I would love to get started with the project. I have a small update as well. I have read through a few docs and articles to familiarize myself with the relevant terminology and technicalities. 1. "About", "system emulation" and "user mode emulation" sections of the user documentation [1] 2. The migration subsystem [2] Some sections in the above docs were difficult to grasp. For the time being, I have focused on those parts that I thought were relevant to the project. I have also read through the following articles: 1. Introduction to virtio-networking and vhost-net [3] 2. Deep dive into Virtio-networking and vhost-net [4] 3. Virtualized Hardware Devices [5] 4. VFIO - "Virtual Function I/O" (Just the introduction) [6] 5. Virtio-net failover: An introduction [7] I hope I haven't gone off on a tangent. I was planning to finish reading up on the following articles as well: 1. Virtqueues and virtio ring: How the data travels [8] 2. Packed virtqueue: How to reduce overhead with virtio [9] 3. Virtio live migration technical deep dive [10] 4. Hands on vDPA: what do you do when you ain't got the hardware v2 (Part 1) [11] I believe the hands-on vPDA article will have me set up a development environment for the project as well. Please let me know if I should amend my roadmap. I am excited to get started :) Thanks, Sahil [1] https://www.qemu.org/docs/master/index.html [2] https://www.qemu.org/docs/master/devel/migration/index.html [3] https://www.redhat.com/en/blog/introduction-virtio-networking-and-vhost-net [4] https://www.redhat.com/en/blog/deep-dive-virtio-networking-and-vhost-net [5] https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/virtualization_getting_started_guide/sec-virtualization_getting_started-products-virtualized-hardware-devices [6] https://www.kernel.org/doc/html/latest/driver-api/vfio.html [7] https://www.redhat.com/en/blog/virtio-net-failover-introduction [8] https://www.redhat.com/en/blog/virtqueues-and-virtio-ring-how-data-travels [9] https://developers.redhat.com/articles/2024/02/21/virtio-live-migration-technical-deep-dive [10] https://www.redhat.com/en/blog/packed-virtqueue-how-reduce-overhead-virtio [11] https://www.redhat.com/en/blog/hands-vdpa-what-do-you-do-when-you-aint-got-hardware-part-1
