Abstract

Methods, systems, and devices are described for providing distributed virtual desktops. In these methods, systems, and devices, a first user is authenticated at a first machine communicatively coupled with a server computer system. A second machine communicatively coupled with the server computer system is selected to host an operating system session associated with the first user. Input/output functionality for the operating system session associated with the first user is assigned to the first machine, and the first machine is instructed to communicate with the second machine such that the input/output functionality provided by the first machine is mapped to the operating system session associated with the first user at the second machine.

Claims

1. A system for providing distributed virtual desktops, the system comprising:

a plurality of machines, each machine being configured to host at least one operating system session and provide an input/output functionality; and

a server computer system communicatively coupled with each of the machines, wherein the server computer system is configured to;

authenticate a first user at a first machine of the plurality of machines;

select a second machine of the plurality of machines to host an operating system session associated with the first user;

assign the first machine to provide input/output functionality for the operating system session associated with the first user; and

instruct the first machine to communicate with the second machine such that the input/output functionality provided by the first machine is mapped to the operating system session associated with the first user at the second machine.

2. The system of claim 1, wherein the server computer system is further configured to:

determine that the first user has logged out of the operating system session;

allow the second machine to continue running the operating system session;

authenticate the first user at a third machine; and

instruct the third machine to communicate with the second machine such that the input/output functionality provided by the third machine is mapped to the operating system session of the second machine.

3. The system of claim 1, wherein the server computer system is further configured to:

select the first machine to host a second operating system session associated with a second user; and

assign a fourth machine to provide input/output functionality for the second operating system session at the first machine.

4. The system of claim 3, wherein the server computer system is further configured to:

instruct the first machine to communicate with the fourth machine to implement input/output functionality for the second operating system session at the fourth machine.

5. The system of claim 1, wherein the server computer system is further configured to:

identify the first user prior to mapping the input/output functionality provided by the first machine to the operating system session associated with the first user at the second machine;

wherein the authenticating the first user at the first machine occurs after the mapping the input/output functionality provided by the first machine to the operating system associated with the first user at the second machine.

6. A method of providing a distributed virtual desktop, the method comprising:

authenticating a first user at a first machine communicatively coupled with a server computer system;

selecting a second machine communicatively coupled with the server computer system to host an operating system session associated with the first user;

assigning input/output functionality for the operating system session associated with the first user to the first machine; and

instructing the first machine to communicate with the second machine such that the input/output functionality provided by the first machine is mapped to the operating system session associated with the first user at the second machine.

7. The method of claim 6, further comprising:

identifying the first user prior to mapping the input/output functionality provided by the first machine to the operating system session associated with the first user at the second machine;

wherein the authenticating the first user at the first machine occurs after the mapping the input/output functionality provided by the first machine to the operating system associated with the first user at the second machine.

8. The method of claim 6, further comprising:

determining that the first user has logged out of the operating system session; and

removing a mapping between the input/output functionality of the first machine and the operating system session of the second machine.

9. The method of claim 8, further comprising:

allowing the second machine to continue running the operating system session.

10. The method of claim 8, further comprising:

authenticating the first user at a third machine; and

instructing the third machine to communicate with the second machine such that the input/output functionality provided by the third machine is mapped to the operating system session of the second machine.

11. The method of claim 6, further comprising:

selecting the first machine to host a second operating system session associated with a second user; and

assigning a fourth machine to provide input/output functionality for the second operating system session at the first machine.

12. The method of claim 11, further comprising:

instructing the first machine to communicate with the fourth machine to implement input/output functionality for the second operating system session at the fourth machine.

13. The method of claim 6, wherein the selecting the second machine to host the operating system session associated with the first user comprises:

determining that the operating system session is already in existence and hosted at the second machine; and

allowing the second machine to continue hosting the operating system session associated with the first user.

14. The method of claim 6, further comprising:

instructing the second machine to instantiate the operating system session associated with the first user.

15. The method of claim 6, further comprising:

maintaining a record at a data store of the selection of the second machine to host the operating system session associated with the first user and the assignment of the first machine to provide input/output functionality for the operating system session at the second machine.

16. A method of providing distributed virtual desktops, the method comprising:

receiving login credentials from a first user at a first machine;

communicating with a server computer system to authenticate the user based on the login credentials;

receiving a selection by the server computer system of a second machine to host an operating system session associated with the first user; and

communicating with the second machine to map input/output functionality provided at the first machine to the operating system session associated with the first user at the second machine.

17. The method of claim 16, further comprising:

hosting an operating system session associated with a second user at the first machine while the input/output functionality of the first machine is mapped to the operating system session associated with the first user at the second machine.

18. The method of claim 17, further comprising:

communicating with a third machine to map input/output functionality of the third machine to the operating system session associated with the second user.

19. The method of claim 18, further comprising:

receiving notification that the second user has logged off of the third machine; and

removing the mapping between the input/output functionality of the third machine and the operating system session associated with the second user.

20. The method of claim 19, further comprising:

continuing to run the operating system session associated with the second user after removing the mapping between the input/output functionality of the third machine and the operating system session associated with the second user.

21. The method of claim 17, further comprising:

allowing the first user to log off of the first machine;

notifying the server computer system that the first user has logged off of the first machine; and

removing the mapping between the input/output functionality of the first machine and the operating system session associated with the first user.

22. The method of claim 17, wherein the input/output functionality of the first machine comprises keyboard video mouse (KVM) functionality.
