How To Install VMware Player On Ubuntu 11.04/Linux Mint 11

How To Install VMware Player On Ubuntu 11.04/Linux Mint 11

This tutorial provides step-by-step instructions on how to install VMware Player on an Ubuntu 11.04 or Linux Mint 11 desktop system. With VMware Player you can create and run guest operating systems ("virtual machines") such as Linux, Windows, FreeBSD, etc. on your desktop, i.e., you can run multiple operating systems on the same hardware which saves a lot of money.

Virtualization With KVM On A CentOS 6.0 Server

Virtualization With KVM On A CentOS 6.0 Server

This guide explains how you can install and use KVM for creating and running virtual machines on a CentOS 6.0 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.

Monitoring ESX/ESXi Servers

Monitoring ESX/ESXi Servers

The purpose is to highlight the most important topics related to setting up ESX/ESXi monitoring as well as applications hosted within managed virtual machines (a MySQL database is used in this tutorial).

Installing And Using OpenVZ On CentOS 6.0

Installing And Using OpenVZ On CentOS 6.0

In this HowTo I will describe how to prepare a CentOS 6.0 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.

VBoxHeadless - Running Virtual Machines With VirtualBox 4.0 On A Headless CentOS 5.6 Server

VBoxHeadless - Running Virtual Machines With VirtualBox 4.0 On A Headless CentOS 5.6 Server

This guide explains how you can run virtual machines with VirtualBox 4.0 on a headless CentOS 5.6 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.

OpenVZ is the open-source branch of Virtuozzo, a commercial virtualization solution used by many providers that offer virtual servers.

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.

Paravirtualization With Xen On CentOS 5.6 (x86_64)

Paravirtualization With Xen On CentOS 5.6 (x86_64)

This tutorial provides step-by-step instructions on how to install Xen (version 3.0.3) on a CentOS 5.6 (x86_64) system. 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 KVM Guests With virt-install On Ubuntu 11.04 Server

Installing KVM Guests With virt-install On Ubuntu 11.04 Server

Unlike virt-manager, virt-install is a command line tool that allows you to create KVM guests on a headless server. You may ask yourself: "But I can use vmbuilder to do this, why do I need virt-install?" The difference between virt-install and vmbuilder is that vmbuilder is for creating Ubuntu-based guests, whereas virt-install lets you install all kinds of operating systems (e.g. Linux, Windows, Solaris, FreeBSD, OpenBSD) and distributions in a guest, just like virt-manager. This article shows how you can use it on an Ubuntu 11.04 KVM server.
