Virtualization Enhancementsin SLES 12

11

SLES 12 Virtualization

• Continued Xen Support, but with changes

• Updated Virtualization Packages‒ xen 4.4.1

‒ qemu 2.0

‒ kernel 3.12.x (including kvm updates and “xenified” kernel flavor)

‒ libvirt 1.2.5

‒ virt-manager 1.0.1

‒ virt-install 1.0.1

‒ vm-install 0.8.32

‒ virt-viewer 1.0

‒ guestfs 1.26.3

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

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)!

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

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)

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

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)

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

20

• 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

– vmw_pvscsi

– vmwgfx

• Fully supported by VMware via L3 support agreement

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

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

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

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
