Method and device for providing access to physical resources in a virtual machine environment |
摘要 |
<p>Techniques for providing access to physical resources in a virtual machine environment are provided. A virtual machine may access physical resources using device drivers that have been divided. After monitoring a performance of device drivers operating in a virtual machine, the device drivers that are underperforming or that experience a high rate of context switches are identified. These device drivers are adapted dynamically into portions that execute in an untrusted domain and in a trusted domain. Running a portion of the device driver in the trusted domain eliminates context switches and improves performance of the virtual machine.</p> |
