Xen as High-Performance NFV Platform - Jun Nakajima, Intel

We are building a high-performance NFV (Network Functions Virtualization) platform using Xen. Unlike the conventional use cases of Xen-based systems, such as data center or public cloud, NFV platforms require low-latency and high-bandwidth I/O for virtual middleboxes to handle small packets efficiently. It is challenging to meet such requirements in virtualization environments because of additional virtualization overhead.

We'll discuss a couple of solutions for high-performance packet forwarding, including SR-IOV VF (Virtual Function), shared-memory channels for VM-to-VM communication, resolving the major bottlenecks and latency/realtime issues, taking advantage of the Xen's architecture. We also discuss how the modern hardware-based virtualization features, such as Posted Interrupts, are helpful. Finally we share the best practices when achieving such high-performance systems.

libvirt support for libxenlight - James Fehlig, SUSE

"libvirt is an important piece of the overall open source virtualization management puzzle. Many of the open source virtualization management applications that users enjoy are based on libvirt, since it provides a normalized API for managing heterogeneous hypervisors. For Xen to enjoy this greater ecosystem of open source virtualization tools, it must be well supported and maintained in libvirt.

This presentation will give a basic overview of libvirt, discuss the latest status of the libvirt libxenlight driver (also known as the libxl driver), and discuss future improvements planned for the driver.

Zero-Footprint Guest Memory Introspection from Xen - Mihai Dontu, Bitdefender and Ravi Sahita, Intel

This presentation will detail a practical approach to memory introspection of virtual machines running on the Xen hypervisor with no in-guest footprint. The functionality makes use of the mem-event API with a number of improvements which enable the proper tracking of guest OS activity. The technology created on top of this Xen API opens the door for several immediate applications, including: rootkit detection and prevention, detection and action on several categories of malware, and event source information for low-level post-event forensics and correlation based on real event data during events.

Xenstore Mandatory Access Control - James Bielman, Galois

Mandatory Access Control (MAC) is a security model in which access
decisions are governed by a centralized security policy rather than
the system's users. Systems with MAC are better protected from
malicious or careless users and programs granting permissions that
violate a system's desired security goals.

Xen supports MAC at the hypervisor level via the Flask Xen Security
Module (XSM/Flask), building upon the widely used SELinux
infrastructure. However, other critical components of the Xen
architecture, such as Xenstore, are not covered by the XSM security
policy.

Galois has developed an implementation of mandatory access control for
a disaggregated Xenstore domain. In this presentation, James Bielman
will discuss the implementation of Xenstore's nested security server
in a Mirage-based Xen kernel.

Towards Massive Server Consolidation - Filipe Manco, NEC

In recent years Xen has seen the development of many minimalistic or specialized virtual machines (e.g., OSv, Mirage, ClickOS, Erlang on Xen, etc.). Thanks in part to a small CPU and memory footprints, these VMs allow for running thousands or more on a single, inexpensive commodity server. Doing so could save cloud and network operators vast amounts of money.
Attempts to do so are already underway and have discovered important bottlenecks in Xen. While some of these have already been addressed by the community (e.g., limited number of event channels or memory grants) others still remain. In this talk we describe our experience when trying to run up to 10,000 MiniOS-based VMs, including bottlenecks in the XenStore, toolchain and network pipe. We further report on prototypical solutions, and on our implementation of suspend/resume for MiniOS that allows us tens of milliseconds migrations.

MirageOS 2.0: branch consistency for Xen Stub Domains - Anil Madhavapeddy, Univeristy of Cambridge

"We have been developing a new storage system designed specifically for unikernels such as MirageOS that run in a stub-domain environment. In this mode, domains only have access to raw device rings such as Blkfront, and no ""real"" filesystem.

Our new Irminsule filesystem builds on the principles of Git to give every unikernel the same primitives as a distributed version control systems. Unikernels can attach to shared block devices and pull, merge and push trees of blobs with other unikernels. Conflicts are resolved at the application level via merge functions defined specifically for the usecase at hand, and consistency models can be tailored to reduce the conventional overheads of general purpose filesystems.

Our use is to rewrite OXenstored, resulting in all transactions being reflected as a Git tree, making debugging complex deployments much more tractable and distributed."

Scaling Xen's Aggregate Storage Performance - Felipe Franciosi, Citrix

Storage systems continue to deliver better performance year after year. High performance solutions are now available off-the-shelf, allowing users to boost their servers with drives capable of achieving several GB/s worth of throughput per host. To fully utilise such devices, workloads with large queue depths are often necessary. In virtual environments, this translates into aggregate workloads coming from multiple virtual machines.
Having previously addressed the impact of low latency devices in virtualised platforms, we are now aiming at optimising aggregate workloads. We will discuss the existing memory grant technologies available in Xen and compare trade-offs and performance implications of each: grant mapping, persistent grants and grant copy. For the first time, we will present grant copy as an alternative and show measurements over 7 GB/s, maxing out a set of local SSDs.

Xen in EFI World - Daniel Kiper, Oracle

EFI is a very hot topic now because more and more hardware vendors are providing some new systems with it. The long term goal is a total removal of legacy BIOS support. It means that Xen should be prepared for that case. Indeed it is mostly ready. During this presentation it will be shown what EFI is in real and how Xen and other required pieces use EFI infrastructure. However, there are still some shortcomings in Xen and they will be described too. There will be also some guidance how to efficiently start Xen on EFI platform. Some guests topics related to EFI also will be covered.

