paravirtualization

Paravirtualization is a virtualization technique where the guest operating system is modified to cooperate with the hypervisor for improved performance, rather than relying on full hardware emulation. On WindowsForum.com, discussions about paravirtualization often center on Microsoft's implementation in the Windows Subsystem for Linux (WSL), particularly the DXGKRNL driver for GPU acceleration. This approach allows Linux workloads within WSL to access the GPU without conventional emulation, balancing host control and performance. However, the tension between Microsoft's WSL-first goals and the Linux kernel community's preference for maintainable, upstream-friendly design is a recurring theme. The code has undergone significant changes over several years to address these concerns.
