# Prepare the host computer
|
||||
|
||||
## Requirements
|
||||
|
||||
These instructions are valid for x86-64 computers that do ship with Linux or Windows.
|
||||
|
||||
Phyllome OS targets x86 systems with hardware-assisted virtualization, with a strong preference for those providing IOMMU as well.
|
||||
|
||||
It is expected that Phyllome OS will consume approximately 1 CPU core and 1 GB of RAM, which should be enough to accommodate a few
|
||||
virtual machines. For instance, on a system with a CPU with 4 cores and 8 GB of RAM, a guest virtual machine will be able to be assigned up to 3 cores and 7 GB of RAM.
|
||||
|
||||
### Minimum requirements for Phyllome OS Desktop
|
||||
|
||||
* x86 computer that supports the first generation of hardware-assisted virtualization extensions
|
||||
* For AMD-based configurations, it means that AMD V is available and enabled
|
||||
* For Intel-based configurations, it means that Intel VT-x is available and enabled
|
||||
* 2-core processor
|
||||
* 8 GB of RAM
|
||||
* SSD-based storage device to store disk images and Phyllome OS
|
||||
* Any graphics card (Linux or macOS guests only)
|
||||
|
||||
### Recommended requirements for Phyllome OS Desktop
|
||||
|
||||
* x86 computer that supports the second generation of hardware-assisted virtualization extensions
|
||||
* For AMD-based configurations, it means that AMD Vi is available and enabled
|
||||
* For Intel-based configurations, it means that Intel VT-d is available and enabled
|
||||
* 8-core processor
|
||||
* 16 GB of RAM
|
||||
* NVME-based storage device to store disk images and Phyllome OS
|
||||
* Two graphics cards or a graphics card that supports vfio-mdev or SR-IOV
|
||||
|
||||
## Enable IOMMU
|
||||
|
||||
### Access the firmware
|
||||
|
||||
During the boot process, you need to press a certain key to access the firmware configuration tool for your motherboard, also known as BIOS or UEFI.
|
||||
|
||||
The most common keystrokes are <kbd>F2</kbd> or <kbd>Del</kbd>.
|
||||
|
||||
Hardware manufacturers could not agree on a common keystroke to access the firmware configuration tool, so please have a look at the documentation provided by your hardware manufacturer.
|
||||
|
||||
* **Windows-based computers**
|
||||
|
||||
`to be done`
|
||||
|
||||
### Modify the firmware configuration
|
||||
|
||||

|
||||
|
||||
### Make sure that hardware-assisted virtualization is enabled

### Phyllome OS
|
||||
|
||||
Phyllome OS intends to tap into some modern software- and
|
||||
hardware-related innovations used in the cloud and make them available
|
||||
to a wider audience locally: to bring some of the cloud back home, so to
|
||||
speak, with a focus on performance and usability. As an operating
|
||||
system, Phyllome OS makes it easier to run virtual machines locally
|
||||
using off-the-shelf hardware : it is designed from the ground up to be
|
||||
easy[^27]-and safe[^28]-to-use.

|
||||
|
||||
Conceptually, Phyllome OS can be thought of in several ways : as a
|
||||
wrapper around operating systems that use a Graphical User Interface
|
||||
(GUI), just as Docker is, among other things,a headless wrapper around
|
||||
GUI-less containers ; as an abstraction between the hardware and the
|
||||
operating system; as a local-first appliance or sandbox whose sole
|
||||
purpose is to run general computing operating systems using
|
||||
hardware-assisted virtualization, and hopefully run them well ; or as
|
||||
just another attempt to bring Linux back to the desktop, albeit more
|
||||
covertly this time.

As with popular existing operating systems, Phyllome OS is designed to
|
||||
be installed on a single machine or host. Contrary to existing operating
|
||||
systems, it abstracts the physical layer away, allowing diverse
|
||||
operating systems to run concurrently on the same machine if the user so
|
||||
desires.

### Can you explain the whole project and its expected outcome(s) ?
|
||||
|
||||
Traditionally, operating systems (OS) installed directly on physical hardware have unfiltered access to the underling system hardware, which they trust by default. In contrast, when deployed inside virtual machines, this access can be mediated at the hypervisor/host level, enhancing the security of the overall system by allowing the user to distrust parts of the hardware stack, a vision that is implemented thorougly by the [QubesOS](https://www.qubes-os.org/), which Phyllome OS draws inspiration from.

- By using Phyllome OS on Apple hardware that do not support the

latest iteration of macOS, one could create a virtual machine and

install the latest iteration of macOS anyway, further extending the

life of hardware.

* **Note:** Phyllome OS does not and will **not** support running macOS on anything but Apple hardware, as it is -- sadly -- not allowed by Apple.

words, when a user acquires a new physical computer, the entire computing environment may be copy/pasted to the new machine.
|

- **Compatibility** : contrary to silicon-based computers, which tend to be optimized to work at most with only a handful operating
|
||||
systems, a virtual machine can be designed to work with most operating systems.

### Limitations
|

|

Alas, it also comes with limitations, including but not limited to :
|
||||
|
||||
- Limited out-of-the box hardware support : hardware-assisted
|
||||
virtualization is available on many computers but rarely activated
|
||||
by default and not always correctly implemented. Users remain a the
|
||||
mercy of good platform firmware and may have to explicitly activate
|
||||
hardware-assisted virtualization in the BIOS/UEFI. Hardware
|
||||
components are often not correctly isolated in IOMMU groups.

|
||||
* Offering first-class support for only a handful of curated computers might provide an answer, at the price of compatibility.
|
||||
* When it comes to IOMMU groups, a workaround might have to be used for models that do not offer well-isolated IOMMU groups, a workaround that has security implications.

have, including out of the box support for Bluetooth, wireless, or

|
||||
GPUs.

- Making encoding and decoding a virtual machine desktop or
