    Virtualization in the Cloud

    Public Cloud: Deploy SUSE Linux Enterprise

    Server workloads in the public cloud or cloud service provider of your choice.

    Private Cloud: Deliver cloud infrastructure solution

    powered by SUSE OpenStack Cloud

    Hybrid Cloud: SUSE Manager to manage servers

    on premise and in the public cloud. SUSE Studio tools to deploy

    workloads to your on premise, private and public clouds.

    SLES 12 SP1 Virtualization

    Major changes were introduced in SLES12xend libxllxc libvirt-lxcqemu 1.4.1 2.0.2

    Focus for SP1 is on stability! Updated Virtualization Packages

    xen 4.5.1

    qemu 2.3.1

    libvirt 1.2.18.1

  • 12

    SLES 12 SP1 Virtualization

    Numerous bug fixes, but some enhancements... virt-builder

    Rapidly deploy pre-built images

    SPICE support in tools remote server UI Guest Agent for Linux and Windows Updated VMDP, Hyper-V drivers, etc...

  • 13

    SLES 12 SP1 Virtualization

    Xen toolstack changes beginning with SLES12 RIP xm/xend

    Officially deprecated upstream in Xen 4.3 (removed in 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)! Documentation can be found in the Virtualization Guide appendix

  • 14

    xl/libxl

    Fast, light-weight, improved concurrency Technology preview in SLES 11 SP3/SP4

    Not supported, but xend should be disabled when using xl/libxl

    Only toolstack in SLE 12+ Global configuration file:

    /etc/xen/xl.conf Memory autoballooning

    Hotplugging and locking behavior

    SLES 12 SP1 Xen Highlights

    General Status of Xen: Xen 4.5.1

    Libvirt preferred management layer xl supported for thin management (not reflected in libvirt)

    New Features Global libxl configuration file (/etc/libvirt/libxl.conf) Supervisor Mode Access Prevention (SMAP) Improved support for large domains Integration with virtlockd Improved logging control (through libvirt)

  • 17

    SLES 12 SP1 QEMU / KVM Highlights

    General Status of QEMU/KVM: QEMU v2.3.1 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 USB 3.0 support Linux and Windows Guest-Agent Hotplug vcpus, memory, character devices and serial ports Improved NUMA Support Support for native RADOS block devices (rbd)

  • 18

    KVM at SUSE Where We Rely on KVM

    SUSE uses KVM forits 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 week

    Open Build Service uses KVM guests Build workers 75,000 package builds per day

    R&D, QA

  • 19

    Mixed Virtualization Environment?

    SLE 11 and SLE 12? Migration is supported from product to product+1

    SLES12 SLES12SP1

    SLES11SP4 SLES12 No live migration between SLE 11 and SLE 12

    Xen and KVM? Domains can be converted from Xen to KVM...

    virt-v2v Supported for SLE 11 or SLE 12 Xen host

    Conversions are non-destructive as source disk is copied

  • 20

    VMware tools and drivers integrated with SLES 12 SP1 for best out-of-the-box experience

    open-vm-tools (10.0.0) In-tree kernel modules:

    vmware_balloon vmw_vmci vmw_vsock vmxnet3 vmw_pvscsi vmwgfx

    Hyper-V Latest drivers and features supported in SLES

    SUSE works directly with Microsoft to enhance and improve drivers

    Drivers are included with SUSE kernels External Linux Integration Services (LIS) package is not required

    Version numbers (such as LIS 3.5/4.0) are not applicable!

    Linux Containers

    Lightweight virtualization Faster provisioning, less downtime

    Higher virtualization density

    Flexibility and agility Containerized apps can be deployed

    anywhere

    Normal I/O, no congestion

    Near native performance IBM research: http://ibm.com/Search/?q=rc25482

    Advantages of 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

  • 33

    Why Docker?

    Shipping applications everywhere Repository of images

    https://registry.hub.docker.com/ Private repository possible

    Workflow for containers like git Commits; push / pull DevOps oriented

    Better disk usage: changes layers Easy to build new images Allows for image versioning

  • 34

    Docker from SUSE, Fully Supported

    Enterprise-ready Images from trusted source (repository) Full control over your data: on-premise registry,

    authentication Pre-built Docker images

    Operational Efficiency Complementary virtualization of Xen/KVM Btrfs support Higher virtualization density

    Easy-to-use tools YaST interface sle2docker, zypper-docker Portus

  • 35

    YaST module

    Simple solution to get started with Docker Manage the available Docker images Run Docker images Control of running containers

  • 36

    Portus Authentication: control access to your images Easy of use: navigate and search your catalog of images Collaboration: organize your users with teams Auditing: keep everyting under control
