Summary:PURPOSE: Hypervisor driver management in a VM environment is provided to execute a part of a device driver in a trust domain, thereby eliminating context switching and improving the performance of a VM. CONSTITUTION: A VM(Virtual Machine) is driven in a VM environment. The VM environment comprises a trust domain and a driver domain. The performance of device drivers operating in the VM is monitored(402). The device driver operating under a threshold is discriminated according to the performance characteristic of the device driver(404). The device driver is adapted to the first and the second part(406). The first part is executed in the trust domain. The second part is executed in the driver domain(408).
