Abstract: Techniques for providing adaptive virtual function (VF) drivers capable of operating with physical devices having a plurality of different hardware configurations are described. In one embodiment, for example, an apparatus may include logic to implement a virtual machine (VM), the logic to initialize an adaptive virtual function (VF) driver to facilitate communication between the VM and a physical device to be virtualized, establish communication between the adaptive VF driver and a physical function (PF) driver of the hypervisor for the physical device, activate a standard feature set for the adaptive VF driver to execute on a PF of the physical device, and negotiate activation of an advanced feature set for the adaptive VF driver to execute on the PF, the adaptive VF driver to provide the advanced feature set to the PF, the PF activate each feature of the advanced feature set supported by the PF.
