Abstract

A client hosted virtualization system includes a task oriented device, a processor, and non-volatile memory with BIOS code and virtualization manager code. The virtualization manager initializes the client hosted virtualization system, authenticates a virtual machine image, launches the virtual machine based on the image, receives a transaction targeted to the task oriented device, prioritizes the transaction, sends the transaction to the task oriented device, receives a response from the task oriented device, and sends the response to the virtual machine. The client hosted virtualization system is configurable to execute the BIOS or the virtualization manager.

Claims (104)

1. A client hosted virtualization system (CHVS) comprising:

a task oriented device;

a processor operable to execute code; and

a non-volatile memory including first code to implement a basic input/output system to initialize the CHVS, and second code to implement a virtualization manager operable to:

initialize the CHVS;

authenticate a first virtual machine image associated with a first virtual machine;

launch the first virtual machine on the CHVS based on the first virtual machine image;

receive a first transaction from the first virtual machine, a target of the first transaction being the task oriented device;

prioritize the first transaction;

send the first transaction to the task oriented device; and

receive a first response to the first transaction from the task oriented device; and

send the first response to the first virtual machine;

wherein the processor is operable to:

determine if the first code is selected;

execute the first code in response to determining that the first code is selected; and

execute the second code in response to determining that the first code is not selected.

2. The CHVS of claim 1 , further comprising a mass storage device, and wherein the first virtual machine image:

is stored on the mass storage device; and

includes an operating system and an application.

3. The CHVS of claim 1 , wherein the virtualization manager is further operable to prioritize the first transaction into a first queue associated with the first virtual machine.

4. The CHVS of claim 1 , wherein the task oriented device includes a general purpose encryption engine, and the first transaction includes a public key infrastructure key.

5. The CHVS of claim 1 , wherein the task oriented device includes a deep packet inspection engine.

6. The CHVS of claim 3 , wherein the virtualization manager is further operable to:

authenticate a second virtual machine image associated with a second virtual machine;

launch the second virtual machine on the CHVS based on the second virtual machine image;

receive a second transaction from the second virtual machine, a target of the second transaction being the task oriented device;

prioritize the second transaction;

send the second transaction to the task oriented device;

receive a second response to the second transaction from the task oriented device; and

send the second response to the second virtual machine.

7. The CHVS of claim 6 , wherein the virtualization manager is further operable to:

prioritize the second transaction into a second queue associated with the second virtual machine;

determine that the first transaction has a higher priority than the second transaction; and

send the first transaction to the task oriented device before sending the second transaction to the task oriented device.

8. The CHVS of claim 7 , wherein the virtualization manager is further operable to:

assign a first task identifier to the first transaction; and

determine that the first response includes the first task identifier;

wherein sending the first response to the first virtual machine is in response to determining that the first response includes the first task identifier.

9. A method of providing a client hosted virtualization system (CHVS) comprising:

storing first code in a non-volatile memory of the CHVS to implement a basic input/output system to initialize the CHVS;

storing second code in the non-volatile memory, the second code being operable to:

initialize the CHVS;

authenticate a first virtual machine image associated with a first virtual machine;

launch the first virtual machine on the CHVS based on the first virtual machine image;

receive a first transaction from the first virtual machine, a target of the first transaction being a task oriented device of the CHVS;

prioritize the first transaction;

send the first transaction to the task oriented device;

receive a first response to the first transaction from the task oriented device; and

send the first response to the first virtual machine;

determining if the first code is selected;

in response to determining that the first code is selected, executing the first code; and

in response to determining that the first code is not selected, executing the second code.

10. The method of claim 9 , wherein the first virtual machine image includes an operating system and an application.

11. The method of claim 9 , wherein in prioritizing the first transaction, the second code is further operable to place the first transaction into a first queue associated with the first virtual machine.

12. The method of claim 9 , wherein the task oriented device includes a general purpose encryption engine, and the first transaction includes a public key infrastructure key.

13. The method of claim 9 , wherein the task oriented device includes a deep packet inspection engine.

14. The method of claim 11 , the second code being further operable to:

authenticate a second virtual machine image associated with a second virtual machine;

launch the second virtual machine on the CHVS based on the second virtual machine image;

receive a second transaction from the second virtual machine, a target of the second transaction being the task oriented device;
