Tarry Singh created a video which shows the installation process of VMware ESX3i 3.5.0, quite nice…

Arne Fokkema from ICT-Freak and Gabrie van Zanten from Virtualgabe already mentioned it: VMware ESX3i is available for download at http://www.vmware.com/download/vi/.

It is an ISO-image with the installable for VMware ESX3i.

I already did a quick test with it to see what exactly was made available.

It’s an bootable image (linux installer) and when you try to run it on ESX3.5 you could get the following result(image):

esx3i_in_ESX35

And that’s exactly as far as you will get if you don’t want to wait till Christmas that is.

"Installable" looks a lot like "instable" when you give it a quick look, hopefully it will prove otherwise.

Also tried to install it on a physical workstation, with the bootable installabe on CD the process did run much better than in a VM on the ESX3.5 host. However when reaching the step of installing the software on the box, it came up with the message : "Unable to find a supported device to write the … image to" (see images)

As a real techie it was now time to read the manual, darn only DELL 2950 and HP DL380 G5 are supported/experimental with this version. Unfortunately I hadn’t lying one around so that was all for this experiment for now.

From here in the Netherlands I wish everyone a very happy Christmas and a happy new year!

Massimo Re Ferre’ from IBM wrote an very appealing article usefull for quick impact analytics  – to estimate the cost of a project high fault tolerance looking at the costs deviation of 50% is allowed.

Hardware virtualization these days is a hot topic and we all know that. There are many customers looking into it for the first time and one of the problems they are facing right now is how they are going to size their new virtual infrastructure. Lately I have received lots of requests from many people in order to help them project the hardware investments (in terms of physical servers) that they need to jump onto the virtualization band wagon. In this post I’d like to try to provide you with a very quick and dirty method to do that.

Consider that there are many alternatives to get to a "decent and professional" technical result: you can either hire a consultant for a performance analysis of your current physical infrastructure and have him/her come out with the required hardware infrastructure to support your workload or you can do that on your own with professional tools available in the market (consultants can also leverage these tools and yet provide additional value). These are the best alternatives if you want to come out with a "professional" output that could help you to better present your internal hardware purchase request; please keep this in mind throughout the document. These approaches however could have a few drawbacks:

  • They are time consuming. No matter what, it takes time to gather the data and analyze them to come out with a proper sizing (professional tools can help a lot here)
  • They are expensive. If you want to use these professional tools and/or consultants to do this, it will cost you some dollars/euros to come out with that magic number.

There is no free lunch. The more professional you want to go… the more expensive it gets.

Also take a look at his (somwhat outdated but still usefull) paper about scale up or scale out

This week we tried to clone a vm but when doing so we encountered an error (see screenshot). Whatever we tried we could not figure out what caused the problem.

Cloning Error

At first we thought it was the upgrade to Virtual Center 2.5 that caused the problem, but being in the luckily circumstances having another ESX/VC installation on another site and the ability to test it there without any problem proved otherwise. Our next guess concerned the version of the hosts. Being in the middle of the upgrade to ESX 3.5 + VC 2.5 we still had to upgrade the ESX hosts. So we had an upgraded VC version 2.5 communicating to a couple of ESX hosts who were running on version 3.0.2.

Further testing ruled out any causal connection between the version of ESX/VC and the error we were presented with. In another datacenter within the same Virtual Center instance we could clone a vm without being presented with an error. That left us with the conclusion that the error was to be found at the datacenter or even cluster level. In order to get more information we raised the logging level in Virtual Center, hoping to see an error message telling us why the clone kept failing. I read a thread this week about improved error messaging in the new version of ESX/VC so that was keepoing up the faith. Unfortunately in this case the error messages were not that clear : An unhandled exception occured … etc.

Trying another approach called ‘common sense’ proved to be much more effective. First we looked at the process of cloning. Cloning consist of a number of steps. Which steps are taken and in which part of the process does the error pop up. It turned out that the error popped up at the stage where it should present us with a list of datastores available. Next we analyzed the list of datastores, which also contains the local storage of each host. That was it! One of our ESX-hosts in the cluster was shut down because of hardware failure, but still appeared as member in the cluster (with a red cross). Because repairing the host had taken some time already (and a low priority was given to it) we forgot about it. So the local storage of the cluster resource(ESX host) could not be queried and gave us the error as shown in the screenshot.

