Changing text typing repeat delay on a VMware virtual machine
Posted on 17.Mar 2011 by Ray Heffer in ESX, ESXi, Tutorials, VMware, VMwareIf you find that when typing text using the VMware virtual machine console on a low bandwidth connection, it repeats characters (no matter how careful you are). Try setting the following configuration parameter:
keyboard.typematicMinDelay = 2000000
You’ll need to power off your VM first, then add this to the end of your configuration (.vmx) file. If you are using VMware ESX/ESXi then edit the settings of the virtual machine and go to Options then Advanced, General > Configuration Parameters.

ITIL: My take and the impact of virtualisation.
Posted on 15.Sep 2010 by Ray Heffer in Business & IT, ITIL
I’m not an ITIL expert by any means, but I am ITIL v3 Foundation certified and have been working with ITIL projects and service delivery since ITIL v3 was released in 2007. From a technical perspective let’s not forget what service the IT infrastructure is providing. It is all too easy for IT staff to get so wrapped up in the technology; they forget what they are actually delivering as a service to the organisation. ITIL has inspired me to strive for perfection, and take a new approach to delivering technical solutions.
VMware vSphere 4.1 adds more grunt!
Posted on 16.Jul 2010 by Ray Heffer in VMware, VMware
Earlier this week VMware released vSphere 4.1, a significant new version of the industry leading vSphere 4 virtualisation hypervisor. What is interesting is that from September 2010, vCenter management products will be licensed on a per VM basis. This includes: Chargeback, Site Recovery Manager, AppSpeed and CapacityIQ which are currently priced per processor. Products that won’t be included in this licensing change are: vCenter Lab Manager, vCenter Lifecycle Manager, vCenter Server Heartbeat, vCenter Server, and VMware vSphere (ESX).
Running Rings Around Virtualisation
Posted on 01.Feb 2010 by Ray Heffer in VMware, VMware
In 1987 when I was just 11 years old, I used my first real PC, other than the Sinclair Spectrum and Commodore 64 (1984) of course… an Intel 80386 Personal Computer with a green screen CRT display. Bundled with it was a book called ‘80386 Programmer’s Reference Manual‘. Back then I was fascinated with computer programming and machine code, and although little of the book was understood at the time, much of it is still relevant today. The book was published in 1986, and one of the sections covered processor privilege levels.
Privilege levels determine what rights the procedure being executed has when issuing instructions, or accessing I/O ports and memory addresses. There are 4 privilege levels for x86 processor architecture, and these are called rings. The four rings (0 to 3) are designed to protect the hardware resources, keeping user applications at level 3 (the least privilege) and the operating system kernel at ring 0 (the most privileged).
