How To Run Fully-Virtualized Guests (HVM) With Xen 3.2 On Debian Lenny (x86_64)

Post date: March 8, 2009, 13:03 Category: Installing Views: 3924 Comments
Tutorial quote: This guide explains how you can set up fully-virtualized guests (HVM) with Xen 3.2 on a Debian Lenny x86_64 host system. HVM stands for HardwareVirtualMachine; to set up such guests, you need a CPU that supports hardware virtualization (Intel VT or AMD-V). Hardware virtualization allows you to install unmodified guest systems (in contrast to paravirtualization where the guest kernel needs to be modified); that way you cannot only virtualize OpenSource operating systems like Linux and BSD, but also closed-source operating systems like Windows where you cannot modify the kernel.

DOS Emulation Under Linux

Post date: May 1, 2005, 17:05 Category: Emulation Views: 3126 Comments
Tutorial quote: Whether you need to run some legacy corporate application, or just want to play some of those old classic DOS games, it's easy to get going.

I've done this on a Slackware 9.1 Linux system with a 2.4.22 kernel, running KDE 3.1.4. The process should be very similar for most reasonably recent Linux distros.

Classic AmigaOS Emulation - A Guide for WinUAE

Post date: June 12, 2005, 23:06 Category: Emulation Views: 3640 Comments
Tutorial quote: WinUAE has reached a "v1.0 public"-state (!) and includes many improvements including OpenGL/DirectX display filters (for enhancing graphic output), Catweasel support (hardware for reading classic Amiga formatted diskettes with today's diskdrives) and an overall more cleanly designed user interface. For most people who are unfamiliar with AmigaOS and the use of Amiga emulators, setting up a usable AmigaOS emulation environment can be a daunting task. I have often heard of even veteran computing professionals feeling like complete computing newbees again when being confronted with all the Amiga jargon floating around on Amiga forums. With this article I intend to help provide information and pointers to resources for getting familiar with classic Amiga emulation while focussing on the freely available WinUAE emulator for the Windows platform. With this guide setting up an advanced classic emulation environment shoulld be possible for any PC user.

This article also includes many WinUAE screenshots, videos and information on acquiring and using freely available software.

Choosing an I/O Scheduler for Red Hat Enterprise Linux 4

Post date: July 18, 2005, 22:07 Category: Benchmarks Views: 7444 Comments
Tutorial quote: The Linux kernel, the core of the operating system, is responsible for controlling disk access by using kernel I/O scheduling. Red Hat Enterprise Linux 3 with a 2.4 kernel base uses a single, robust, general purpose I/O elevator. The 2.4 I/O scheduler has a reasonable number of tuning options by controlling the amount of time a request remains in an I/O queue before being serviced using the elvtune command. While Red Hat Enterprise Linux 3 offers most workloads excellent performance, it does not always provide the best I/O characteristics for the wide range of applications in use by Linux users these days. The I/O schedulers provided in Red Hat Enterprise Linux 4, embedded in the 2.6 kernel, have advanced the I/O capabilities of Linux significantly. With Red Hat Enterprise Linux 4, applications can now optimize the kernel I/O at boot time, by selecting one of four different I/O schedulers.