Removing the ESX host with the hardware defect from the inventory proved the theory. After the removal we could clone a machine again.

So when running into an error while cloning a VM, take a look at the process of cloning, determine the step in the process where it goes wrong. Take a good look at your inventory, check for hardware defects or connectivity issues with specific components involved.

As Arne Fokkema posted, esiebert has done it again, a couple of months ago he posted a lot of useful links on the VMware VMTN Forum (Community) about ESX 3.0.x and VC. Now again he collected a bunch of links all related to the recently released new versions of ESX and VC.

Take a look at ICT-Freak or the VMware Community for the links.

Also take a look at Mike Laverick’s RTFM-ED.CO.UK website for a free guide he wrote about what’s new  & different in VI(Virtual Infratstructure)3.5

Last Thursday Microsoft released the first public Beta of Hyper-V (a.k.a. Viridian or Windows Virtualization).

This is the link to Windows Server 2008 RC1 with the Hyper-V Beta components:

http://www.microsoft.com/downloads/details.aspx?FamilyId=8F22F69E-D1AF-49F0-8236-2B742B354919&displaylang=en

A couple of video’s with Hyper-V Beta Demo’s:

Video: Symmetric Multiprocessing with Windows Server virtualization (Hyper-V)

Video: Virtual networking with Windows Server 2008 with Hyper-V

Video: Virtual storage for Windows Server 2008 with Hyper-V

Lots of changes since the preview, huge improvements in performance, stability and compatibility as well as:

  1. Support for installing Hyper-V on Windows Server core.
  2. Support for clustering of Hyper-V.
  3. Support for VSS backup of Hyper-V.
  4. Integration Services are now part of Windows Server 2008 (which means that if you use the CD image of this beta to install Windows Server 2008 inside a virtual machine – Integration Services will automatically be there with no need for you to perform extra steps).

I will post detailed installation instructions soon – but two pointers to get you started:

  1. There are no .MSUs anymore.  Just install Windows, select to install a new server role, and select ‘Hyper-V’.
  2. You need to install using ‘English (United States)’.  If you install with any other language (or flavor of English) Hyper-V will not work.  However – you can change the local / keyboard preferences for your user after installation without any problems.

Thanks to Ben’s Virtual PC Guy, watch his posts for more about Hyper-V…

Today I was noticed that:

This morning, the following press release was announced regarding our official partnership with SAP and SAP’s full support for its applications in 64-bit Windows production environments running on VMware Infrastructure. The new partner status is the result of many long months of hard work on the part of Christoph Reisbeck and his SAP Alliance team.

Responding to Customer Demand, VMware and SAP Establish Global Technology Partnership; VMware Infrastructure Supports SAP(R) Solutions with Both Windows and Linux on Industry-standard Hardware

PALO ALTO, Calif., Dec. 12 /PRNewswire-FirstCall/ — VMware, Inc., the virtualization software leader, today announced that SAP AG will provide immediate full support to its solutions in 64-bit Windows- and Linux-based production environments running on VMware ESX Server. Servers from Dell, Fujitsu-Siemens, HP, IBM and Sun have achieved hardware platform certification for SAP® solutions running on Windows and Linux with VMware ESX Server, a component of the VMware Infrastructure software suite. VMware Infrastructure supports SAP solutions with both Windows and Linux on industry-standard hardware. SAP and VMware will assist joint customers in cooperative support services and problem resolution, backed by a global technology partnership agreement and dedicated support staffing.

"There has been overwhelming customer demand for SAP and VMware solutions. Support of SAP solutions on VMware ESX Server means customers can extend the numerous benefits of infrastructure virtualization to the business-critical and functionally rich SAP solutions in their IT environments," said Brian Byun, vice president of global partners and solutions at VMware. "This support reflects the increasingly productive relationship between SAP and VMware, and it provides a sought-after solution for customers looking to combine the powerful process management capabilities of SAP solutions with the robust data center management and cost-saving features of VMware Infrastructure."

