ESX 3.5 U3 Scripted Install Improvement
Posted by: | CommentsFor those of us that prefer to script our installs instead of creating hand crafted environments, you’ll be thrilled to see that VMware has addressed a pretty annoying bug that has existed in 3.5 regarding vSwitch creation. No more jumping through hoops to make vmnics active. From the release notes :
Network adapters lose bonding during scripted installation
The esxcfg-vswitch -L command now works as expected and with the same functionality as in 3.0.x.During a scripted installation, the following two commands did not result in a bonded pair of active network adapters on virtual switch VS_VM1. Instead, vmnic3 became the active adapter and vmnic4 became the standby adapter.
esxcfg-vswitch -L vmnic3 VS_VM1
esxcfg-vswitch -L vmnic4 VS_VM1
Interview with Alex Raitz: Splunk for Virtualization Monitoring
Posted by: | CommentsCheck out our latest interview with Alex Raitz from Splunk. Alex and I worked together a few years ago and it was really nice to catch up with him and see how our paths are crossing again.
If you are not familiar with Splunk, it can be described as the IT search engine. It can help you find all kinds of information on any platform and system that generates log files. It’s really flexible and can install on Linux, Windows, UNIX, Solaris, Mac and FreeBSD. If that’s not easy enough, it’s free!
Time Server Source pool.ntp.org
Posted by: | CommentsWhen you need to set a time source for your ESX, XenServers or even Windows servers,
http://www.pool.ntp.org/ is a great and reliable time source. This is an interesting wiki on how it works. Its a really good study on how big DNS deployments are designed http://www.socialtext.net/ntp/index.cgi?dns
Supplemental VI 3.5 Reading
Posted by: | CommentsI am a VMware Certified Instructor, who teaches several classes, including the Install and Configure class, Deploy Secure Analyze class, and the FastTrack class. I teach 50% of the time and perform Professional Services the other 50%. In my opinion, I think the Install and Configure class should include some additional material that I typically find necessary, whenever implementing VI 3.5 for a new customer. So, to accommodate my students, I like to provide a stanadard set of supplemental documents. Some of these are created by New Age Technologies and some by VMware. Take a look and let us know what you think. I plan to update these documents continuously.

vbScript That Reads a List of Servers and Performs an Action
Posted by: | CommentsBetween Windows-centric projects, I usually forget how to get a vbscript to read a text file with a list of servers and perform some action on them. So, I’m posting this one for that functionality mainly. This one happens to look for Network Adapter speeds. The MSDN site is a great resource to see all the Win32 Classes.
This isn’t necessarily pretty and I’m sure there’s better examples, but it gets the job done discovering necessary hardware information for virtualization planning.

Posted by: | CommentsHow to duplicate a complete PC via network
Imagine you get the task to quickly set up a number of identical workstations. Unfortunately either the available removable media (e.g. CD) is too small, or the imaging tool you use insists on not recognizing your favourite file system type (esp. Ext3, XFS, JFS, Reiser), or the duplication won’t work with your bizarre multiboot configuration. Here’s how to do with on-board tools. Read More→
