Virtualization With Xen On CentOS 6.3 (x86_64) (Paravirtualization & Hardware Virtualization)

This tutorial provides step-by-step instructions on how to install Xen (version 4.1.x) on a CentOS 6.3 (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.

Virtualization With Xen On CentOS 6.2 (x86_64) (Paravirtualization & Hardware Virtualization)

This tutorial provides step-by-step instructions on how to install Xen (version 4.1.2) on a CentOS 6.2 (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, but still use the same hardware.

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.

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.

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.

Paravirtualization With Xen On CentOS 5.4 (x86_64)

This tutorial provides step-by-step instructions on how to install Xen (version 3.0.3) on a CentOS 5.4 (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.

How To Enable Networking In Xen Guests On Hetzner's DS Servers (Debian Etch)

This tutorial shows how you can enable networking in Xen guests (domU) on Hetzner's DS servers. With the DS servers, you can get a subnet of eight additional IPs (or more) - usually that subnet is different from the subnet that the server's main IP is from. The problem is that these additional IPs are bound to the MAC address of the host system (dom0) - Hetzner's routers will dump IP packets if they come from an unknown MAC address. This means we cannot use Xen's bridged mode, but must switch to Xen's routed mode where the host system (dom0) acts as the gateway for the guests.

How To Enable Networking In Xen Guests On Hetzner's New EQ Servers (Debian Lenny)

This tutorial shows how you can enable networking in Xen guests (domU) on Hetzner's new EQ servers. With the new EQ servers, you can get up to three additional IPs that are in the same subnet as the server's main IP. The problem is that these additional IPs are bound to the MAC address of the host system (dom0) - Hetzner's routers will dump IP packets if they come from an unknown MAC address. This means we cannot use Xen's bridged mode, but must switch to Xen's routed mode where the host system (dom0) acts as the gateway for the guests.

Paravirtualized OpenSolaris 2008.11 domU Using Debian Lenny

This guide will help you to create an OpenSolaris paravirtualized Xen guest under Debian Lenny.
