XPDDS19 Keynote: Xen Dom0-less - Stefano Stabellini, Principal Engineer, XilinxThe Linux Foundation
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.
This presentation is prepared for anyone that needs to basic information about Microsoft virtualization solutions and VDI solutions on Hyper-V, Remote protocols and compatible devices.

Mastering kvm virtualization- A complete guide of KVM virtualizationHumble Chirammal
Mastering KVM virtualization is a complete guide to understand KVM virtualization. Mastering KVM Virtualization is a culmination of all the knowledge we gained by
troubleshooting, configuring and fixing bug on KVM virtualization. We
authored this book for system administrators, DevOps practitioners and developers who have
a good hands-on knowledge of Linux and would like to sharpen their skills of open
source virtualization. The chapters in this book are written with a focus on practical
examples that should help you deploy a robust virtualization environment, suiting
your organization's needs. Our expectation is that, once you have finished the book,
you should have a good understanding of KVM virtualization, its tools to build
and manage diverse virtualization environments.
Hypervisors and Virtualization - VMware, Hyper-V, XenServer, and KVMvwchu
With co-presenter Maninder Singh, delivered a presentation about hypervisors and virtualization technology for an independent topic study project for the Operating System Design (EECS 4221) course at York University, Canada in October 2014.
Virtualization, briefly, is the separation of resources or requests for a service from the underlying physical delivery of that service. It is a concept in which access to a single underlying piece of hardware is coordinated so that multiple guest operating systems can share a single piece of hardware, with no guest operating system being aware that it is actually sharing anything at all.
The virtualization can be described in a generic way as a separation of the service request from the underlying physical delivery of that service. In computer virtualization, an additional layer called hypervisor is typically added between the hardware and the operating system. The hypervisor layer is responsible for both sharing of hardware resource and the enforcement of mandatory access control rules based on the available hardware resources.
There are three types of virtualization: full virtualization, para-virtualization and operating system level (OS-level) virtualization.
Kernel Based virtual machine setup easily on Linux operation systems. It is basically done on Ubuntu operating system.
Anyone with small knowledge of operating Ubuntu can set up it.
The talk is about operating system virtualization technology known as OpenVZ. This is an effective way of partitioning a Linux machine into multiple isolated Linux containers. All containers are running on top of one single Linux kernel, which results in excellent density, performance and manageability. The talk gives an overall description of OpenVZ building blocks, such as namespaces, cgroups and various resource controllers. A few features, notably live migration and virtual swap, are described in greater details. Results of some performance measurements against VMware, Xen and KVM are given. Finally, we will provide a status update on merging bits and pieces of OpenVZ kernel to upstream Linux kernel, and share our plans for the future.

The Xen Project supports some of the biggest clouds in production today and is moving into new industries, like security and automotive. Usually, you will use Xen indirectly as part of a commercial product, a distro, a hosting or cloud service and only indirectly use Xen. By following this session you will learn how Xen and virtualization work under the hood exploring high-level topics like architecture concepts related to virtualization to more technical attributes of the hypervisor like memory management (ballooning), virtual CPUs, scheduling, pinning, saving/restoring and migrating VMs.
In a traditional Xen configuration domain 0 is used for a large number of different functions including running the toolstack(s), backends for network and disk I/O, running the QEMU device model instances, driving the physical devices in the system, handling guest console/framebuffer I/O and miscellaneous monitoring and management functions. Having all these functions in one domain produces a complex environment which is susceptible to shared fate on the failure of any one function, has complex interactions between functions (including resource contention) which makes it difficult to predict performance, and has limited flexibility (such as requiring the same kernel for all device drivers).
""Domain 0 disaggregation"" has been discussed for some time as a way to break out domain 0's functions into separate domains. Doing this enables each domain to be tailored to its function such as using a different kernel or operating system to drive different physical devices. Splitting functions into separate domains removes some of the unintentional interactions such as in-domain resource contention and reduces the system impact of the failure of a single function such as a device driver crash.
Although domain 0 disaggregation is not new it is seldom used in practise and much of its use is focussed on providing enhanced security. Citrix XenServer will be moving towards a disaggregated domain 0 in order to provide better security, scalability, performance, reliability, supportability and flexibility. This talk will describe XenServer's “Windsor” architecture and explain how it will provide the above benefits to customers and users. We will present an overview of the architecture and some early experimental measurements showing the benefits.
With the introduction of virtualization extensions on ARM processors, the Xen community has taken steps to add ARM support for ARM CPUs to the Xen Hypervisor. This port is executed as part of of the Hypervisor project, with no separate codebase.
Xen engineers will describe the key challenges they have overcome, current technical status and discuss about the next steps.

Shining the Enterprise Light on Shades of SocialNovell
2010 has brought an explosion of new social tools to the market, creating a drone of news and conversation that artificially singles out “social” as a stand-alone solution—and for enterprises, a solution to what? When you peel back the category “social,” what capabilities are we really talking about and which ones are missing when it comes to forming a solution that can truly help people in the workplace be more effective?
Learn how to cut through the noise and gain a framework for thinking about the relevance of new tools to their workplace objectives and workplace realities. Attendees will leave this session with a better understanding of use cases and best practices as well as guidance for determining whether a given solution is worth exploring for their enterprise.
