Well . .some free training . . and no . . not VCDX or anything too exciting, but VMware have at least provided some online training / eBooks to help all those people who will soon need to transition to ESXi, from ESX (ESX of course will be end of lifed soon)

On blogs:

Great news for all VMware customers: the VMware Education Services team has just made available a new, FREE elearning course dedicated to ESXi , “Transition to ESXi Essentials”. The course is a self-paced three-hour online training that provides the knowledge necessary to make fundamental design decisions to successfully add VMware ESXi to a vSphere environment and to take advantage of all of the new features included in ESXi 4.1. The training is ideal for system administrators, consultants and engineers responsible for managing and supporting a vSphere environment.

VMWare workstation 7.14

April 20th, 2011 No comments

It totally slipped me by, but VM workstation 7.1.4 was released on 29/03/2011.
Of course, you’re all aware that 7.1.3 was uhhh OK at best, but I have not really had many problems with 7.1.4.

Most of the release updates seem to be Linux related, but the Workstation seems to behave a little better than before.

You can download it here:

(you need a license of course)

Resolving connection / initialization problems with VCOPs

April 15th, 2011 No comments

The appliance seems to be very particular about DNS in the environment where it runs. Anything short of perfection may cause one or both of the problems below.

Problem 1: You install the appliance, but can’t connect to it. The browser returns “connection reset” or “unreachable” (depends on the browser). If you used another client system, and it worked, and you connected the appliance to your VCenter, the original system’s VCenter Client still shows that the plugin is disabled due to connection error. Network dump shows that the TCP handshake succeeds, but the appliance resets the connection after the first HTTPS packet.

Cause: The appliance is configured using default SUSE security settings, which include “ALL : KNOWN” line in /etc/hosts.allow. This line dictates that the client IP must be reverse resolvable to a name and then back from the name to the same IP. If your environment doesn’t have reverse DNS that matches exactly with direct DNS, the check may fail, and the server will close the connection.

Resolution: Use the console to connect to the command line (login as “root” / “admin”), and change the above line to “ALL : ALL”. You need to know how to use vi.

Problem 2: You have connected to the appliance, the plug-in works, but the appliance screen is stuck on initialization.

Cause: The appliance can’t resolve its own name.

Resolution: If you use DHCP for the appliance: use the admin web page to disconnect the appliance from VCenter, give the appliance a static IP, create an A record for it in your DNS system, reboot, reconnect to VCenter. If you gave the appliance a static IP: make sure the hostname you specified is resolvable to the same IP.

How to Install Microsoft SQL Server 2008 for VMware vCenter 4

April 14th, 2011 No comments

I don’t often duplicate work, but have stumbled across what is almost definitely the best setup guide I have seen for configuring a Virtual Center with a SQL 2008 Database – I have used this and referenced it to others several times, so figured I’d share it.

Bob Planker’s at the Lone SysAdmin says:

How to Install Microsoft SQL Server 2008 for VMware vCenter 4

I’ve had cause recently to do several new VMware vCenter installations, and I thought I’d take the opportunity to update our documentation on setting up Microsoft SQL Server 2008. Since new VMware vSphere users often find themselves unwittingly becoming DBAs I thought it might help others if I posted it.

Troubleshooting VMware issues with MindMaps

April 7th, 2011 No comments

The guys on VMTN have released a few new mindmaps to help with various bits of troubleshooting.
Initially, I thought, great, another flowchart . . but I run a few scenarios through my lab, thinking that instead of troubleshooting myself, I would simply follow the mind map and I was surprised at how well they cover the kind of problems we see both regularly on our various environments and also how well they cover issues that I regularly see on the VMware communities site.

Oddly, I had never spotted these before – but it seems there are a bunch available at

Below are the 4 that I figure are going to be most pertinent in current environments – a very hany tool indeed.

Mindmap – vSphere Troubleshooting Network Issues
Mindmap – vSphere Troubleshooting Management Issues
Mindmap – VMware Troubleshooting View Management Issues
Mindmap – VMware Update Manager Issues

What I really like about these is not simply that they produce a ‘flow chart’ for troubleshooting, but the fact that once you get to the lowest level on the mind map, there is a little infinity sign that you can click on – which takes you to a knowledge base article for each solution. this means that just about anyone, no matter what their level, can use these
