[]{#anchor-48}Beyond the first production-ready release

Here are some features that may be added later :

  • App store

    • An application store for distributing prepackaged and easy-to-deploy operating systems

  • A new GUI application to manage virtual machines

    • The virtual machine manager does more than what Phyllome OS needs. It would make sense to rely on a leaner, more simple software, similar to GNOME Boxes.
    • Ideally, it would be written in Rust, just as the Cloud Hypervisor

  • Graphics

    • Out-of-the box support for Single GPU passthrough

      • Support for single GPU passthrough would make it easier to run Phyllome OS on hardware that features a single graphics card lacking support for vfio-mdev.

    • Out-of-the box support for vfio-mdev on Nvidia, consumer grade GPUs.

      • A 2021 project[^53] is bringing vfio-mdev to Nvidia, consumer grade GPUs. It would be great to support it and offer Phyllome's users the ability to split their physical GPUs.

    • Out-of-the box support for SR/IOV on generation 11^th^ of Intel graphics

  • Streaming

    • Making encoding and decoding a virtual machine desktop or display more efficient would allow for more diverse uses, including usable remote desktops.

      • For that to happen, it would mean to support virtio-video.
      • Another route would be to use WebRTC on Wayland.

  • Support the Virtual I/O Device (VIRTIO) Version 1.2

    • Version 1.2 of the VIRTIO specification will soon be released with new virtual devices. Phyllome OS will need to support these.

  • Support platform-dependent confidential computing features

    • On public clouds -- where many virtual machines are collocated underneath the same hypervisor -- there are ongoing efforts to make it possible to run workloads without having to blindly trust the host system. Some of those efforts rely on platform-specific technologies, such as Intel's SGX Secure Enclave or and AMD's Secure Encrypted Virtualization (SEV). It would be nice to be able to support these.

  • First-class support for more open x86 hardware

    • It would be great to optimize Phyllome OS to work on a recent, more open x86 motherboard that supports both openBMC and Coreboot[^54].

  • Support beyond the x86 architecture

    • Support for hardware based on ARM and RISC-V architectures would be great.
