xen:live-migration_infrastructure [docs]

by camel
In order to be able to do a live migration of a Xen guest from one cluster member to another, some sort of shared storage is required. As the Xen guest won’t run on more than one cluster member at a time, a cluster filesystem is not required. That is, as long as you configure Xen to access the Xen guest by a physical device, not a file.

Cool Solutions: Configuring a Xen VM for Live Migration within a Cluster

by camel
By default, migrating a Xen Virtual Machine (VM) resource causes it to shutdown on the current node and restart on the new one. Once you configure a Xen VM within the High Availability Storage Infrastructure (HASI), how do you configure the Xen VM resource to live migrate among the cluster nodes?

Move an LVM-based virtual machine to another host

by camel
For those running Xen on servers with no back-end SAN, the following instructions detail the steps necessary to move an LVM-based virtual machine to a new physical host. There may be more elegant ways to achieve this, but this is what worked for me.

DRBD 8.0.6 brings full live migration for Xen on DRBD « Florian’s blog

by camel
Undoubtedly, many of you out there are using Xen as the virtualization platform of your choice. Many of you have asked us about doing Xen live migration for DRBD-backed domU’s. Ask no longer, we’ve heard your call. DRBD 8.0.6, released today, contains a block-drbd device helper script for use with Xen. This greatly simplifies the task of integrating Xen with DRBD.

Heartbeat2 Xen cluster with drbd8 and OCFS2

by camel
The idea behind the whole set-up is to get a High availability two node Cluster with redundant data. The two identical Servers are installed with Xen hypervisor and almost same configuration as Cluster nodes. The configuration and image files of Xen virtual machines are stored on drbd device for redundancy. Drbd8 and OCFS2 allows simultaneous mounting on both nodes, which is required for live migration of xen virtual machines. This Article describes Heartbeat2 Xen cluster Using Ubuntu (7.10) OS, drbd8 and OCFS2 (Ver. 1.39) File system. Although here Ubuntu is used it can be done in almost same way with Debian

Xen Live Migration with iSCSI

by camel
This is a document about how to set up XEN and iSCSI on 3 Debian Stable (3.1 / Sarge) machines so that you can have a virtual host that can be migrated live between 2 of the machines. The third machine will be the common disk for the virtual machine that is seen via the 2 machines running XEN. I have assumed you have some knowledge of Linux specifically Debian, but not limited to. You may need to solve some dependencies that I have left out by yourself. I can't think of everything, and I didn't start with completely empty machines.
