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 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.
Installing KVM Guests With virt-install On Ubuntu 8.10 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 8.10 KVM server.
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.
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.
Installing And Using OpenVZ On Debian Lenny (AMD64)
In this HowTo I will describe how to prepare a Debian Lenny 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.
Installing Xen 3.3 With Kernel 2.6.27 On Ubuntu 8.10 (x86_64)
This tutorial shows how you can install Xen 3.3 on an Ubuntu 8.10 host (dom0). Xen 3.3 is available from the Ubuntu 8.10 repositories, but the Ubuntu 8.10 kernels (2.6.27-x) are domU kernels, i.e., they work for Xen guests (domU), but not for the host (dom0). Therefore we need to build our own dom0 kernel. This guide explains how to do this with a 2.6.27 kernel.
How To Force virt-manager To Use kqemu On Fedora 10
When you use virt-manager to create and manage virtual machines using QEMU as hypervisor you may notice a poor performance on a no virtualization capable processor; this is because by default libvirt (an opensource virtualization API for Xen, KVM, Qemu) ignores the kqemu module (qemu acceleration kernel module). This mini-howto tries to workaround this problem.
KVM & OpenVZ Virtualization And Cloud Computing With Proxmox VE
Proxmox VE (virtual environment) is a distribution based on Debian Etch (x86_64); it provides an OpenSource virtualization platform for running virtual machines (OpenVZ and KVM) and comes with a powerful, web-based control panel (it includes a web-based graphical console that you can use to connect to the virtual machines). With Proxmox VE, you can even create a cluster of virtualization hosts and create/control virtual machines on remote hosts from the control panel. Proxmox VE also supports live migration of virtual machines from one host to the other. This guide shows how you can use Proxmox VE to control KVM and OpenVZ virtual machines and how to create a small computing cloud with it.
Back Up LVM XEN Guest Containing LVs
In my day-job all our Linux boxes (bar 3) are Xen VMs. I wanted a way to take a backup of these with out the risk of the files changing underneath. For performance reasons I am running all of them on Logical Volumes.Within these VMs the DomU OS is once again using LVM for various reasons. This does create some headaches for taking the backup.
