Unifying KVM API for Protected Virtual Machines and Utilities

Explore the challenges and opportunities in unifying the KVM API for protected virtual machines and related utilities. Delve into the current landscape where different technologies for protected guests employ varied APIs for guest construction and debugging. Examine the potential for standardization across user space VMMs like QEMU and Cloud Hypervisor, as well as related components such as VFIO. Discuss which APIs can be unified and which may require vendor-specific implementations. Consider strategies to streamline KVM integration for user space VMMs and associated components, making it easier to support protected guests while balancing the need for flexibility and specialization.
