The Xen has a tracing infrastructure that can collect a large amount of very detailed data about what's happening at the hypervisor layer. But making sense out of that data isn't an easy thing to do. In this talk I give an overview of xenalyze, a powerful tool I've developed for finding meaning in the vast amounts of data generated by xentrace, enabling both debugging and performance analysis.

Terms related to security like 'disaggregation' and 'stubdom' have found their way into the standard Xen vernacular. Implementations of these architectures still require heavy lifting but examples have made their way into both the open source and commercial products. In this talk Philip presents a lesser known but complimentary method to confine QEMU processes using SELinux type enforcement. This architecture alone is interesting but Philip believes its utility extends beyond QEMU and SELinux. Future problems like inter-VM communication mechanisms hold unique challenges with regard to access control and policy semantics. Philip will argue that an approach influenced by sVirt and user-space object managers will be useful here. As always, attendees should expect tangents into abstract topics like the nature of trust and the utopic world that strong security mechanisms will bring about.

In this session we examined the Xen PV performance on the latest platforms in a few cases that covers CPU/memory intensive, disk intensive and network intensive workloads. We compared Xen PV guest vs. HVM/PVOPS to see whether PV guest still have advantage over HVM on a system with state-of-the-art VT features. KVM was also compared as a reference. We also compared PV driver performance against bare-metal and pass-through/SR-IOV. The identified issues were discussed and we presented our proposal on fixing those issues.

The Arm architecture allows for a wide variety of cache configurations, levels and features. This enables building systems that will optimally fit power/area budgets set for the target application. A consequence of this is that architecturally compliant software has to cater for a much wider range of behaviors than on other architectures. While most software uses cache instructions that don't need special treatment in a virtualized environment, some will want to directly manage a given cache using set/way instructions and will introduce challenges for the hypervisor to handle them. This talk will give an overview of how caches behave in the Arm architecture, especially in the context of virtualization. It will then describe the problem of using set/way instructions in a virtualized environment. We will also discuss the modifications required in Xen to handle those instructions.

While virtualization technologies like Xen have been around for a long time, it is only in recent years that they have started to be targeted as viable systems for implementing middlebox processing (e.g., firewalls, NATs). But can they provide this functionality while yielding the high performance expected from hardware-based middlebox offerings? In this talk Joao Martins will introduce ClickOS, a tiny, MiniOS-based virtual machine tailored for network processing. In addition to the vm itself, Joao Martins will describe performance improvements done to the entire Xen I/O pipe. Finally, Joao Martins will discuss an evaluation showing that ClickOS can be instantiated in 30 msecs, can process traffic at 10Gb/s for almost all packet sizes, introduces delay of 40 microseconds and can run middleboxes at rates of 5 Mp/s.

NVDIMM is a standard for allowing non-volatile memory to be exposed to as normal RAM, which can be directly mapped to guests. This simple concept has the potential to dramatically change the way software is written; but also has a number of surprising problems to solve. Furthermore, this area is plagued with incomplete specifications and confusing terminoligy. This talk will attempt to give an overview of NVDIMMs from an operating system perspective: What the terminology means, how they are discovered and partitioned, issues relating to filesystems, a brief description of the functionality available in Linux, and so on. It will then describe the various issues and design choices a Xen system has to make in order to allow Xen systems to use NVDIMMs effectively.

Gandi.net is a cloud provider running about 10000 VMs since 2008. We recently updated our infrastructure from Xen 4.1 to Xen 4.8 and decided to move all of our platform to Xen (from a mix of Xen and KVM). This plaform uses home-made code based on Xen python bindings and xl to orchestrate VMs. This talk will present our use cases and the experience we had with Xen, the shortcomings or issues we had while upgrading our platform, what features we use, and present some new features we would like to have in Xen. For example, it will discuss how we use live patching and live migration. The talk will consider both the Xen hypervisor and its associated userspace utilities.

Many people have difficulty understanding the difference between the Xen Hypervisor, XenServer, and XAPI. In this session, James Bulpin, Director of Technology for XenServer, and Russell Pavlicek, Evangelist for the Xen Project, will attempt to clarify what each project is, what it does, and how it compares with the others. We will cover some of the basic features and functions, the tasks for which each is suitable, and where the projects overlap. Attendees will come away with a better sense of where these three projects fit in the world of Xen virtualization.

The motivation of hypervisor based CPUFreq is to enable the one of the main PM use-cases (Dynamic voltage and frequency scaling) in virtualized system powered by Xen hypervisor. Rationale behind this activity is that CPU virtualization is done by hypervisor and the guest OS doesn't actually know anything about physical CPUs because it is running on virtual CPUs. In this talk Oleksandr will briefly describe the possible approach of generic CPUFreq in Xen on ARM, the advantages and disadvantages of having DVFS support on ARM boards powered by Xen hypervisor and share results of his CPUFreq PoC which implies power consumption measurements with and without CPUFreq enabled on R-Car Gen3 based board as an example.

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.

Heather Hedden, Senior Consultant at Enterprise Knowledge, presented “The Role of Taxonomy and Ontology in Semantic Layers” at a webinar hosted by Progress Semaphore on April 16, 2024. Taxonomies at their core enable effective tagging and retrieval of content, and combined with ontologies they extend to the management and understanding of related data. There are even greater benefits of taxonomies and ontologies to enhance your enterprise information architecture when applying them to a semantic layer. A survey by DBP-Institute found that enterprises using a semantic layer see their business outcomes improve by four times, while reducing their data and analytics costs. Extending taxonomies to a semantic layer can be a game-changing solution, allowing you to connect information silos, alleviate knowledge gaps, and derive new insights. Hedden, who specializes in taxonomy design and implementation, presented how the value of taxonomies shouldn’t reside in silos but be integrated with ontologies into a semantic layer. Learn about: - The essence and purpose of taxonomies and ontologies in information and knowledge management; - Advantages of semantic layers leveraging organizational taxonomies; and - Components and approaches to creating a semantic layer, including the integration of taxonomies and ontologies
