You can have a look at my GitHub page [1] to get some more context. At the moment, I am in touch with Darek - core maintainer of SPDK - in order to add functionality for the virtio-vhost-user device in SPDK and DPDK. You can check some more recent activity in this thread [2]. Unfortunately, I have limited experience on Xen, but I would love to share my knowledge on this topic. Feel free to post any questions.
