Using VMware Fault Tolerance to Protect a Virtualized vCenter machine
Posted by on November 30, 2009
In my lab I have a virtualized vCenter installation, it works well and I’ve had no problems with this configuration in the last year. I wanted to try to build a 2 node demo cluster for my VMUG session and needed vCenter to be protected by FT – so an individual host failure would [...]
vinf.net at 2 years old
Posted by on November 25, 2009
I just noticed that my blog has been running for 2 years and 1 month with the 1st post in October 2007 and that got me thinking.. Ever since my school days I’ve been a compulsive note-taker for my personal and professional life, I have numerous paper notebooks in my study going back the [...]
vSphere Performance Overview Page – This Program Cannot Display the Webpage
Posted by on November 23, 2009
When trying to browse the performance overview tab in the vSphere client you may get this error; “This program cannot display the webpage” However, the advanced tab works ok and you can still build custom charts. Luckily, this is pretty simple to fix, the cause of this problem is that the VMware Virtual Centre [...]
Comparing the I/O Performance of 2 or more Virtual Machines SSD, SATA & IOmeter
Posted by on November 19, 2009
I’m currently doing some work on SSD storage and virtual machines so I need an easy way of comparing I/O performance between a couple of virtual machines, each backed onto different types of storage. I normally use IOmeter for this kind of work but generally only in a standalone manner – i.e I can [...]

Posted by on November 18, 2009
If you are a VCP3 you’ll need to get a move on and upgrade your certification to VCP4 unless you have time to sit (and pay for) some classroom training next year – you need to have passed the exam before December 31st 2009 (i.e in 43 days time!) Also bear in mind there [...]
OS X Expose Clone for Windows
Posted by on November 18, 2009
One of the main things I miss as I switch between a Mac and PC is the lack of decent multi-window manager support in Windows – alt-tab and win-tab are great but I find them cumbersome. A particular bug bear of mine is if you have to manage multiple terminal services sessions to servers/virtual [...]

The esteemed Mr Techhead and I will be presenting on how to build a low-cost lab environment for work, study and play at this month’s VMUG in London. We will be bringing our own equipment and hope to have lots of (working!) demos of what you can do with low-cost server kit and interesting [...]
HP ML115 G5 Autopsy (Motherboard Swap)
Posted by on November 10, 2009
Following on from my iSCSI problems the other weekend one of my cheap vSphere hosts died and wouldn’t respond following a reboot. After some investigation and disassembling it would power-up and spin the fans but switch off after about 15 seconds, as everything is integrated onto the motherboard it wasn’t looking too repairable, one of [...]
