-## Introduction
+
+{{<section md="true" class="content-markdown">}}
+### Introduction
We want to see people contributing to the Xen Project effort, and there are many ways to do so.
Our goal is to maintain an environment of professionalism, respect, and innovation within Xen Project development.
Please adhere to our [Code of Conduct](/contribute/code-of-conduct/) in the Xen Project community.
-## Contributing code
+### Contributing code
Contributions to the Xen Project are made through patches that are reviewed by the community. We do require contributors to sign contributions using the sign-off feature of the code repository, following the same approach as the Linux Kernel does (see [Developer Certificate Of Origin](http://elinux.org/Developer_Certificate_Of_Origin)).
You can also ask questions on the [xen-devel@lists.xenproject.org](mailto:xen-devel@lists.xenproject.org) mailing list or our [Matrix channels](/resources/matrix/).
-## Submitting patches to the Xen Project codebase
+### Submitting patches to the Xen Project codebase
Please first check the submission process for the Xen Sub-Project, and send an email to the proper mailing list with [PATCH] as the first word in the subject line. Each patch should perform a single function. Patches sent to the mailing lists should be broken up into several email messages of less than 100KB each, with only one patch per email.
For details about what to include in your patch, you should start with the [patch submission documentation](https://wiki.xenproject.org/wiki/Submitting_Xen_Project_Patches)).
-## Escalation
+### Escalation
If you submitted a patch to the xen-devel mailing list or bugzilla and did not receive a response within 5 business days, please send an email to xen-devel and in the first line of that email, include this phrase "Patch escalation: no response for x days".
This is one case where you should "top post" to make sure that the escalation text is read.
-## Code security scanning
+### Code security scanning
The Xen Project is registered with the ["Coverity Scan" service](https://scan.coverity.com/faq) which applies Coverity's static analyser to the Open Source projects. The tool can and does find flaws in the source code which can include security issues. Currently only the Xen Project Hypervisor (i.e. xen.git) is covered by these scans. Triaging and proposing solutions for the flaws found by Coverity is a useful way in which Community members can contribute to the Xen Project.
Members of the community may request access to the Coverity database. However, Coverity requires that you create an account and apply for Xen Project membership by searching for the Xen Project and then requesting to be added to the project. We typically will approve requests within a few days, but reserve rejecting requests from accounts who never engaged with the project (aka never posted to a mailing list) or which look like spam accounts.

The Xen Project Advisory Board is composed of experienced members who provide guidance and support to the project. Their expertise helps shape the direction and ensures the success of the Xen Project. By collaborating with the advisory board, we can address challenges and seize opportunities in the virtualization technology landscape.

The Xen Project Hypervisor is uniquely placed to support a new range of use cases, building on top of 14 years of usage within the data center. In particular, its isolation and security features, flexible virtualization mode and architecture, driver disaggregation, and ARM support (only 47K lines of code) make it a perfect fit for embedded applications.

HVMI stands for Hypervisor-based Memory Introspection. The technology leverages Virtual Machine Introspection (VMI) APIs in the Xen and KVM hypervisors. By gaining introspection of the raw memory of running guest virtual machines, HVMI can apply security logic to detect and prevent the use of common attack techniques, such as buffer overflows, heap spray, code injection, and so-on.

A research and development team at Bitdefender extended the VMI APIs by working with the Xen Project and KVM Project communities. Bitdefender initially released a commercial solution known as GravityZone Hypervisor Introspection (HVI). The core components of HVI were open-sourced in mid-2020, forming the basis of the HVMI project.

MirageOS is a library operating system that constructs unikernels for secure, high-performance, low-energy footprint applications across various hypervisor and embedded platforms. It is available as an open-source project created and maintained by the MirageOS Core Team. A unikernel can be customised based on the target architecture by picking the relevant MirageOS libraries and compiling them into a standalone operating system, strictly containing the functionality necessary for the target. This minimises the unikernel’s footprint, increasing the security of the deployed operating system.

The high-level goal of Unikraft is to be able to build unikernels targeted at specific applications without requiring the time-consuming, expert work that building such a unikernel requires today. An additional goal (or hope) of Unikraft is that all developers interested in unikernel development would contribute by supplying libraries rather than working on independent projects with different code bases as it is done now.

The main license of the run-time components of Unikraft is a 3-clause BSD license unless there is a good reason not to use it (e.g. we may import 2-clause BSD licensed code from Mini-OS, which we would not anticipate to change). The Makefile system would be licensed under GPL v2 or later as we want to be able to use KConfig functionality from Buildroot/Linux.

When used with Xen, the XAPI toolstack consolidates server workloads, enables savings in power, cooling, and management costs (contributing to environmentally sustainable computing), increases the ability to adapt to ever-changing IT environments, optimizes the use of existing hardware, and improves the level of IT reliability.
The XAPI team also develops tooling, agents and libraries that are needed to operate a XAPI-based system.

Qubes OS is a security-focused operating system based on Xen. The goal of Qubes OS is to create a reasonably secure environment that is also practical and usable, capable of playing the role of a daily driver rather than a highly situational solution - and Xen is a major reason why we can confidently say that Qubes OS succeeds.
