Abstract

In a method for providing an application by a virtual machine (VM), an application requesting instruction for requesting a target application is received from a client. An available VM is assigned according to the application requesting instruction. A target-application executable file corresponding to the target application is searched from several candidate executable files stored in an executable-file storage pool. The target-application executable file is mounted to the available VM. The mounted target-application executable file is executed through the available VM.

(d) mounting the target-application executable file to the available VM; and

(e) executing the mounted target-application executable file through the available VM.

2. The method for providing an application by a VM of claim 1, wherein an application installed on the client generates and transmits the application requesting instruction, a virtual desktop is provided to the client to generate and transmit the application requesting instruction, or a web page is provided to the client to generate and transmit the application requesting instruction.

3. The method for providing an application by a VM of claim 1, further comprising:

providing a plurality of candidate VMs,

wherein each of the candidate VMs is allocated with a corresponding resource, and

wherein the assigning at operation (b) is performed according to a result of determining if the corresponding resources of the candidate VMs are adequate for mounting and executing the target-application executable file.

4. The method for providing an application by a VM of claim 3, wherein:

each of the candidate VMs further comprises an installed application;

the assigning at operation (b) is performed according to a result of determining if the installed applications of the candidate VMs comprise the target application and if the corresponding resources of the candidate VMs are adequate for executing the target-application executable file; and

when all of the corresponding resources of the candidate VMs, the installed applications of which comprise the target application, are not adequate for executing the target-application executable file, the assigning at operation (b) is performed according to a result of determining if the corresponding resources of the candidate VMs, the installed applications of which do not comprise the target application, are adequate for executing the target-application executable file.

5. The method for providing an application by a VM of claim 3, wherein the candidate executable files stored in the executable-file storage pool are executable within a VM environment of each of the candidate VMs.

6. The method for providing an application by a VM of claim 1 further comprising:

displaying an executing image generated by the available VM during executing the target-application executable file on a display unit of the client.

7. The method for providing an application by a VM of claim 1, wherein operation (b) comprises:

determining a requested resource for the target application according to the application requesting instruction; and

selecting the available VM, which has a resource adequate for the requested resource, from a plurality of candidate VMs.

8. The method for providing an application by a VM of claim 7 further comprising:

monitoring a remaining resource of each of the candidate VMs;

wherein selecting the available VM, which has the resource adequate for the requested resource, from the candidate VMs comprises;

selecting one of the candidate VMs, the remaining resource of which is adequate for the requested resource, as the available VM.

9. The method for providing an application by a VM of claim 1, wherein operation (d) comprises:

linking or copying the target-application executable file to a shared space from the executable-file storage pool; and

mounting the target-application executable file in the shared space.

10. The method for providing an application by a VM of claim 1, further comprising before operation (a):

mounting a plurality of preset application executable files to the available VM; and

determining if the preset application executable files comprise the target-application executable file;

wherein if the preset application executable files do not comprise the target-application executable file, operation (d) is performed; and

wherein if the preset application executable files comprise the target-application executable file, operation (d) is not performed.

11. A system for providing an application by a VM comprising:

an executable-file storage pool for storing a plurality of candidate executable files;

an instruction receiving module for receiving an application requesting instruction for requesting a target application from a client;

a VM assigning module for assigning an available VM according to the application requesting instruction;

an executable-file searching module for searching a target-application executable file corresponding to the target application from the candidate executable files stored in the executable-file storage pool; and

a mounting module for mounting the target-application executable file to the available VM, such that the available VM executes the mounted target-application executable file.

12. The system for providing an application by a VM of claim 11, wherein an application installed on the client generates and transmits the application requesting instruction, a virtual desktop is provided to the client to generate and transmit the application requesting instruction, or a web page is provided to the client to generate and transmit the application requesting instruction.

13. The system for providing an application by a VM of claim 11, further comprising:

a plurality of candidate VMs, wherein each of the candidate VMs is allocated with a corresponding resource;

wherein the VM assigning module assigns the available VM according to a result of determining if the corresponding resources of the candidate VMs are adequate for mounting and executing the target-application executable file.

14. The system for providing an application by a VM of claim 13, wherein:

each of the candidate VMs further comprises an installed application;

the VM assigning module assigns the available VM according to a result of determining if the installed applications of the candidate VMs comprise the target application and if the corresponding resources of the candidate VMs are adequate for executing the target-application executable file; and

when all of the corresponding resources of the candidate VMs, the installed applications of which comprise the target application, are not adequate for executing the target-application executable file, the VM assigning module assigns the available VM according to a result of determining if the corresponding resources of the candidate VMs, the installed applications of which do not comprise the target application, are adequate for executing the target-application executable file.

15. The system for providing an application by a VM of claim 11, wherein the mounting module provides an executing image generated by the available VM during executing the target-application executable file, such that a display unit of the client displays the executing image.

16. The system for providing an application by a VM of claim 11, further comprising:

an information determining module for determining a requested resource for the target application according to the application requesting instruction;

wherein the VM assigning module selects one of the candidate VMs, which has a resource adequate for the requested resource, as the available VM.
