In this HowTo I will describe how to prepare a Fedora 9 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.

This tutorial provides step-by-step instructions on how to install VMware Server (version 1.0.6) on an Ubuntu 8.04 desktop system. With VMware Server you can create and run guest operating systems ("virtual machines") such as Linux, Windows, FreeBSD, etc. under a host operating system. This has the benefit that you can run multiple operating systems on the same hardware which saves a lot of money, and you can move virtual machines from one VMware Server to the next one (or to a system that has the VMware Player which is also free).

In this HowTo I will describe how to prepare a Debian Etch server for OpenVZ.

This week we have tested VirtualBox: a multiplatform virtual machine for x86 machines which allows you to test an OS from a simple .iso image. VirtualBox is easy to install and, just following the instructions contained in its interactive menus, you can setup your virtual OS in few minutes. We strongly recommend to be careful when you decide the quantity of RAM for your virtual OS. It is better to well balance it with the total RAM of your PC. When configuring the virtual HD for your OS it is better to select the "Dynamically Expanding Image" option. By doing this, your virtual OS will use all the hard disk it needs when in use. Last but not least, VirtualBox has a specific virtual USB controller which allows you to connect any USB devices to your virtual machines without installing specific drivers. Strongly recommended for all that people who like to test new OS without formatting their HD each time!

This tutorial provides step-by-step instructions on how to install Xen on an Ubuntu Hardy Heron (Ubuntu 8.04) server system (i386). You can find all the software used here in the Ubuntu repositories, so no external files (apart from a fixed Ubuntu Xen kernel to enable networking for the virtual machines) or compilation are needed.

Quando si creano della macchine virtuali, spesso ricorre le necessità di scambiare file tra il sistema operativo e la macchina virtuale creata. Ci sono varie alternative: penne USB, CD oppure montare un file system.
