1. European Organization for Nuclear Research Virtualization Review and Discussion Omer Khalid 17 th June 2010

2. European Organization for Nuclear Research Outline Survey Numbers Deployment Use cases What’s available Comparison Proposal Brainstorming and discussion

3. European Organization for Nuclear Research Survey Numbers 60% people already using virtualization 61% own setup, rest CERN Virtualization Service (CVI) Own setup: Image management, CVI Linux configuration issues, problems with sharing files, performance especially disk access, CVI is under heavy load and often request fails (what’s the fallback?), no multi-CPU support for guest OS. 39% of the remaining 40% expressed interest Only 25% are very satisfied, the rest some what. Vendors: Main: VMWare, Oracle Virtual Box Misc: Virtual PC, Xen and KVM (Linux), Parallels (Mac)

4. European Organization for Nuclear Research Use cases 1.To deploy virtual machines with clean and defined configuration E.g. pre-installed PVSS x.x, Step7 etc etc 2.Easy to setup test environment For various scenarios such as testing PVSS patches Testing of FW components under Linux (some issues related to graphical view) Running various PLC simulators in VM’s with different IP addresses Need for multiple dedicated machines for testing Support for multiple operating systems for cross-platform development 3.Ability to snapshot/rollback and ship the configuration/state of VM 4.Reproduction of a problem reported by users 5.H/W access to the VM E.g. USB access for various configuration

5. European Organization for Nuclear Research What’s available Enterprise solutions VMWare Lab Center Initial evaluation requires some configuration; had some ldap configuration issues but provide nice central portal for user access and image manage The cost will certainly be more than 15k CHF per annum This may not be feasible for us in the long run especially if CERN and BE-CO already have invested in these services Same cost factors for products from Citrix Xen CERN Virtualization Infrastructure Users have issues with Linux, image management, performance under heavy load Advantages that it is more sustainable in the long run. It can satisfy some use cases. BE-CO High performance servers with some network gear, total cost > 100k Chf

6. European Organization for Nuclear Research What’s available - 2 BE-CO continued… On-demand virtual desktop infrastructure – no need for desktops Interesting to learn from their experience in the long run Perhaps in the short run, we could use their service Requiring agreement between EN-ICE and BE-CO Standalone products VMWare: Workstation 1.Cost around 160 Euro’s per machine 2.Provides the best set of capabilities including an API for user scripts to start/stop VM’s 3.Image portability between VM Player (free version) Oracle Virtual Box 1.Provides most of the features required by our users 2.But it could be glitchy when it comes to H/W access 3.Free version available as VM Player

7. European Organization for Nuclear Research Comparison Lab CenterCVIBE-COWorkstationVirtual Box Cost User portal Long term Features Use cases Legend: Cost factor: less then 10k Chf per annum User portal: A central place to log in. Remote desktop for Workstaion/V.Box is possible Long term: 3-5 years in terms of cost of and maintenance efforts Features: VM deployment, Memory/Cpu configuration, image migration, Image saving. No inclusion for live VM migration and other fancy features. Use cases: USB access to H/W

8. European Organization for Nuclear Research Proposal Using matrix of solutions CVI and BE-CO setup for quick VM testing where only Win XP is required Setting up a small cluster for EN-ICE With VMWare Workstation on high-end machines Able to 5-6 VM’s per server Repository of pre-configured PVSS, Step7, OPC images Local setup for individual users For use cases where H/W access is required to the machine Either using Vmware Workstation or Virtual Box Setting up an EN-ICE wide guidelines Which solution to use for what particular type of use cases Ideally some where on a wiki so that user’s can follow through on their own Focusing on one or two vendors so that it’s easier to maintain and share images

9. European Organization for Nuclear Research Conclusion All of the use cases can be met Using CVI/BE-CO, EN-ICE virtualization cluster (processing) and local setup’s VMWare only currently supports Windows, Linux and Mac systems. Very useful for image migration between machines running different OS. Buying a batch of VM/W licenses (10, each 160 Eur) Setting up a test bed and to test drive trial versions Defining clear guidelines for types of use cases Identifying image managers in each section Uploading it to an image repository e.g. PVSS related, Step7, OPC etc etc Inviting working group members to test this setup for their use cases Once ready, rolling it out incrementally to all sections Open Discussion - Questions
