4 SUSE Virtualization Virtualization is a key component in SUSE strategy! Xen SUSE first to deliver Xen to the Enterprise in SLES 10 GA SUSE continues to support Xen in SLE 12 KVM SUSE first to deliver KVM to the Enterprise in SLES 11 GA SUSE first to deliver KVM on IBM System z in SLES 11 SP3 4

5 Virtualization use cases In the Clouds Perfect Guest Available in Public Clouds Dual Hypervisor Support Cloud Hosts Host Guest In Your Data Center 5

6 Virtualization Host Full Support for leading open source hypervisors included in the platform KVM and Xen Support for x86, x86_64, IBM System z and POWER8 (Tech Prev) Support for major virtualization features, incl. memory, network or block device hotplugging, VM save/restore, CPU or memory overcommitment, live migration, snapshots Support for OS-level or application virtualization with Linux Containers (LXC) and Docker 6

7 Perfect Guest Perfect Guest strategy, operating system tuned to run great as a guest on all major hypervisors, including VMware ESX Microsoft Hyper-V Citrix XenServer Oracle VM LPAR and z/vm for IBM System z SUSE Linux Enterprise Server with KVM, Xen, LXC and Docker SUSE Cloud Public Clouds 7

8 Virtualization in the Cloud Public Cloud: Broadly deploy SUSE Linux Enterprise Server through SUSE Cloud Service Provider Program Private Cloud: Deliver cloud infrastructure solution powered by OpenStack Hybrid Cloud: Tightly integrate SUSE Studio and SUSE Manager with SUSE Cloud to deliver a platform and tools that enable enterprise hybrid clouds 8

9 Virtualization in the Cloud Ecosystem SUSE Studio Building workloads for physical and cloud environments SUSE Cloud Highly flexible and adaptable cloud infrastructure SUSE Manager - Provisioning - Management - Monitoring SUSE Linux Enterprise The foundation for your datacenter workloads and virtualization 9

10 Virtualization Enhancements in SLES 12

11 SLES 12 Virtualization Continued Xen Support, but with changes Updated Virtualization Packages xen qemu 2.0 kernel 3.12.x (including kvm updates and xenified kernel flavor) libvirt virt-manager virt-install vm-install virt-viewer 1.0 guestfs

12 SLES 12 Virtualization Virtualization Tools v2v tool (Xen to KVM) Extensive v2v documentation Switch to virt-install as default installer SPICE support in tools remote server UI Guest Agent for Linux and Windows 12

13 SLES 12 Virtualization RIP xm/xend Officially deprecated upstream in Xen 4.3 Removed from sources in upcoming Xen 4.5 Managed (or persistent) domains are gone /etc/xen/xend-config.sxp is gone domuloader is gone Support for s-expression config format is gone Welcome xl/libxl (aka libxenlight)! 13

14 xl/libxl Fast, light-weight, improved concurrency Technology preview in SLES 11 SP3 Recommend disabling xend when using xl/libxl Default toolstack in opensuse 13.1 Only toolstack in SLE 12, opensuse 13.2, & Factory 14

15 xend vs libxl xend libxl xm libvirt vm-install xl libvirt state state xend state libxl 15

16 xl vs xm Config Format xm config is a subset of xl Existing xm config should just work with xl Exception: embedded python xl supports a new disk config syntax New features only supported in xl format SPICE, paging options (hap, shadow_memory), device model,... libvirt supports both formats (plus s-expression) 16

17 SLE 11 SP3 Xen SLE 12 Xen Upgrade Export domain config virsh dumpxml > dom.xml Upgrade to SLE 12 Import domain config virsh define dom.xml Or use xen2libvirt utility xen2libvirt recursive /var/lib/xend/domains No live migration of domains from SLE 11 SP3 to SLE 12 host 17

