  5. 5. KVM Overview
  6. 6. 6What is KVM?• A progressive and open source hypervisor driven bythe KVM community, Open Virtualization Alliance andcompanies 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 andSecurity of Linux• Supports advanced hardware assisted virtualizationtechnologies in Intel VT-X and AMD-V X86• Supports Linux and Windows Guests.
  7. 7. 7How 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 withnice, cgroups, numactl, etc.• Implemented as kernel modules‒ kvm.ko: provides virtualization infrastructure‒ kvm_amd.ko and kvm_intel.ko: hardware platform specificmodules
  8. 8. 8KVM ArchitectureAdds “Guest Mode” to Traditional Kernel and User Modes
  9. 9. 9Libvirt overview• Stable API for managing virtualization on a host‒ Storage, network interfaces, networks, host devices,hypervisors, and virtual machines• XML schema for describing configuration ofmanaged 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. 11. Enabling KVM with SUSE Solutions
  12. 12. 12SUSE Virtualization AdvantagesVirtualization Host: SUSE® has the most experience and success inthe virtualization host (hypervisor) market. Supporting both KVM andXEN hypervisors.Virtual Machine Guest: SUSE® Linux Enterprise Server is the “PerfectGuest” on VMware, Microsoft, Citrix and SUSE KVM and XENhypervisor implementations.Virtualization Management: SUSE offers robust management solutionsto simplify the management of physical and virtual machines—acrosshypervisors.Virtual Application Stacks: SUSE Studio is a web application forbuilding and testing software applications in a web browser. It supportsthe creation of physical, virtual or cloud-based applications.Roadmap for the Cloud: Based on Open Stack, SUSE Cloud is anautomated cloud computing platform that helps IT organizationsrapidly deploy and easily manage Infrastructure-as-a-Service privateclouds.
