How to Enable Support for Nested 64bit & Hyper-V VMs in vSphere 5 With the release of vSphere 5, one of the most sought out feature from VMware is the ability to run nested 64bit and Hyper-V guest virtual machines in a virtual ESXi instance. Previous to this, only 32bit virtual machines were supported as the VT-x/AMD-V Hardware Virtualization CPU instructions could not be virtualized and presented to the virtual ESX(i) guest. This feature is quite useful for home and lab setups in testing new features or studying for VMware certifications and running multiple vESX(i) instances. You will still be required to have a 64bit capable system and CPU and you will need to be running ESXi 5.0, this will not work for ESX(i) 4.x or older. The above diagram depicts the various levels of inception where pESXi is your physical ESXi 5.0 hosts. We then create a vESXi 5.0 host which will contain the necessary Hardware Virtualization CPU instructions to support a 64bit nested guest OS which I’ve created as another ESXi host called vvESXi. 1. 2. 3. 2. 3. Intel Hosts: 4. 2.

Running VMware ESX inside a virtual machine is a great way to experiment with different configurations and features without building out a whole lab full of hardware and storage. It is pretty common to do this on VMware Workstation nowadays — the first public documentation of this process that I know of was published by Xtravirt a couple of years ago. But what if you prefer to run ESX on ESX instead of Workstation? You may be pleased to know that the GA build of ESX 4 allows installing ESX 4 as a virtual machine as well as powering on nested virtual machines — VMs running on the virtual ESX host. You can even VMotion a running virtual machine from the physical ESX to a virtual ESX — on the same physical server! VMware vSphere 4.1 UPDATE: VMware ESXi 4.1 has a keyboard issue when virtualized on an ESX 4.0 host. Create a new VM with the following guidance (choose “Custom”): Related posts:

Learn How to Pass (or Beat) a Polygraph Test | AntiPolygraph.org Educate yourself. Before playing Russian roulette with your reputation, learn how to protect yourself against this invalid test. Download AntiPolygraph.org's free book (1 mb PDF): The Lie Behind the Lie Detector The dirty little secret behind the polygraph is that the "test" depends on trickery, not science. The polygraph pens don't do a special dance when a person lies. The test also includes irrelevant questions such as, "Are the lights on in this room?" The simplistic methodology used in polygraph testing has no grounding in the scientific method: it is no more scientific than astrology or tarot cards. Perversely, the "test" is inherently biased against the truthful, because the more honestly one answers the "control" questions, and as a consequence feels less stress when answering them, the more likely one is to fail.

Four ways to disable or enable USB Ports in Windows 7 How often you have witnessed blocked Pen drive or USB drive access in your work place or college or school? I believe many times; in fact every time you try to use the USB drive, you are not allowed, simply because the administrator has disabled USB drive detection on your PC. Again, how often has your data been stolen because someone connected an unauthorized USB to your computer and copied your files? Well, you don’t need to worry because the solution to disable or enable USB Ports is pretty simple. There are three ways an administrator can prevent using of USB Drives. They are: Altering registry values for USB Mass Storage Devices.Disabling USB Ports from Device Manager.By Un-installing the USB Mass Storage Drivers. Lets us look at how we can fix these problems and enable USB on Windows 7 PC. 1. If the administrator is smart then he would definitely do this to ensure a tight blockade.

Windows Hardening Guide - Erik's IT-Security notes Be advised that work on this guide has only just begun. Latest change: 2008-11-29 01 2009 V0.5 Erik Zalitis Security baseline for Windows server 2003 and Windows server 2008 This document describes the steps necessary to harden an already installed Windows 2003 Server installation. Therefore it will not go into detail about the installation process. This is meant to help you create and maintain a minimum security baseline. Checklist Go through this checklist and document every time when you choose not to adhere to the baseline. Installation shall be done on a clean system Reason: Security Baseline for Windows 2003 Server When you upgrade a system, you will get a lot of extra files, leftover registry entries and other remaining data that could affect stability and security. Only one Operating System on the server Reason: Avoid dual boot configurations. English version must be used Reason: Localized Service Packs and software are released later than the native English one. All partitions use NTFS
