PORTABLE VIRTUAL APPLICATIONS
In accordance with the present disclosure, a method for operating a virtual application comprises loading an image of the virtual application into a memory of an information handling system from a deployment package is disclosed. A shared library that is required for executing the virtual application is loaded. An address for a memory location corresponding to an entry point for a function in the shared library is saved to an address table for the virtual application. The virtualization data from the deployment package is used to determine whether the address for the memory location corresponding to the entry point for a function in the shared library should be adjusted.
1 . A method for operating a virtual application comprising:
loading an image of the virtual application into a memory of an information handling system from a deployment package;
loading a shared library required for executing the virtual application;
saving an address for a memory location corresponding to an entry point for a function in the shared library to an address table for the virtual application; and
determining whether the address for the memory location corresponding to the entry point for the function in the shared library should be adjusted based upon a virtualization data from the deployment package.
2 . The method of claim 1 , wherein the shared library is loaded by a loader provided by an operating system.
3 . The method of claim 2 , wherein the shared library is loaded from the deployment package.
4 . The method of claim 3 , wherein the shared library is loaded at run-time.
5 . The method of claim 2 , wherein the shared library is loaded based upon information from a compatibility layer of an operating system.
6 . The method of claim 1 , wherein the shared library is loaded by a loader provided in the deployment package.
7 . The method of claim 6 , wherein the shared library is loaded from the deployment package.
8 . The method of claim 7 , wherein the shared library is loaded at run-time.
9 . A non-transitory computer-readable storage medium with an executable file stored thereon, wherein the file causes a microprocessor to perform the following steps:
loading an image of a virtual application into a memory of an information handling system from a deployment package;
loading a shared library required for executing the virtual application;
saving an address for a memory location corresponding to an entry point for a function in the shared library to an address table for the virtual application; and
determining whether the address for the memory location corresponding to the entry point for the function in the shared library should be adjusted based upon a virtualization data from the deployment package.
10 . The non-transitory computer-readable storage medium of claim 9 , wherein the shared library is loaded by a loader provided by an operating system.
11 . The non-transitory computer-readable storage medium of claim 10 , wherein the shared library is loaded from the deployment package.
12 . The non-transitory computer-readable storage medium of claim 11 , wherein the shared library is loaded at run-time.
13 . The non-transitory computer-readable storage medium of claim 10 , wherein the shared library is loaded based upon information from a compatibility layer of an operating system.
14 . The non-transitory computer-readable storage medium of claim 9 , wherein the shared library is loaded by a loader provided in the deployment package.
15 . The non-transitory computer-readable storage medium of claim 14 , wherein the shared library is loaded from the deployment package.
16 . The non-transitory computer-readable storage medium of claim 15 , wherein the shared library is loaded at run-time.
17 . A process for creating a virtual application comprising:
creating an image of a virtual application from an application executing on an information handling system;
saving the image of the virtual application to a deployment package;
identifying a shared library required for executing the virtual application;
saving an address for a memory location corresponding to an entry point for a function in the shared library to an address table in the image of the virtual application; and
saving the deployment package formatted in an executable file format to a non-transitory computer-readable storage medium.
18 . The process for creating a virtual application of claim 17 , comprising:
saving an image of the shared library to the deployment package.
19 . The non-transitory computer-readable storage medium of claim 17 .
20 . The non-transitory computer-readable storage medium of claim 18 .