18 SLES 12 QEMU / KVM Highlights General Status of QEMU/KVM: QEMU v2.0 and KVM in v3.12 kernel Available on Intel 64 / AMD 64, IBM System z and POWER 8! Libvirt preferred management layer... QEMU command line supported for access to more features New Features vfio support Linux and Windows Guest-Agent Hotplug vcpus Improved NUMA Support (coming in qemu 2.1 update) Hotplug memory (tech preview with qemu 2.1 update) 18

19 KVM at SUSE Where We Rely on KVM SUSE is exclusively using KVM for its mission-critical servers NIS, NFS, webservers, etc. SUSE Studio uses KVM exclusively Build and Test Drive workers 600,000 users; 7,500 image builds each weak Open Build Service uses KVM guests Build workers 75,000 package builds per day R&D, QA 19

20 Optimized vsphere Guest Performance VMware tools and drivers integrated with SLES 12 for best out-of-the-box experience open-vm-tools vmware_balloon vmw_vmci vmw_vsock vmxnet3 APP SLES 12 Tools Drivers APP SLES 12 Tools Drivers vsphere vmw_pvscsi vmwgfx Fully supported by VMware via L3 support agreement 20

21 Hyper-V Hyper-V - new features supported in SLES 12 - Dynamic memory support - Hot Add and Ballooning - Live VM backup support - Synthetic 2D driver - Dynamic resize of fixed sized VHD - Synthetic fiber channel support 21

22 SLES 12 Supported Guests (1/2) SLES 12 SLES 11 SP3 SLES 10 SP4 SLED 12 (technology preview) OES 2 SP3 OES 11 SP1 NetWare PV 6.5 SP8 (32-bit) RHEL 5 (*) RHEL 6 (*) RHEL 7 (*) 22

24 SUSE Linux Enterprise Virtual Machine Driver Pack VMDP for best guest support Support for SUSE Linux Enterprise Server 12 Support for Microsoft Windows Server 2012 R2 and Windows 8.1 Easier migration from one hypervisor to another (Xen KVM) Simple host to guest access (Windows Guest Agent) Numerous bug fixes and enhancements 24

25 Outlook SLES 11 SP4 Hardware enablement (VMCS shadowing, Haswell) Support latest Hyper-V features (Gen2 VMs, host to guest copy) VMware tools integration Linux guest agent support Amazon EC2-related improvements Update to Xen

26 Outlook SLES 12 SP1 Memory hot plug Hardware enablement (SMAP; System z, POWER) Various improvements (IOMMU, SR-IOV, NUMA) Evaluate management tooling P2V tooling 26

28 Virtualization Enhancements Container Technologies

29 Linux Containers Application container App A Bins/Libs Guest OS App A' Bins/Libs Guest OS System container App B Bins/Libs Guest OS Kernel App B' Bins/Libs Guest OS Kernel Hypervisor (Type 2) Host OS Server 29

30 Why Use Linux Containers? Lightweight virtualization solution Isolated from the other processes 1 kernel to rule them all Normal I/O Dynamic changes possible without reboot Nested virtualization is not a problem No boot time or very short one Isolate services (e.g. web server, ftp,...) Provide root read-only access Mount host / as read-only Add only needed resources read-write 30

31 What's New in SLES 12 Better integration and management of Linux Containers Uses libvirt-lxc framework Same management layer as KVM and XEN Allows for integration with SUSE Manager and SUSE Cloud Unified tooling, independent of the virtualization mechanism SELinux and AppArmor support for LXC Filesystem copy-on-write (btrfs integration) Docker 31

32 What is Docker? Pack, ship and run any application as a container 50+ million downloads 700+ contributors 40,000+ Dockerized apps in Docker s index 128+ meetups over 43 countries 15,000 3rd party projects and partnerships 32

33 SUSE and Linux Containers SLES 11 SP2 introduced Linux Containers (LXC) SP3 brought further enhancements (easy configuration) SLES 12 Introduced Docker Templates for SLE 12, SLE 11 SP3, SLE 11 SP2 KIWI (image building tool) supports Docker as backend Script to create SLE Docker images SLES 12 coming soon (as an update) YaST interface for Docker Easy to get SLES 11 SP3 and SLES 12 Docker images 33
