‒ 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
• Fully supported by VMware via L3 support agreement

‒ 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!
• Azure‒ SLES12 Linux RDMA image
‒ Very low-latency network connection
‒ Tuned for HPC workloads

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
