SUSE KVM Ecosystem

This document provides an overview of KVM (Kernel-based Virtual Machine) and how it is enabled with SUSE solutions. KVM is an open-source hypervisor that is fully integrated with the Linux kernel and supports hardware-assisted virtualization. It uses QEMU for machine emulation and libvirt for managing virtual machines. SUSE provides support for KVM through SUSE Linux Enterprise Server, SUSE Studio for building virtual appliances, SUSE Manager for centralized management, SUSE Cloud for deploying private clouds, and the High Availability Extension for maintaining high availability of workloads.

- 5. KVM Overview
- 6. 6 What is KVM? • A progressive and open source hypervisor driven by the KVM community, Open Virtualization Alliance and companies like Intel, IBM, SUSE, and Red Hat. • KVM is an acronym for Kernel-based Virtual Machine • Fully Integrated into the Linux Kernel. ‒ Takes full advantages of the Reliability, Availability and Security of Linux • Supports advanced hardware assisted virtualization technologies in Intel VT-X and AMD-V X86 • Supports Linux and Windows Guests.
- 7. 7 How KVM operates • QEMU provides machine and device emulation • Para-virtual drivers used to improve IO performance • Virtual machines are just another process ‒ # qemu-kvm... • Virtual machines (processes) can be controlled with nice, cgroups, numactl, etc. • Implemented as kernel modules ‒ kvm.ko: provides virtualization infrastructure ‒ kvm_amd.ko and kvm_intel.ko: hardware platform specific modules
- 8. 8 KVM Architecture Adds “Guest Mode” to Traditional Kernel and User Modes
- 9. 9 Libvirt overview • Stable API for managing virtualization on a host ‒ Storage, network interfaces, networks, host devices, hypervisors, and virtual machines • XML schema for describing configuration of managed entities • Wide hypervisor support ‒ KVM/QEMU, Xen, LXC, ESX, hyper-v, XenServer, VirtualBox • Used by a wide variety of tools and products ‒ http://libvirt.org/apps.html

- 11. Enabling KVM with SUSE Solutions
- 12. 12 SUSE Virtualization Advantages Virtualization Host: SUSE® has the most experience and success in the virtualization host (hypervisor) market. Supporting both KVM and XEN hypervisors. Virtual Machine Guest: SUSE® Linux Enterprise Server is the “Perfect Guest” on VMware, Microsoft, Citrix and SUSE KVM and XEN hypervisor implementations. Virtualization Management: SUSE offers robust management solutions to simplify the management of physical and virtual machines—across hypervisors. Virtual Application Stacks: SUSE Studio is a web application for building and testing software applications in a web browser. It supports the creation of physical, virtual or cloud-based applications. Roadmap for the Cloud: Based on Open Stack, SUSE Cloud is an automated cloud computing platform that helps IT organizations rapidly deploy and easily manage Infrastructure-as-a-Service private clouds.
