• Kernel-Based Virtual Machine(KVM) Linux based virtualization For Scale Out POWER8 Linux Servers
• Processor and memory sharing and over commitment enableshigher VM and workload consolidation
• Dynamic addition & removal of virtual devices• Live VM Migration enables higher availability and allows workload
balancing• Exploits P8 Features like Micro-Threading providing greater
scheduling granularity vs x86 virtualization• Exploits performance, scalability and security built into Linux• Managed by PowerVC and open source tools which provides flexible
familiar Linux admin tools• Supports Redhat, SUSE, Ubuntu Linux Guests
PowerKVM v2.1 Open Virtualization Choice for Linux-only Scale-out Servers
Reduces IT Infrastructure costs
Optimize Linux workload consolidation at a lower cost
Simplify your virtualization management using open source tools
Optimize Linux Workload Consolidation and scale out of workloads at a lower cost of ownership
Maintain flexibility and agility by exploiting Open Source Community
Leverage traditional Linux admin skills on Power Systems to administer virtualization
Use open source tools like OpenStack to manage virtualization

PowerKVM Exploits POWER8 Micro-Threading
VM1
Traditional PowerVM and PowerKVM Dispatches the complete core to the VM
CPU Core
PowerKVM with Micro-Threading Dispatches Multiple VMs on a single core at the same time.
SMT1-2
CPU Core 4/1 Division
SMT1-8
VM1 VM2 VM3 VM4
Good for many small VMs / Workloads. Enabled with the PowerKVM ppc64_cpu command. 4/1 Division is only option initially.
