1 Introducing KVM for IBM z Systems 1

2 Key Terms Kernel QEMU Hypervisor Mainframe Operating System The central module of an operating system (OS) (Quick Emulator) A free and open-source hosted hypervisor that performs hardware virtualization Also called a virtual machine manager, is a program that allows multiple operating systems to share a single hardware host A large high-speed computer, especially one supporting numerous workstations or peripherals Software that manages all of the hardware resources associated with your desktop or laptop, server or mainframe. 2

3 Agenda Z Systems The Evolution of z Systems Linux History of Unix/Linux The Connection Benefits of KVM Standard management interface for KVM KVM's target audience The future of KVM I want KVM 3

4 z Systems When IBM designed the original mainframe in 1964, it told its customers they would never have to change a line of code. That promise is still true today and remains a major value proposition for IBM customers. Lawrence Miller What is z System? z Systems is a long line of mainframe computers spanning over 50 years. z Systems is comprised of hardware, technological innovations, operating systems, and software designed for critical enterprise applications and processes. 4

5 Evolution of z Systems IBM introduced the System/360 (S/360) as a new generation of electronic computing equipment. April 1964 IBM unveiled the eserver zseries 900 the first mainframe built from scratch with e-business as its primary function. October 2000 IBM introduced it s 13 th high end processor family based on CMOS technology. z Systems (z13 zenterprise) and as a result IBM marked it s anniversary of fifty years of mainframe innovation. April 2014 September 1990 IBM announced System/390 (S/390) - the company s most comprehensive rollout of products, features, and functions in more than a quarter of a century. July 2010 IBM zenterprise System (zenterprise) is the latest line of IBM mainframes now an enterprise systems category solution. August 2015 IBM unveiled the most secure Linux servers in the industry, called LinuxOne. 5

6 Linux Linux is an Operating System (OS) The Linux kernel design is based on Unix Ultimately, Linux manages the communication between your software and hardware Linux is actually everywhere! 6

7 Linux Components of an Operating System (OS) such as Linux: The bootloader Kernel Daemons The Shell Graphical Server Desktop Environment Applications 7

8 History of Unix/Linux In 1968, Ken Thompson and Dennis Ritchie created Unix at Bell Labs. From that point on, a number of side projects started with the vision of Unix in mind A Kernel that took the world be storm! Linux was started in 1991 by Linus Torvalds, a graduate student at the University of Helsinki In 1999, IBM incorporated the Linux port on the Mainframe 8

9 KVM : Kernel-based Virtual Machine A full virtualization solution for Linux on x86 hardware A loadable kernel module The kernel component of KVM is included in Linux since version

10 KVM An Open Source software which Allows the Linux kernel to act as a hypervisor Linux provides the base capabilities QEMU provides I/O device virtualization and emulation 10

11 The Connection KVM for IBM z Systems provides open source virtualization for IBM z Systems and the LinuxONE platforms KVM is an efficient combination of a highly scalable hardware architecture and latest Open Source technology KVM for IBM z Systems allows Reduce operating costs through x86 server consolidation and deployment of Linux workloads Simple installations and standardized Linux administration Sharing of resources Flexibility of using multiple Linux workloads Improving service levels to meet high demands 11

12 KVM Benefits of KVM include An open source tool that runs on all hardware (x86, Power and z) Virtual Machine life cycle and device management Live Guest Mobility / Live Migration Memory/CPU overcommit Accelerates cloud deployments Linux runs seamlessly on a: trusted, scalable, available, and secure platform 12

13 Standard Management Interface for KVM Libvirt is a virtualization management API Libvirt supports several hypervisors such as QEMU/KVM Xen VMWare ESX Provides a simple CLI to define and manage guests Some basic virsh commands: virsh define guest.xml virsh start VM_NAME console virsh list --all 13
