtual machine applet comprises executable code that is associated with the single application.

4. The method of claim 3, further comprising:

a second virtual machine guest executing a second portion of the application in the context of a second guest operating system; and

the first and second portions of the application sharing executable code within the guest virtual machine applet.

5. The method of claim 1, wherein the guest virtual machine applet comprises data storage that is associated with the single application.

6. The method of claim 5, further comprising:

a second virtual machine guest executing a second portion of the application in the context of a second guest operating system; and

the first and second portions of the application sharing data stored by the guest virtual machine applet.

7. The method of claim 1, wherein the guest virtual machine applet remains operating without interruption throughout a reboot of the first guest operating system.

8. A processor comprising:

an execution core configured to execute instructions to enable two or more virtual machine guests to execute under the control of a virtual machine monitor;

wherein a first virtual machine guest comprises a first portion of an application executing in the context of a first guest operating system;

wherein the first portion of the application is configured to create a guest virtual machine applet that executes in the context of a second virtual machine guest; and

wherein the first portion of the application and the guest virtual machine applet are part of a single application.

9. The processor of claim 8, wherein creating a guest virtual machine applet comprises:

the first portion of the application executing a call to the first guest operating system; and

in response to receiving the call from the first portion of the application, the first guest operating system making system calls to the virtual machine monitor.

10. The processor of claim 8, wherein the guest virtual machine applet comprises executable code that is associated with the single application.

11. The processor of claim 10,

wherein a second virtual machine guest is configured to execute a second portion of the application in the context of a second guest operating system;

and

the first and second portions of the application share executable code within the guest virtual machine applet.

12. The processor of claim 8, wherein the guest virtual machine applet comprises data storage that is associated with the single application.

13. The processor of claim 12,

wherein a second virtual machine guest is configured to execute a second portion of the application in the context of a second guest operating system;

and

the first and second portions of the application share data stored by the guest virtual machine applet.

14. The processor of claim 8, wherein the guest virtual machine applet remains operating without interruption throughout a reboot of the first guest operating system.

15. A computer accessible storage medium storing a plurality of instructions which, when executed, cause an execution core of a processor to:

enable two or more virtual machine guests to execute under the control of a virtual machine monitor;

wherein a first virtual machine guest comprises a first portion of an application executing in the context of a first guest operating system;

wherein the first portion of the application is configured to create a guest virtual machine applet that executes in the context of a second virtual machine guest; and

wherein the first portion of the application and the guest virtual machine applet are part of a single application.

16. The computer accessible storage medium of claim 15, wherein creating a guest virtual machine applet comprises:

the first portion of the application executing a call to the first guest operating system; and

in response to receiving the call from the first portion of the application, the first guest operating system making system calls to the virtual machine monitor.

17. The computer accessible storage medium of claim 15, wherein the guest virtual machine applet comprises executable code that is associated with the single application.

18. The computer accessible storage medium of claim 17,

wherein a second virtual machine guest is configured to execute a second portion of the application in the context of a second guest operating system;

and

the first and second portions of the application share executable code within the guest virtual machine applet.

19. The computer accessible storage medium of claim 15, wherein the guest virtual machine applet comprises data storage that is associated with the single application.

20. The computer accessible storage medium of claim 19,

wherein a second virtual machine guest is configured to execute a second portion of the application in the context of a second guest operating system;

and

the first and second portions of the application share data stored by the guest virtual machine applet.
