®Xen Today

~20% enterprise server market share>80% of the Public Cloud is Xen basedWorld's largest virtualization deployments are Xen based

Development Community: over 50 Companies, 25 Universities, from 25 Countries, ~250 developersMore than 20,000 code submissions

Used in Severs, Desktops, Laptops, Storage Appliances, Network Appliances and Smart Phonesx86, IA64, ARM support

®

Xen is great. It’s powerful and easy to use. But most important is the very active community around it.

That was a very big reason for us in selecting Xen.

Xen Powers the World’s Infrastructure Clouds

®Xen Tops Performance Comparisons

Keith Ward, Virtualization Review

“Xen is the Porsche of hypervisors”

“Xen outperforms VMware ESX 3.5 by 41% in user scalability tests.”

®Xen 4.0

Released 12 Apr 2010

Reliability, Availability, Scalability

Enhanced MCA support, blktap2, netchannel2

Memory optimizations

pvops privileged domain support

Fault tolerance for VMs

1515

®Hardware Fault Tolerance

X Restart-HA monitors hosts

and VMs to keep apps running

X Hardware Fault Tolerance

with deterministic replay or checkpointing Xen’s Software-Implemented Hardware Fault Tolerance enables true

High Availability for unmodified applications and operating systems

®Hardware Fault Tolerance

University of British Columbia’s “Remus” project is now in xen 4.0

Smart checkpointing approach yields excellent performanceVM executes in parallel with checkpoint transmission, with all externally visible state changes suppressed until checkpoint receipt acknowledged

Checkpoints delta compressed

Checkpointing possible across wide-area, even for multi-vCPU guests

®SR-IOV

SR-IOV: Single Root IO VirtualizationVirtualization friendly IO devices

High performance, high efficiency, low latency

Enables even the most demanding applications to now be virtualized

Compatible with live relocation via hotplug

World First, demonstrated at Intel Developer Forum in September!

Xen Cloud Platform

2121

®Xen Cloud Platform (XCP)

XCP Expands Xen.org’s scope beyond the core hypervisor, to create a full virtual infrastructure layer for Cloud deploymentsSimplify and streamline use of Xen by Cloud providers and vendors

Promote greater standardisation of components between vendors

Advanced virtual infrastructure to enable Virtual Private Datacenters rather than just Virtual Private ServersMulti-tenant hosts, networking, storage, etc

Promote interoperability between xen-based clouds and other clouds

Drive standards activities via DMTF

Xen Client Initiative

3030

®The Xen Client Initiative

Formed in 2007 to develop Xen for desktop and laptopDevelop enhanced power management, USB, WiFi, WWAN, 3D Graphics, fingerprint reader, multi-touch, etc

Support for latest hardware technologies

Tiny footprint hypervisor, Embeddable in Flash memory or small disk partition

Aiming to make virtualization ubiquitous on client devices...

3131

®Client Hypervisor Benefits

Security, Manageability, Supportability, Auditability

Building Multi-Level Secure systemsRun multiple VMs with policy controlled information flow

● E.g. Personal VM; Corporate VM; VM for web browsing; VM for banking

Trusted hypervisor provides secure isolation

Enables “out-of-band” management and policy enforcement via Service VMsMalware detection, remote access, image update, backup, VPN, etc.

ð Requires a true type-1 hypervisor architecture

ð Xen is ideally suited to this!

®Conclusions

The Xen Community continues to grow from strength to strength

Xen’s architecture makes it #1 in security, with great performance

From Cloud to Client

Xen.org’s role is broadening to develop whole reference platforms, promote standards, interopability
