Artikel berikut adalah cara melakukan konfigurasi pada XenServer supaya pada saat kejadian Server mati maka secara otomatis mesin Xen maupun mesin virtual yang ada didalamnya secara otomatis bisa hidup kembali.

Artikel ini belum dicoba, Sebentar lagi insya Allah akan dicoba 🙂

XEN VIRTUAL

Objective

In XenServer versions 6.x, the direct GUI ability to auto-start a Virtual Machine on the startup of XenServer was removed. This article describes how to set Virtual Machines to auto-start.

Xen by IBN

Xen Virtual

Requirements

XenServer version 6.x

Background

In XenServer 6.x, the auto-start functionality was removed because it interfered with High Availability (HA) and produced unexpected results during HA functions.

Instructions

Setting the XenServer to allow Auto-Start

  1. Gather the UUIDs of the pools you wish to auto-start.
  2. To get the list of the pools on your XenServer, run “xe pool-list
  3. Copy the UUID of the pool. If you have just one server, it will still have a pool UUID as noted in the followingUser-added image
  4. Then type the following command to set the pool or server to allow auto-start:
    xe pool-param-set uuid=UUID other-config:auto_poweron=true
    Note
    : Replacing UUID with the UUID of the XenServer or pool.

Setting the Virtual Machines to Auto-Start

  1. Gather the UUIDs of the Virtual Machine you want to auto-start by running xe vm-list.
    Note: This generates a list of Virtual Machines in your pool or server and their associated UUIDs.
  2. Copy the UUID of the Virtual Machines you want to auto-start, and run the following command for each Virtual Machine to auto-start:
    xe vm-param-set uuid=UUID other-config:auto_poweron=true
    Note
    : Replace UUID with the UUID of the Virtual Machine to auto-start.
