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.

“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

IBM introduced the System/360 (S/360) as a
“new generation of electronic computing equipment”.
IBM unveiled the eServer zSeries 900 – the first
mainframe built from scratch with e-business as its
primary function.
IBM introduced it’s 13th 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.
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.
IBM zEnterpriseSystem
(zEnterprise) is the latest line of IBM
mainframes – now an enterprise systems category solution.
IBM unveiled the most secure Linux servers in
the industry, called
LinuxOne.

History of Unix/Linux
8Megan Hampton | [email protected] | © 2016 IBM Corporation
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
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 2.6.20
Megan Hampton | [email protected] | © 2016 IBM Corporation 9
Allows the Linux kernel to act as a hypervisor
Linux provides the base capabilities
QEMU provides I/O device virtualization and emulation

The Connection
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
KVM for IBM z
Systems allows
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

Standard Management Interface for KVM
Megan Hampton | [email protected] | © 2016 IBM Corporation
Some basic virsh commands:
–virsh define guest.xml
– virsh start VM_NAME –console
– virsh list --all
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

Performance is in Internal Throughput Rate (ITR) ratio based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput that any user will experience will vary depending upon considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, the storage configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve throughput improvements equivalent to the performance ratios stated here.
All customer examples cited or described in this presentation are presented as illustrations of the manner in which some customers have used IBM products and the results they may have achieved. Actual environmental costs and performance characteristics will vary depending on individual customer configurations and conditions.
