Hi, some super high level questions: > different controllers according to their needs. A backend > example can be found in the device model of the open source > project ACRN. For more information, please refer to > https://projectacrn.org. Could you provide a link directly to the backend, please? > The device ID request: > https://github.com/oasis-tcs/virtio-spec/issues/85 Shall we wait for this to be approved?

The hardware can be emulated by any device model > + software according to the virtio protocol. That means stuff like "limiting which devices on a given bus can be accessed" will be handled by the backends, or? What kind of testing has been done with this on which setup? Thanks and happy hacking, Wolfram
