How To Set Up A Serial Port Between Two Virtual Machines In VirtualBox

I needed to test serial communication between two VirtualBox guest machines on Linux. This tutorial describes what I did to set up a serial port between two virtual machines running on VirtualBox.

Paravirtualization With Xen 4.0 On Debian Squeeze (AMD64)

This tutorial provides step-by-step instructions on how to install Xen 4.0 on a Debian Squeeze (6.0) system (AMD64) and create paravirtualized guests. Xen lets you create guest operating systems (*nix operating systems like Linux and FreeBSD), so called "virtual machines" or domUs, under a host operating system (dom0). Using Xen you can separate your applications into different virtual machines that are totally independent from each other (e.g. a virtual machine for a mail server, a virtual machine for a high-traffic web site, another virtual machine that serves your customers' web sites, a virtual machine for DNS, etc.), but still use the same hardware. This saves money, and what is even more important, it's more secure. If the virtual machine of your DNS server gets hacked, it has no effect on your other virtual machines. Plus, you can move virtual machines from one Xen server to the next one.

Installing Debian Squeeze (6.0) domU On CentOS 5.5 x86_64 dom0

This tutorial shows how to create a Debian Squeeze (6.0) domU on dom0 running CentOS 5.5 x86_64.

Virtualization With KVM On A Debian Squeeze Server

This guide explains how you can install and use KVM for creating and running virtual machines on a Debian Squeeze 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.

How To Upgrade Debian Lenny (Debian 5.0) To Squeeze (Debian 6.0) On Xen VPS

This tutorial shows how to upgrade a Debian Lenny (Debian 5.0) installation on a Xen based Virtual Private Server (VPS) to Squeeze (Debian 6.0) including kernel update, dependency based boot sequencing and conversion to UUIDs. If you do it the usual Debian way just with apt-get dist-upgrade you will most likely end up with an unbootable system. This is mainly because the update of grub fails.

Installing And Using OpenVZ On Debian Squeeze (AMD64)

In this HowTo I will describe how to prepare a Debian Squeeze server for OpenVZ. With OpenVZ you can create multiple Virtual Private Servers (VPS) on the same hardware, similar to Xen and the Linux Vserver project. OpenVZ is the open-source branch of Virtuozzo, a commercial virtualization solution used by many providers that offer virtual servers. The OpenVZ kernel patch is licensed under the GPL license, and the user-level tools are under the QPL license.

How To Create A LAMP Setup (Apache2, PHP, MySQL) On CentOS 5.x In An Amazon Linux AMI 32bits Or 64bits

This tutorial explains how to create a virtual machine with CentOS 5.x on Amazon's Elastic Compute Cloud (Amazon EC2) and how to set up a LAMP system (LAMP stands for "Linux, Apache, MySQL, PHP") in this virtual machine. We use an AMI (Amazon Machine Image) to set this virtual machine up.

VBoxHeadless - Running Virtual Machines With VirtualBox 4.0 On A Headless OpenSUSE 11.3 Server

This guide explains how you can run virtual machines with VirtualBox 4.0 on a headless OpenSUSE 11.3 server. Normally you use the VirtualBox GUI to manage your virtual machines, but a server does not have a desktop environment. Fortunately, VirtualBox comes with a tool called VBoxHeadless that allows you to connect to the virtual machines over a remote desktop connection, so there's no need for the VirtualBox GUI.

VBoxHeadless - Running Virtual Machines With VirtualBox 4.0 On A Headless Fedora 14 Server

This guide explains how you can run virtual machines with VirtualBox 4.0 on a headless Fedora 14 server. Normally you use the VirtualBox GUI to manage your virtual machines, but a server does not have a desktop environment. Fortunately, VirtualBox comes with a tool called VBoxHeadless that allows you to connect to the virtual machines over a remote desktop connection, so there's no need for the VirtualBox GUI.
