Recordings of 23 VMworld Europe Breakout Sessions available free

VMware TV published a couple of recordings of breakout sessions presented at VMworld Europe. The recordings can be watched for free. No account needed.

The interesting thing to note is that VMware seems to be publishing more content of VMware than previously. I believe last year about ten videos were posted. Now sessions that were held at October 23 are put online on the same day. I believe this is very nice and VMware follows Microsoft who publishes content of all TechEd events within 24 hours.

There was an error connecting to VMware vSphere Update Manager fault.hostNotReachable.summary

A customer of mine could not use VMware vSphere Update Manager after some changes in the Active Directory.

They could not enable the vSphere Update Manager plug-in. The icon of VUM disappeared.


I solved this by doing the steps below:

  • Navigate to the folder: C:\Program Files (x86)\VMware\Infrastructure\Update Manager
  • Open with notepad the file vci-integrity.xml and search for the parameter <vpxdLocation>, and make sure the address listed here is the IP-address of the vCenter Server.
  • Save the vci-integrity.xml file
  • Now restart the “VMware vSphere Update Manager Service” service

For some reason an old IP-address was listed although the customer stated the IP-address was not changed.


RVTools 3.5 released!

RVTools is one of the best FREE tools available which helps consultants and system administrators in inventory and managing a VMware vSphere infrastructure. It offers a lot of information on the configuration of storage, network, virtual machines, ESX hosts  and a LOT more. Information can easily be downloaded in CSV format so you can do for example capacity planning. With RVTools you can disconnect the cd-rom or floppy drives from the virtual machines and RVTools is able to update the VMware Tools installed inside each virtual machine to the latest version.

If you do not know RVTools I strongly recommend to download the tool and see for yourself how useful it is and makes your life much easier. You won’t regret.

At March 9 RVTools version 3.5 has been released. New are:


  • On vInfo tabpage new field: Resource pool
  • On vInfo tabpage new field: Consolidation needed.
  • On vCPU tabpage new field: Number of cores per socket
  • New tabpage with resource pool information
  • On vNetwork tabpage new column: Switch name
  • On vNetwork tabpage new column: Starts Connected
  • On vTools tabpage new column: required version
  • On vHost tabpage new columns: custom fields
  • On vDisk tabpage new columns: raw disk information
  • Improved error handling for SSO login problems
  • Bug fix: Invalid snapshot size fixed
  • Bug fix: All datetime fields now use the local time zone
  • Bug fix: data not refreshed after changing filter


vSphere vStorage: Troubleshooting Performance

VMware employee Nathan Small of Global Support  Services published a very good presentation on troubleshooting performance on vSphere vStorage.

The document describes how to read the output given by ESXTop. It stresses the importance of disk alignment to get the most out of your storage array. It discusses SCSI versus SATA drives and a lot more.

This kind of documents will give you a lot of knowledge and I think it is a must read for everyone involed in management and design of VMware vSphere infrastructures.

The presentation be be seen and downloaded at

The agenda is shown below.

vSphere 4.1 Performance Troubleshooting Guide

Duncan Epping of reports that VMware released the Performance Troubleshooting for VMware vSphere 4.1 guide.

The hugely popular Performance Troubleshooting for VMware vSphere 4 guide is now updated for vSphere 4.1 . This document provides step-by-step approach for troubleshooting most common performance problems in vSphere-based virtual environments. The steps discussed in the document use performance data and charts readily available in the vSphere Client and esxtop to aid the troubleshooting flows. Each performance troubleshooting flow has two parts:

  1. How to identify the problem using specific performance counters.
  2. Possible causes of the problem and solutions to solve it

iDatacenter : manage your VMware infrastructure using the iPad

While VMware is still working on an app to manage VMware hosts from the iPad (to be released early 2011), there is already an iPad app available for administering the virtual datacenter from everywhere using the iPad. It is called iDatacenter and is developed by a Swedish company called Nym Networks. The current version is 1.1.1. The first version of the product was released mid 2010.

The application is available at the Apple App Store and costs Euro 11,99 

The following features are supported in the current version of iDatacenter:

•Aggregate statistics per datacenter.
•Individual statistics and status for each physical host, virtual machine.
•Search/filter to find the host or virtual machine you are looking for.
•Use Storage vMotion to migrate a virtual machine from one datastore to another.
•Suspend and power on/off virtual machines.
•Soft reboot and soft shutdown of virtual machine with VMWare Tools installed.
•Enter and exit maintenance mode, disconnect and reconnect, reboot or shutdown hosts.
•Data cache for fast startup and navigation.

More information including a video can be found on the website of Nym Networks, the creator of iDatacenter.
