Is that something that > runs inside the guest? Hi Wei, The user mode driver runs inside the guest. This driver is written by hardware vendors. For example, the NVIDIA's Cuda runtime is considered a user mode driver. The driver provides a specific API to applications (like the Cuda API). The cover letter explains the design of the virtual compute device paravirtualization model and describes all components, which are involved. I feel that I do not need to include explanation to every patch. Thanks Iouri
