Over the past several years we have seen the continued adoption of OpenStack and it’s expansion into new areas: from cloud service providers, enterprise private clouds to large media companies, telecommunication giants, and big science. At the same time, open source based platforms for network functions virtualization (NFV) are fueling a movement toward cloud computing in almost all major telco’s. In the developer world, open source projects, such as Docker, Mesos, Kubernetes, and Spark are gaining a lot of attention and being integrated into OpenStack through projects Kolla and Magnum. This session will cover how these projects and activities relate to each other and further expand the utility and adoption OpenStack.

Analogous to server virtualization, Network Virtualization decouples and isolates virtual networks (i.e. tenant) from the underlying network hardware. One of the key value propositions of Software-Defined Networking (SDN) is to enable the provisioning and operation of virtual networks. This tutorial motivates the need for network virtualization, describes the high-level requirements, provides an overview of all architectural approaches, and gives you a clear picture of the vendor landscape. Previously presented at ONUG Fall 2013 and Spring 2014.

The adoption of Cloud Computing Solutions in datacenters worldwide has proven to be the right path, as it reduces costs, automates operation tasks and improve time-to-market for newly developed applications. However, cloud solutions are still in an early stage and do not meet all requirements for company environments, especially those with high capacity With that in mind, Globo.com embraced an open cloud solutions, Cloudstack, and began developing together with the community to fulfill all its high availability, high capacity and high throughput requirements. Integration between Cloudstack and Globo.com’s infrastructure happens in all levels, with an special attention to network equipment management, DNS automation and load balancing.

Static partitioning is used to split an embedded system into multiple domains, each of them having access only to a portion of the hardware on the SoC. It is key to enable mixed-criticality scenarios, where a critical application, often based on a small RTOS, runs alongside a larger non-critical app, typically based on Linux. The two domains cannot interfere with each other. This talk will explain how to use Xen for static partitioning. It will introduce dom0-less, a new Xen feature written for the purpose. Dom0-less allows multiple VMs to start at boot time directly from the Xen hypervisor, decreasing boot times drastically. It makes it very easy to partition the system without virtualization overhead. Dom0 becomes unnecessary. This presentation will go into details on how to setup a Xen dom0-less system. It will show configuration examples and explain device assignment. The talk will discuss its implications for latency-sensitive and safety-critical environments.

TrenchBoot is a cross-community OSS integration project for hardware-rooted, late launch integrity of open and proprietary systems. It provides a general purpose, open-source DRTM kernel for measured system launch and attestation of device integrity to trust-centric access infrastructure. TrenchBoot closes the UEFI Measurement Gap and reduces the need to trust system firmware. This talk will introduce TrenchBoot architecture and a recent collaboration with Oracle to launch the Linux kernel directly with Intel TXT or AMD SVM Secure Launch. It will propose mechanisms for integrating the Xen hypervisor into a TrenchBoot system launch. DRTM-enabled capabilities for client, server and embedded platforms will be presented for consideration by the Xen community.

In recent years unikernels have shown immense performance potential (e.g., boot times of only a few ms, image sizes of only hundreds of KBs).The fundamental drawback of unikernels is that they require that applications be manually ported to the underlying minimalistic OS, needing both expert work and often considerable amount of time. The Unikraft project provides a unikernel code base and build system that significantly simplifies the building of unikernels. In addition to support for a number CPU architectures, languages and frameworks, Unikraft provides debugging and tracing features that are generally sorely missing from unikernel projects. In this talk we will talk about these features, show a set of preliminary performance numbers, and provide a roadmap for the project's future.

This talk will introduce Dom0-less: a new way of using Xen to build mixed-criticality solutions. Dom0-less is a Xen feature that adds a novel approach to static partitioning based on virtualization. It allows multiple domains to start at boot time directly from the Xen hypervisor, decreasing boot times dramatically. Xen userspace tools, such as xl and libvirt, become optional. Dom0-less extends the existing device tree based Xen boot protocol to cover information required by additional domains. Binaries, such as kernels and ramdisks, are loaded by the bootloader (u-boot) and advertised to Xen via new device tree bindings. The audience will learn how to use Dom0-less to partition the system. Uboot and device tree configuration details will be explained to enable the audience to get the most out of this feature. The talk will include a status update and details on future plans.

