Archipel Project Main Page HOWTO: Virtual Raspbian on Qemu in Ubuntu Linux 12.10 How to chroot RPI envoronment. Keep in mind this took me so many hours to figure out it's not even funny. I'm not exactly a nix guru by any means of the word. The 1st part sucks as it is how you get the img ready. There are two ways to do it but I found it easier just to do it this way. The hard way is to use gemu to expand the img file and then some fancy fdisk stuff in the image to expand. My Way: I do this part all in windows so if you're a linux user you will need to know how to do dd and other linuxy things. Download the latest Raspbian 2013-02-09-wheezy-raspbian.img from unzip it. Write to your SD Card [8 gig is plenty ] I use win32diskimager Once completed insert SD into your RPI and boot it. Run through initial setup screen paying attention to the "expand rootfs" as this one is really the only one of two parts that matter. Exit and reboot log in !!

The script takes snapshots of live running virtual machines, backs up the master VMDK(s) and then upon completion, deletes the snapshot until the next backup. This script has been tested on ESX 3.5/4.x/5.x and ESXi 3.5/4.x/5.x and supports the following backup mediums: LOCAL STORAGE, SAN and NFS.

Logical Volume Manager (Linux) LVM is a logical volume manager for the Linux kernel that manages disk drives and similar mass-storage devices. Heinz Mauelshagen wrote the original code back in 1998, taking its primary design guidelines from the HP-UX's volume manager. LVM is commonly used for the following purposes: Managing large hard disk farms by allowing disks to be added and replaced without downtimes and services disruption, in combination with hot swapping.On small systems (like a desktop at home), instead of having to estimate at installation time how big a partition might need to be in the future, LVM allows file systems to be easily resized later as needed.Performing consistent backups by taking snapshots of the logical volumes.Creating single logical volumes of multiple physical volumes or entire hard disks (somewhat similar to RAID 0, but more similar to JBOD), allowing for dynamic volume resizing.the Ganeti solution stack relies on the Linux Logical Volume Manager The LVM can:
QEMU virtuallyGhetto VE Oracle VM VirtualBox Home » OpenStack Open Source Cloud Computing Software High Availability Cluster Proxmox VE High Availability Cluster (Proxmox VE HA Cluster) enables the definition of high available virtual machines. In simple words, if a virtual machine (VM) is configured as HA and the physical host fails, the VM is automatically restarted on one of the remaining Proxmox VE Cluster nodes. The Proxmox VE HA Cluster is based on proven Linux HA technologies, providing stable and reliable HA service. Update to the latest version Before you start, make sure you have installed the latest packages, just run this on all nodes: aptitude update && aptitude full-upgrade If you run HA, only high end server hardware with no single point of failure should be used. Fully configured Proxmox VE 2.0 Cluster, with at least 3 nodes (maximum supported configuration: currently 16 nodes per cluster). It is essential that you use redundant network connections for the cluster communication (bonding). Adding and managing VM´s and containers for HA should be done via GUI.
