Section under construction. Tables is broken. Would have to fix it. {.is-warning}
Take this table as an example:
| Description | vfio-pci | vfio-mdev | vfio-gpu |
|---|---|---|---|
| Performance | Near-native performance and full features set | Near-native performance and full features set | Degraded performance and limited features set |
| Guests support | UNIX and non-UNIX guests | UNIX and non-UNIX guests | Works only on selected UNIX guests |
| Driver | No special driver in the guest | No special driver in the guest | Requires a special driver in the guest |
| Number of host GPUs | Two GPUs in most situations | A single GPU | A single GPU |
| GPU support | Mostly GPU agnostic | Recent Intel integrated GPUs and some professional grade Nvidia GPUs | Mostly GPU agnostic |

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
- Out-of-the box support for Single GPU passthrough
- 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.
- Making encoding and decoding a virtual machine desktop or display more efficient would allow for more diverse uses, including usable remote desktops.
- 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.
