Hi,
Following up on my earlier email; it seems that a BSP layer targeting the Firecracker VM model could/should pay some dividends.

Recapping the Firecracker 'board' model is: "only 5 emulated devices are available: virtio-net, virtio-block, virtio-vsock, serial console, and a minimal keyboard controller used only to stop the microVM"

Does any one know of a conceptually similar BSP layer, or any other that could serve as a launch point?

Kind regards
Mark
