Yes, this is why I did say "apart from the windows idea". > And it is also a > centralized approach where all message go through the main Linux > instance. I suspect we could cover that use case as well with generic > inter-vm shared memory device, but I didn't think about all details yet. The virtqueue handling seems very similar between the two. However, the messages for rpmsg however have a small header (struct rpmsg_hdr in include/linux/rpmsg.h) and there is a weird feature bit VIRTIO_RPMSG_F_NS. So I guess virtio-rpmsg and virtio-peer are about as similar as virtio-serial and virtio-peer.
