Abstract
Embodiments of the present invention comprise methods and systems for augmenting machine virtualization by entirely bypassing resource emulation for performance-critical features, such as 3D graphics acceleration, through the use of high-performance interfaces between the guest OS and the host OS. Embodiments of the present invention also comprise methods and systems for ameliorating the performance penalties and functionality restrictions of conventional resource emulation.
Claims13
A system, comprising:
- an intercept module that intercepts a function call from an application on a guest operating system, the guest operating system in a virtual machine monitor on a host operating system;
- and
- a forwarding module that forwards the intercepted function call to the host operating system.
Dependencies are inferred from the claim text.
