Hi, I'm working on a VirtIO / vhost audio virtualisation solution [1,2] and although it's already working rather well, some points still need clarification. 1. Guest identification. Is there a standard way to identify guests in a vhost driver? We need to send different audio topology to different guests, therefore we need a way to reliably identify them. 2. Runtime PM. Is there a standard or a preferred way to implement runtime PM on the host side to guarantee that the device is always powered on when guests need it and can be runtime suspended otherwise?