An Overview of the Verizon Cloud Architecture - Don Slutz, Verizon

An overview of the Verizon Cloud Architecture and what Xen Features are in use. This will include planned features as well. A major part is the goal of Quality of Service (QoS) in all areas. This includes CPU, Memory, Network, and Disk. Also the network is based on level 2 so is more flexible. We provide a GUI as well as an API (the GUI uses the API for all tasks). Another design goal is to correctly handle scale. We also plan to offer full access to the guest console (VGA and serial). The tool stack is distributed and runs as guests on Xen.

Enhancements to Xen/Qemu required to support seamless import of VMWare guests include: emulation of devices available in VMWare, support for VMWare tools back-door, PCI bridge emulation enhancements, as well as fine-grained control over the placement of PCI devices, CPUID, and PCI hole size.

Xen on ARM: Status and Performance - Stefano Stabellini, Citrix

As the first ARM servers and microservers hit the market, Xen on ARM is becoming more mature, stable and reaching feature parity with x86. This talk will present the current status of the project, will describe the latest improvements, the gaps that still need to be filled and the roadmap going forward. ARMv8 silicon is now available for purchase: we can measure how well Xen on ARM 64-bit is performing on real hardware and compare the performance figures with other hypervisors. The presentation will show these results, it will measure the overhead introduced by Xen on ARM and will compare it with the overhead introduced by Xen and KVM on x86. The talk will explain the reasons behind performance shortfalls and present ideas on how to address them in the future. The performance results will be used to determine when it makes sense to use Xen on ARM and what are the best use cases for it.

Removing the Xen Linux Upstream Delta of Various Linux Distros - Luis R. Rodriguez, SUSE

Xen is being used in production by many folks, but are they really using the upstream code? If not what are they using? At least SUSE's supported delta for the Linux kernel consists of 116 patches totaling 353,770 lines of code. Debian has 43 patches for a delta of about 1693 lines of code. What is this delta and how do we shrink it?

Xen and the Art of Certification - Nathan Studer, DornerWorks

With the rapid growth in computing power of embedded platforms, system designers are turning to hypervisors to consolidate functionality in order to reduce the Size, Weight, Power, and Cost of embedded systems. With the recent addition of ARM support to the Xen hypervisor, Xen provides an attractive Open Source option for such systems. However, some of the industries most interested in this technology, such as automotive, medical, and avionics, have strict safety certification requirements. Nathan Studer will give a brief overview on DornerWorks efforts certifying Xen, describe the hurdles and advantages that Xen and its development model lend to the certification effort, and layout a proposed path for certifying Xen.

Intel(r) Virtualization Technology for Directed I/O (VT-d) Posted Interrupts - Feng Wu, Intel

With the development of virtualization, there are more device assignment requirements. Based on VT-d interrupt remapping, Intel introduces VT-d interrupt posting as a more enhanced method to handle interrupts in the virtualization environment. The Posted Interrupts (PI) on CPU side has been already supported in Intel CPUs, with VT-d Posted Interrupt we can get some additional advantages, it can directly deliver external interrupts to running vCPUs without hypervisor involvement, decease the interrupt migration complexity, differentiate between urgent and non-urgent external interrupt, and avoid consuming host-vector for each interrupt to vCPU. In this presentation, Feng will talk about the mechanism of VT-d PI and its advantages, as well as some performance data of I/O intensive workload in Xen, which will show the performance gain after using VT-d PI.

RT-Xen: Real-Time Virtualization in Xen - Sisu Xi, Washington University

Recent years have seen an increasing demand for supporting real-time systems in virtualized environments. To combine real-time and virtualization, a real-time scheduler at the hypervisor level is needed to provide timing guarantees to the guest virtual machines. RT-Xen provides a suite of multi-core real-time schedulers to deliver real-time performance to domains running on the Xen hypervisor. Work is underway to incorporate RT-Xen in the Xen distribution to replace the legacy SEDF scheduler. We have implemented and empirically compared a diverse set of multicore real-time scheduling policies within the RT-Xen scheduling framework. Based on extensive experiments of different scheduling policies, we plan to submit a patch on global EDF scheduler to the xen-devel as the first step to incorporate multicore real-time scheduling support within the Xen hypervisor.

Porting FreeRTOS to Xen on the ARM Cortex A15 - Jonathan Daugherty, Galois

Autonomous vehicles need to run robust autopilot software in resource-constrained environments. Such vehicles are increasingly built on ARM platforms with resources to spare. We have begun investigating the feasibility of using this spare capacity to implement other interesting services on these vehicles by using Xen to separate the real-time autopilot software from a richer, non-real-time Linux system. In order to make this work, we have ported FreeRTOS, a popular minimal operating system for microcontrollers, to run as a Xen guest on the ARM Cortex A15.

OSv - A Modern Semi-POSIX LibraryOS - Glauber Costa, Cloudius Systems

During last year, we have seen the rise of LibraryOSes in the hypervisor world. Fast, scalable and light, they bring to hypervisors the resource efficiency of Containers while maintaining many of its well known isolation and manageability advantages.

While most LibraryOSes are niche in what they do, OSv is designed to run almost any POSIX compliant application and just have a slight focus in the Java application. Which applications can we run? And why? What's the story with Java and what can users gain from it? And more importantly: How can Xen users and the Xen community at large benefit from OSv?
