Graphics Virtualization Date of insert: July 11 2017; Verified: Not updated in 2020; GSoC: Unknown Technical contact: (OpenXT) Rich Persaud, Christopher Clark Mailing list/forum for project: xen-devel@ IRC channel for project: #xen-devel Difficulty: Unknown Skills Needed: Unknown Description: GPU virtualization is used in Server VDI, Automotive, Desktops and Laptops. GPU vendors have different approaches to virtualization of 3D graphics (NVIDIA GRID, AMD MxGPU, Intel GVT, Imagination PowerVR OmniShield), while software-based graphics virtualization may not support modern video and user interface animations. Gaming is one of the few growth areas for PCs and CAD can be done via remote desktop. What are current best practices for Xen users and developers to achieve high-performance 3D graphics on Windows, Linux and Android? Is KVM better than Xen for graphics virtualization? Intel GVT-d and GVT-G with local multi-monitor display Zero-copy display of guest framebuffers: Intel GVT, ARM with and without IOMMU Baboval 2013: http://events.linuxfoundation.org/sites/events/files/slides/Zero-Copy%20Display%20of%20Guest%20Framebuffers%20using%20GEM.pdf Display management: GVT, PV-displ, Qubes compositor, OpenXT surfman HID virtualization (secure input, seamless mouse-display switching, multi-touch) SCHEDULE: http://sched.co/AjEV Outcomes: Not specified, project outcomes Peer Review Comments   Feel free to make suggestions here  And whether you intend to attend:

Xen Toolstacks for Server and Edge Use Cases Date of insert: July 11 2017; Verified: Not updated in 2020; GSoC: Unknown Technical contact: (OpenXT) Rich Persaud, Christopher Clark, Chris Rogers Mailing list/forum for project: xen-devel@ IRC channel for project: #xen-devel Difficulty: Unknown Skills Needed: Unknown Description: Many Xen toolstacks have come and gone. Libxenlight was created to provide a common base layer upon which higher-level toolstacks could be built. What is the roadmap for libxenlight to meet the needs of servers, local/enterprise managed clients, OTA update for embedded and mobile devices, unikernels, containers and automated testing? Can we reduce duplication among libvirt, xapi (Ocaml), xenrt (Python) and OpenXT (Haskell) toolstacks? Can Xen management tools compete with DevOps expectations set by the fast-moving container ecosystem? LibXL configurable build (equivalent to hypervisor Kconfig) error handling: map error messages to numeric codes Configuration file for stub domains: Mini-OS, Linux (GPU/NIC PT, CD), rumpkernel State management: multiple LibXL clients per host CoreOS rkt and Xen Toolstack Service VMs Xenstore isolation: options between 1/host and 1/VM?

Testing Server and Edge Hypervisors Date of insert: July 11 2017; Verified: Not updated in 2020; GSoC: Unknown Technical contact: (OpenXT) Rich Persaud, Christopher Clark Mailing list/forum for project: xen-devel@ IRC channel for project: #xen-devel Difficulty: Unknown Skills Needed: Unknown Description: Virtualization increasingly depends on hardware support, while hardware diversity continues to increase. At present, common feature configurations are tested and given first-class support. Other configurations imply expert mode and private testing. Derivative projects also carry patches that may not be acceptable to upstream Xen, but are common to edge (client, embedded) use cases. Can downstream projects contribute test capacity for non-server configurations of Xen? These test cases are relevant to OpenXT: Xen feature subsets (Kconfig) GPU passthrough/virtualization with local display: Linux, Windows (USB video capture) Measured Launch (Intel TXT, AMD SVM, TPM 1.2, TPM 2.0) Inter-VM communication: libvchan, V4V Stub domains: Mini-OS, Linux Driver domains: network, USB SCHEDULE: http://sched.co/AjGk Outcomes: Not specified, project outcomes Peer Review Comments   Feel free to make suggestions here  And whether you intend to attend:
