OSBF Potsdam 11/7/06 XenSource: Open Source Enterprise Virtualization 2

What is Xen Anyway?

• Open source hypervisor– run multiple OSes on one machine– dynamic sizing of virtual machine– much improved manageability

• Pioneered paravirtualization– modify OS kernel to run on Xen– (applications mods not required)– extremely low overhead (~1%)

• Massive development effort– first (open source) release 2003.– today have hundreds of talented

community developers


What’s All the Fuss About?


Problem: Success of Scale-out

“OS+app per server” provisioning leads to server sprawl

Server utilization rates <10%

Expensive to maintain, house, power, and cool

Slow to provision, inflexible to change or scale

Poor resilience to failures


XenSource Delivers Virtualization Value

Consolidation: fewer servers slashes CapEx and OpEx

Higher utilization: make the most of existing investments

“Instant on” provisioning: any app on any server, any time

Robustness to failures and“auto-restart” of VMs on failure


XenSource

• The trusted leader in next generationcommercial-grade virtualization based on the open source Xen hypervisor

• Founded by Xen creators in 2005• Offices in Palo Alto, Redmond,

Cambridge

• Investors:


What We Do

• Next generation high performance hypervisor• Open source industry standard • Backed by all major systems, software and silicon vendors

• Next generation Multi-OS virtualization platform • Easily Installed, Configured, Managed and Maintained• Packaged, consumable, easy to use, supported• Q3 ’06 general availability

• Lead & maintain the Xen project• Center of the Xen ecosystem• Deliver Xen virtualization solutions


Virtualization Wave is Just Beginning

6% of x86 servershave been virtualized(TWP virtualization study, 2/06)

By 2009, there will be three competitive hypervisor architectures: VMware ESX Server, Xen and Microsoft's hypervisor (0.8 probability).


What’s The Big Deal with Xen?

• Superb performance

• Open sourced

• Backed by a stellar community

• Paravirtualization recognized as the right architecture

Paravirtulization - Xen & Windows Hypervisor

• Tiny efficient hypervisor ideally suitedto hardware virtualization

• Guests co-operate with hypervisor for resource management & I/O

• Device drivers outside hypervisor

• Significant performance gains
