# ViryaOS

## Mission

To create and support open source Xen based = tools that help users build
end-to-end secure embedded = systems.


## The Problem

Xen enables highly secure, flexible = architectures, suitable for widely
different embedded = use-cases, from industrial to IoT and cloud. However,
putting a Xen based system together is still a complex = endeavor. It is
even harder to configure it to be as = secure as possible. In the Xen
ecosystem, we lack a = unifying effort to help with the integration
challenges = that anybody building Xen-based systems is facing. Setting up
a Xen based system takes too long and it is too hard for both = users and
developers.

Today, = many of us are spending time, effort and money to maintain their
own build systems and techniques for generating VM = configurations,
resulting in significant duplication of = efforts. These scripts and tools
could be more powerful if = we worked on them together. It would cost
less to maintain = them as a shared project, and eventually, they would be
more= flexible and of better quality.


## The Solution

The solution is = to unify our efforts behind a single open source
project, = that will focus our collective development efforts on a shared
set of components.

The new = project is ViryaOS, a multi-vendor open source collaborative
effort. ViryaOS will create a highly secure easy-to-use = development
platform for Xen based systems aimed at IoT = and embedded environments.
It will make it easier for = engineers to develop secure Xen-based
platforms. In = addition, ViryaOS will produce ready-to-use binary images
to= help users and system integrators get started with Xen
on = embedded systems.

ViryaOS will provide the = space for us and others to collaborate. As a
unified = group, it will be easier to approach hardware vendors and
partners to discuss support for ViryaOS.

Users will be able to build and deploy Xen-based = disaggregated
architectures quickly and easily on x86 and = ARM SoCs. ViryaOS will support
as many hardware platforms = as possible, as many guest operating systems
as possible = (including RTOSes and proprietary OSes), and highly
heterogeneous environments. ViryaOS will meet low power = consumption
requirements.

ViryaOS will be secure out of the box. Unlike traditional = operating
system designs based on a monolithic kernel, = ViryaOS takes a microkernel
approach. ViryaOS will come = with driver and service domains. The
security and = manageability of the platform are achieved through security
by compartmentalization and privilege separation to minimize = the attack
surface of the "supervisor" component (the part = of the system capable of
unconstrained access to the = underlying hardware).

All workloads will be = supported. Virtual machines, containers, baremetal
applications and unikernels will all be first-class = "applications"
running on ViryaOS. ViryaOS will support = running containers natively and
securely by transparently = spawning Xen virtual machines for isolation.


## Build and Output

ViryaOS will come with the tools to build Xen, Dom0, multiple = VMs (with
or without device assignement) and assemble the = complete system. The
build will rely on containers to = shorten the build time and to make it
easier to reuse any = single component. The output will include the
following = binaries:

* Xen
* the Dom0 = kernel (Linux)
* the Dom0 filesystem
* a = disaggregated set of Service Domains, including their kernels,
 disk images and configurations (Service Domains = include drivers
 domains and management VMs)
* any number of user-provided containers and VMs

The result will be a ready-to-use system image = with all the pieces
already included. The image will be = small, suitable for embedded systems
and IoT.

Users will be able to select different = components and configurations at
build time, resulting in = different outputs. Cross-compilation will be
supported.

ViryaOS will be able to use Yocto and/or = existing distros such as Alpine
Linux to build some, or = all, of its components. Anything could be used
as long as = it can be built inside a container and the output follows a
specified format.

As the key = enabler for Service Domains, device assignment will be
supported on both ARM and x86 to the best of the capabilities = of the
hardware. The image will contain all the necessary = configurations
(device tree manipulations, Xen command = line arguments, etc) to make
device assignment work out of = the box.


## Security

Security is one of ViryaOS's key attributes. = The hardware capabilities
can differ for different boards, = with some having TPM support and other
TEE (trusted = execution environment) support. When the hardware supports
it, ViryaOS will use secure/measured boot on Intel and ARM, = using the
best technologies available in hardware (such as = Intel TXT and ARM
TrustZone).


## Hardware Support

ViryaOS will support as many hardware platforms as possible, = x86 and ARM
(ARMv8). Given that TPM and VT-d are (almost) = ubiquitous on Intel
platform, they can be requirements for = ViryaOS. On the ARM side, many
SoCs don't have equivalent = functionalities yet (SMMU and TEE). ViryaOS
will support = running on them, although with limited functionalities.

### x86 Requirements
* Intel VT-x or AMD-V
* 1G RAM
* Intel VT-d or AMD-Vi
* = Intel TPM
* 1 serial port for development

### ARM Requirements
#### Hard Requirements
* ARMv8 (Xen 64-bit)
* 1G RAM or better
* 1 network interface

#### Soft = Requirements
* SMMU and a Xen driver, for device = assignment (today only ARM
 SMMUv1 and SMMUv2 are = supported in Xen)
* TPM-like functionalities for secure = key storage and secure boot
* 1 serial port for = development
* Device Tree for firmware tables


## Open Source

ViryaOS is a multi-vendor collaborative open source project. = ViryaOS
will consume other upstream projects, such as the = Linux kernel, Xen
Project, Alpine Linux, and Yocto. For = convenience, ViryaOS might use
private clones of these = repositories, but ViryaOS will not diverge from
upstream = in any meaningful way. Changes to ViryaOS's private clones of
upstream repositories will only be temporary, small-scoped = and
inconsequential.  ViryaOS will remain as close as = possible to upstream
Xen and Linux.


## Certifications

For many ViryaOS use-cases safety certifications are = critical. As an
open source project, ViryaOS will attempt = at producing an easily
certifiable software stack.


## License

A permissive license is the best fit for this project. Apache = 2.0 is the
option of choice because of the clause covering = patents.

However, > putting a Xen based system together is still a complex endeavor. It is > even harder to configure it to be as secure as possible. In the Xen > ecosystem, we lack a unifying effort to help with the integration > challenges that anybody building Xen-based systems is facing. Setting up > a Xen based system takes too long and it is too hard for both users and > developers. > > Today, many of us are spending time, effort and money to maintain their > own build systems and techniques for generating VM configurations, > resulting in significant duplication of efforts.

As a > unified group, it will be easier to approach hardware vendors and > partners to discuss support for ViryaOS. > > Users will be able to build and deploy Xen-based disaggregated > architectures quickly and easily on x86 and ARM SoCs. ViryaOS will support > as many hardware platforms as possible, as many guest operating systems > as possible (including RTOSes and proprietary OSes), and highly > heterogeneous environments. ViryaOS will meet low power consumption > requirements. > > ViryaOS will be secure out of the box. Unlike traditional operating > system designs based on a monolithic kernel, ViryaOS takes a microkernel > approach. ViryaOS will come with driver and service domains. The > security and manageability of the platform are achieved through security > by compartmentalization and privilege separation to minimize the attack > surface of the "supervisor" component (the part of the system capable of > unconstrained access to the underlying hardware). > > All workloads will be supported.
