APPLICATION PARTITIONING ACROSS A VIRTUALIZED ENVIRONMENT
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.
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.