As the number of contributions grow, reviewer bandwidth becomes a bottleneck; and maintainers are always asking for more help. However, ultimately maintainers must at least Ack every patch that goes in; so if you're not a maintainer, how can you contribute? Why should anyone care about your opinion? This talk will try to lay out some advice and guidelines for non-maintainers, for how they can do code review in a way which will effectively reduce the load on maintainers when they do come to review a patch.

Safety certification is one of the essential requirements for software to be used in highly regulated industries. Besides technical and compliance issues (such as ISO 26262 vs IEC 611508) transitioning an existing project to become more easily safety certifiable requires significant changes to development practices within an open source project. In this session, we will lay out some challenges of making safety certification achievable in open source and the Xen Project. We will outline the process the Xen Project has followed thus far and highlight lessons learned along the way. The talk will primarily focus on necessary process, tooling changes and community challenges that can prevent progress. We will be offering an in-depth review of how Xen Project is approaching this challenging goal and try to derive lessons for other projects and contributors.

2018 saw fundamental shifts in security boundaries which were previously taken for granted. A lot of work has been done in the past 2 years, and largely in secret under embargo, but there is plenty more work to be done to strengthen the existing mitigations and to try to recover some performance without reopening security holes. This talk will look at speculative execution sidechannels, the work which has already been done to mitigate the security holes, and future work which hopes to bring some improvements.

The Arm architecture provides a set of guidelines that any software should abide by when accessing the memory with MMU off and update page-tables. Failing to do so may result in getting TLB conflicts or breaking coherency. In a previous talk ("Keeping coherency on Arm"), we focused on updating safely the stage-2 (aka P2M) page-tables. This talk will focus on the boot code and Xen memory management. During this session, we will introduce some of the guidelines and when they should be used. We will also discuss how Xen boot sequence needs to be reworked to avoid breaking the guidelines.

For many years the QEMU codebase has contained PV backends for Xen guests, giving them paravirtual access to storage, network, keyboard, mouse, etc. however these backends have not been configurable as QEMU devices as their implementation did not fully adhere to the QEMU Object Model (QOM). Particularly the PV storage backend not using proper QOM devices, or qdevs, meant that the QEMU block layer needed to maintain legacy code that was cluttering up the source. This was causing push-back from the maintainers who did not want to accept any patches relating to that Xen backend until it was 'qdevified'. In this talk, I'll explain the modifications I made to QEMU to achieve 'qdevification' of the PV storage backend, how compatibility with the libxl toolstack was maintained, and what the next steps in both QEMU and libxl development should be.

PCI is a local computer bus for attaching hardware devices in a computer, and is the main peripheral bus on modern x86 systems. As such, having a proper way to emulate it is crucial for Xen to be able to expose both fully emulated devices or passthrough devices to guests. This talk will focus on the current status of PCI emulation in Xen, how and where it is used, what are its main limitations and future plans to improve it in order to be more robust and modular.

Xen is a very powerful hypervisor with a talented and diverse developers community. Despite the fact it's almost everywhere (from the Cloud to the embedded world), it can be difficult to set up and manage as a system administrator. General purpose distros have Xen packages, but that's just a start in your Xen journey: you need some tooling and knowledge to have a working and scalable platform. XCP-ng was built to overcome those issues: by bringing Xen to the masses with a fully turnkey distro with Xen as its core. It's the logical sequel to the XCP project, with a community focus from the start. We'll see how it happened, what we did, and what's next. Finally, we'll see the impact of XCP-ng on the Xen Project.

High level toolstacks for server and cloud virtualization are very mature with large communities using and supporting them. Client virtualization is a much more niche community with unique requirements when compared to those found in the server space. In this talk, we’ll introduce a client virtualization toolstack for Xen (redctl) that we are using in Redfield, a new open-source client virtualization distribution that builds upon the work done by the greater virtualization and Linux communities. We will present a case for maturing libxl’s Go bindings and discuss what advantages Go has to offer for high level toolstacks, including in the server space.

Today Xen is scheduling guest virtual cpus on all available physical cpus independently from each other. Recent security issues on modern processors (e.g. L1TF) require to turn off hyperthreading for best security in order to avoid leaking information from one hyperthread to the other. One way to avoid having to turn off hyperthreading is to only ever schedule virtual cpus of the same guest on one physical core at the same time. This is called core scheduling. This presentation shows results from the effort to implement core scheduling in the Xen hypervisor. The basic modifications in Xen are presented and performance numbers with core scheduling active are shown.
