Virtualization With KVM On A Debian Lenny Server
This guide explains how you can install and use KVM for creating and running virtual machines on a Debian Lenny server. I will show how to create image-based virtual machines and also virtual machines that use a logical volume (LVM). KVM is short for Kernel-based Virtual Machine and makes use of hardware virtualization, i.e., you need a CPU that supports hardware virtualization, e.g. Intel VT or AMD-V.
Managing OpenVZ With The WebVZ Control Panel On Debian Lenny
This guide explains how you can install WebVZ on a Debian Lenny OpenVZ host. WebVZ is a light web-based control panel for OpenVZ. It has its own web server (Webrick) and database engine (SQLITE 3).
Using ATA Over Ethernet (AoE) On Debian Lenny (Initiator And Target)
This guide explains how you can set up an AoE target and an AoE initiator (client), both running Debian Lenny. AoE stands for "ATA over Ethernet" and is a storage area network (SAN) protocol which allows AoE initiators to use storage devices on the (remote) AoE target using normal ethernet cabling. "Remote" in this case means "inside the same LAN" because AoE is not routable outside a LAN (this is a major difference compared to iSCSI). To the AoE initiator, the remote storage looks like a normal, locally-attached hard drive.
Record Installed .deb Packages In A Text File (Ubuntu/Debian)
This short guide shows two methods of recording all your installed .deb packages in a text file that you can then use on another computer to install the same packages there. This is useful if you want to install the same set of packages on more than one computer.
Using iSCSI On Debian Lenny (Initiator And Target)
This guide explains how you can set up an iSCSI target and an iSCSI initiator (client), both running Debian Lenny. The iSCSI protocol is a storage area network (SAN) protocol which allows iSCSI initiators to use storage devices on the (remote) iSCSI target using normal ethernet cabling. To the iSCSI initiator, the remote storage looks like a normal, locally-attached hard drive.
Measuring Linux Latency With LatencyTOP On Ubuntu 8.10 And Debian Lenny
LatencyTOP is a tool that lets you identify where in the system latency is happening, and what kind of operation/action is causing the latency to happen. This article shows how you can use LatencyTOP on Ubuntu 8.10 and Debian Lenny.
How To Run Fully-Virtualized Guests (HVM) With Xen 3.2 On Debian Lenny (x86_64)
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.
Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Debian Lenny)
This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I'll also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota. Passwords are stored in encrypted form in the database. In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV. I will also show how to install SquirrelMail as a webmail interface so that users can read and send emails and change their passwords.
NIC Bonding On Debian Lenny
Ethernet bonding refers to aggregating multiple ethernet channels together to form a single channel. This is primarily used for redundancy in ethernet paths or for load balancing. This page refers in particular to performing ethernet bonding under Linux, and so does not limit itself to discussion of 802.3ad Trunk Aggregation.
Xen Cluster Management With Ganeti On Debian Lenny
Ganeti is a cluster virtualization management system based on Xen. In this tutorial I will explain how to create one virtual Xen machine (called an instance) on a cluster of two physical nodes, and how to manage and failover this instance between the two physical nodes.
