Introduction to Linux — A Hands on Guide

This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter. For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author’s experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Trying to run some load tests on a website for performance comparisons. I downloaded the SOASTA CloudTest Lite VM (OVA file) because it runs up to 100 cloud-based zombies for free, has some rather nifty-looking graphy-things and a plugin to pull performance data from my server (on AWS).

It’s set up to run on VMWare, but I already have VirtualBox and I really didn’t want to install VMWare Player as well, since it has less features and would be redundant.

Using VirtualBox 4.3.10, I imported the ova. Shown as working on the SOASTA forums here.

Booting in VirtualBox I get this error:

Your cpu does not support long mode. Use a 32bit distribution.

3 seconds of Googling of course uncovers hundreds (maybe thousands!) of people trying to run 64-bit guests without hardware virtualization (VT-x) enabled. Easy fix! But not so fast. My laptop has an i7-2720QM and I’m certain VT-x is enabled in my BIOS; to check my sanity, I open CPU-Z and it shows VT-x enabled. Also, VirtualBox has no problem letting me install a new 64-bit guest (it is limited to 32-bit guest installs if VT-x is not on.)
