Abstract

A computing platform having transparent access to resources of a host platform is described herein. In one embodiment, an example of a computing system includes, but is not limited to, a virtual operating system (VOS) including a VOS kernel and a first library, a host operating system (HOS) including a HOS kernel and a second library, and a communication channel established with the VOS kernel and the HOS kernel that directly couples the first library and the second library. Other methods and apparatuses are also described.

Claims

1. A computer system, comprising:

a virtual operating system (VOS) including a VOS kernel and a first library;

a host operating system (HOS) including a HOS kernel and a second library; and

a communication channel established with the VOS kernel and the HOS kernel that directly couples the first library and the second library.

2. The system of claim 1, wherein one of the first and second libraries dispatches calls to the other of the first and second libraries.

3. The system of claim 1, wherein at least one of the first and second libraries is a cross-platform library.

4. The system of claim 1, wherein an application of the VOS uses the first library to dispatch calls to the second library to access host resources of the HOS.

5. The system of claim 1, wherein the VOS does not have a graphical user interface and an application of the VOS uses a graphical user interface of the HOS to enable the application of the VOS to have an appearance and interaction that is substantially identical to an application of the HOS.

6. The system of claim 1, wherein an application of the VOS uses the first library to dispatch calls to the second library to enable the application of the VOS to have an appearance and interaction that is substantially identical to an application of the HOS.

7. The system of claim 1, further comprising:

a compiler to dynamically translate a first executable of the VOS to a second executable of the HOS,

wherein library calls of the first executable directed to the first library are translated in the second executable to library calls directed to the second library and a subset of translated calls to the second library is dispatched back to the first library.

8. The system of claim 1, further comprising:

a compiler to dynamically translate a first executable of the VOS to a second executable of the HOS,

wherein library calls of the first executable directed to the first library are translated in the second executable to library calls directed to the second library and a subset of translated calls to the second library is dispatched back to a third library of the VOS.

9. The system of claim 1, wherein the VOS is one of a system emulator, a virtual private server, an application virtual operating system, and a hypervisor.

10. The system of claim 1, further comprising:

a first application that runs on the VOS;

a second application that runs on a second VOS including a second VOS kernel;

at least one security policy that governs both applications and that specifies interactions of the applications allowed in the HOS; and

a security framework within a library of the HOS to trap illegal calls and operations to protect the HOS according to the at least one security policy associated with the applications.

11. The system of claim 1, further comprising:

a first application that runs on the VOS;

a second application that runs on a virtual processing unit;

at least one security policy that governs both applications and that specifies interactions of the applications allowed in the HOS; and

a security framework within a library of the HOS to trap illegal calls and operations to protect the HOS according to the at least one security policy associated with the applications.

12. A method for enabling the execution of a virtual operating system application comprising:

establishing a communication channel between a virtual operating system (VOS) kernel of a VOS and a host operating system (HOS) kernel of a HOS;

coupling a first library on the VOS directly to a second library on the HOS using the communication channel; and

dispatching calls from a VOS application to the first and second libraries using the communication channel.

13. The method of claim 12, wherein the first and second library expose a single programming interface that the VOS application dispatches calls to.

14. The method of claim 13, further comprising:

dispatching a subset of calls received by the programming interface to one of the first and second library using the communication channel.

15. The method of claim 12, further comprising:

receiving a first VOS application to be run on the VOS, a second virtual machine application to be run on a virtual machine, and at least one security policy that governs both applications;

translating security policy into a form compatible with a host library of a host operating system (HOS);

channeling all calls that affect the HOS and are made by the first virtual machine application and the second virtual machine application through the host library; and

trapping operations of the host library on the HOS according to the translated security policy.

16. The method of claim 13, further comprising:

receiving a first VOS application to be run on the VOS, a second VOS application to be run on a second VOS including a second VOS kernel, and at least one security policy that governs both applications;

translating the universal security policy into a form compatible with a host library of a host operating system (HOS);

channeling all calls that affect the HOS and are made by the first VOS application and the second VOS application through the host library; and

trapping operations of the host library on the HOS according to the translated universal security policy.

17. A machine-readable medium for storing instructions, when executed by a processor, causes the processor to perform operations, the operations comprising:

establishing a communication channel between a virtual operating system (VOS) kernel of a VOS and a host operating system (HOS) kernel of a HOS;

coupling a first library on the VOS directly to a second library on the HOS using the communication channel; and

dispatching calls from a VOS application to the first and second libraries using the communication channel.
