### 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 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.