SAP solutions enable organizations of all sizes to manage business- critical processes using an enterprise service-oriented architecture (enterprise SOA) to quickly translate customer signals into operational response, respond faster to business and market changes, and provide built-in application integration. Customers who rely on SAP solutions to keep their businesses moving forward can deploy VMware ESX Server with SAP support for all stages of the software lifecycle from development and test to production.

VMware Infrastructure allows customers to turn industry-standard hardware into OS- and hardware-agnostic enterprise-class virtual infrastructure where entire server, storage and network farms can be managed as a shared utility and dynamically allocated to different business units or projects. This gives IT decision makers the ability to combat the continually escalating data center infrastructure and administrative costs incurred from hardware acquisition, management, power and cooling, real estate and disaster recovery; transform IT service levels; and simplify and automate their IT infrastructure.

"VMware Infrastructure has many benefits for hosted environments," said Benno Weidmann, vice president, hosting infrastructure management at SAP Hosting. "We’ve been able to automate internal business processes and increase service levels to internal customers. In addition, we have reduced costs with consolidation and automation of system deployment, as well as greatly reduced the required hardware for internal training and development systems. Altogether, virtualization helps us to lower costs, develop and automate user services, better manage hardware and software lifecycles, and improve production and capacity planning across a more unified infrastructure."

Customers that have been using VMware ESX Server with SAP solutions are successfully leveraging the benefits of virtualization for mission-critical SAP workloads. Support from SAP will enable customers to further extend the value of running SAP solutions on their virtualized infrastructures.

"Our Dynamic Services offering has been taking advantage of the benefits of VMware Infrastructure for use in SAP solution-based environments for a couple of years now," said Dr. Gregory Smith, director of dynamic services at T-Systems North America. "VMware solutions, combined with our own IP, give us high application availability, high server utilization and agile resource management, making it possible to give our customers using SAP solutions a true utility computing model at a lower cost than our competitors."

"We are very pleased with the results of virtualizing our SAP solutions- based environment," said Dave Swan, senior manager of IS&T Server Operations for EFI. "With VMware VMotion, we can do both scheduled and on-the-fly maintenance with zero downtime. We get excellent stability, as well; we can allocate resources as necessary to meet changing workloads without interruptions to our users. One unplanned benefit that we’ve leveraged to great advantage is the ability to spin up temporary test or proof-of-concept environments quickly, whenever we need them, which eliminates unnecessary delays in the software development cycle. VMware software has changed our whole concept of how to support SAP solution-based infrastructure, and we’re able to serve the company much better than we could before we virtualized."

By supporting its applications in production environments running on VMware ESX Server, SAP enables its customers to capitalize on the robust benefits of infrastructure virtualization, including:

    -- Improved data center automation and management: Customers can more
       easily manage IT resources to boost performance of mission-critical SAP
       solution-based workloads
    -- Business continuity and data protection: VMware Infrastructure reduces
       downtime by automatically restarting virtual machines on different
       physical servers in the event of hardware failure, and the suite
       provides cost-effective, hardware-independent disaster recovery
    -- Reduced server sprawl: Customers can run SAP application layers in
       virtual machines that are consolidated onto fewer, highly scalable and
       reliable enterprise servers, enabling a smaller data-center footprint
       and lowering hardware costs
    -- Quick and easy server provisioning: New virtualized servers can be
       provisioned and new SAP solution-based environments can be set up in
       minutes instead of the hours or days it can take to acquire and set up
       new hardware
 

Customers also will benefit from the opening of the first Virtualization Competency Center (VCC) for SAP solutions in conjunction with AddOn Systemhaus GmbH, a leading consulting company. Situated in Walldorf, Germany, the center will be managed and run by AddOn and will provide customers in Europe, Middle East and Africa (EMEA) with a facility where knowledgeable consultants help design, migrate and then optimize simulated deployments of SAP solutions on VMware Infrastructure.
