You won’t want to miss the VMworld Party at the Las Vegas Motor Speedway. You’ll enjoy live entertainment and racing activities where you can speed around the track at 140 mph, race a go-cart, jump on a Big Wheel, or test your pit crew skills. Or, just unwind, enjoy the live entertainment and refreshments, and experience the unique venue.

Version 1.0 of the SVMotion has been released at http://sourceforge.net/projects/vip-svmotion/. New features include:

- No longer counts RDM files against datastore size, fixing the bug that plagued the last version.

- SVMotion operations against templates are not supported since VMware does not support them.

- Added tool tips that explain why a relocation cannot take place

- All SVMotion events write out a log, enabling better understanding of what went wrong in case of an error.

- Aside from the library that loads the plug-in, all of VMware's internal code has been replaced with the VI Toolkit for .NET.

- The project is now supported by almost 20 unit tests, helping to ensure fewer bugs and greater stability.

- The unit tests can be expanded to include testing for a system-resource supported number of servers since they use mock testing designed to work with the VI Toolkit for .NET.

- The project is now built using NAnt, which allows nightly builds of the source, creates distributions, and builds the MSI installer.

Arne Fokkema over at ICT-Freak has written a nice little “how to�?. His post shows all the steps to take so you can get all the historic VMotion info and present it in an Excel sheet. The data is  extracted directly from the Virtual Center database and can be updated any time.

Mike Laverick released another RTFM white paper. This one helps you to get up and running with VMware’s new PowerShell Toolkit – without having to learn any Powershell code!

Mike Lavaerick:

I was initially put of using the various SDKs, Perl Toolkits and PowerShell Tookits – although I’m pretty good with the CLI of an ESX host and write useful “shell�? (.sh) scripts – I wouldn’t say I was a VBS guru or C# guru. Then I discovered PowerGUI. PowerGUI puts a graphical shell around Microsoft PowerShell. It’s a bit like the old style “macro�? recorders you used to get in spreadsheet or a word processor. You click about making changes – and this creates the code you need. Sure if you want to really fancy things like loops and error control you then need higher level knowledge – but this really great for poor little admins like me who’s eyes glaze over once some talks about object, properties, attributes and methods.

vReplicator 2.5 provides some excellent upgraded features to allow customers to leverage software-based replication and virtualization to drive their High Availability and Disaster Recovery strategies. vReplicator 2.5 offers several new major features that support these objectives, including the following:

• VSS (Microsoft Volume Shadow Copy Service) Support to enable quiescing of supported databases to ensure transactionally consistent image backups
• Two Types of Replication:  Differential, which allows customers to backup all the changed data since the last full back up, and Hybrid, to allow customers to schedule shorter replication intervals by backing up only the data that has changed from the last interval backup
• Replication of VMs to Multiple Destinations, which allows a company to accomplish multiple objectives for High Availability and Disaster Recovery
• Ability to Export Reports in Adobe® PDF, XML or Microsoft® Excel formats allowing data to be imported into third-party reporting tools
• Skipping VMDKs, which allows skipping of non-essential disks for faster replication passes

The result of this latest round of upgrades is that vReplicator 2.5 is now faster than ever – up to 10x speed improvements in the typical environment. The new features of vReplicator 2.5 will be outlined in detail during Vizioncore’s vReplicator Overview Webinar on July 3, 2008.

RUSS NAPLES, CITRIX VETERAN, JOINS VIZIONCORE AS SENIOR VICE PRESIDENT OF PRODUCT DEVELOPMENT

Vizioncore is pleased to announce that Russ Naples is the new senior vice president of product development reporting into Vizioncore President and Chief Operating Officer Chris Akerberg effective immediately.
Prior to joining Vizioncore, Naples spent 13 years in increasingly important product development roles at Citrix Systems, beginning as a director in testing and rising to vice president of product development for the company. Before Citrix, Naples served as project lead in General Electric’s Systems Integration, Test and Quality Department and has experience teaching management science courses at the university level.
Naples holds a Master’s in Business Administration from Chapman University in addition to a Bachelor’s Degree in Mechanical Engineering from the Rochester Institute of Technology, and has served on several university advisory boards related to engineering and computer science.

VMware Stage Manager, a break-through product for delivering applications from staging to production is now generally available. VMware Stage Manager solves the problem of server sprawl, configuration drift, and repetitive system testing in pre-production by running IT services and business applications as virtual machine configurations that can be easily transitioned through the release process. VMware Stage Manager allows IT to roll out new and updated applications into production more quickly, avoid the risk of unplanned downtime, and accelerate change requests to production systems.

VMware Stage Manager is available for VMware Infrastructure 3 Standard or Enterprise and can be purchased as part of the VMware Management and Automation and IT Service Delivery bundles, or a-la-carte.

Christoph over at 21st century storage has written a good article about 10 GigE. Here are some quick performance results from VMware servers with 10 Gigabit Ethernet cards (from Sun with an Intel 82598 controller. The servers were Sun X4150 with Dual-Quadcore processors. I fired up two test VMs with Suse Linux Enterprise Desktop 10 (64 bit) and used netperf to measure TCP bandwidth between them (the exact command used was netperf -H <target ip> -t TCP_STREAM -C -c -l 60 -f M).

Generally this is exactly what we expected: to be able to provide good performance to many virtual servers which do network and/or disk-I/O only periodically without overprovisioning the whole infrastructure.

At the moment there is exactly one dual-port 10 GigE card in every VMware server and there are two physical connections to two different switches - a much cleaner setup than the 12 (!) GigE interfaces per server we had before. Via Arne Fokkema over at ICT-Freak.

Sven Huisman is a Technical consultant working for QNH Infrastructure located in Zeist, the Netherlands. Virtualization is his main interest. On this blog Virtualfuture he will write about things he finds on the internet, events that he visits and everything else as long as it is about (or at least related to) virtualization. He has written a nice review about the upcoming VMware ThinApp 4.

After registering for the release candidate, I downloaded the installer. While downloading the installer (only 7 MB) I had plenty of time reading the manual ;-). Before you begin using this product, you might want to ask, what is Thinapp?

The beta 2 of VMware Workstation will contain a permanent fix for this problem but until then you can start a Virtual Machine running in ESX 3.5 hosted on Workstation 6.5. The only thing you have to do is minimize the resources.

From the ESX or VC client, highlight the VM and select > Edit virtual machine settings
Select Resources tab
Un-check Unlimited in the right pane and lower Mhz count to 700
Select Advanced CPU in the left pane
Under Scheduling Affinity in the right pane > Select Run on processor(s):
Check "0"
Click OK to close VM edit window
Boot VM

I'll say this much - this isn't a great fix.  Although it does allow for additional testing, VM performance is dismal at a minimum.  I'm going to play with MHz and Affinity settings to see if I can get better results.
