Description
The Secure VM Service Module (SVSM) for Confidential VMs can expose multiple services and virtual devices to the Linux guest. To manage these, we need a proper bus in the kernel for discovery and enumeration.
So, what is the right architectural choice for this bus? Should we write a new, minimalist bus from scratch? Or should we adapt the standardized VIRTIO framework for its broad ecosystem support? Is a hybrid approach possible, giving us the best of both worlds? This talk will explore these questions, aiming to discuss the trade-offs of each path.
