Overview

This guide shows you how to enable XL on a Xen Node.
Note : If there are existing VMs on the Node, you will need to shutdown all VMs.


Requirements

  • Xen 4.1+ installed on a Xen Node
  • Virtualizor 2.6.6+


Stop and Disable XM

You will need to stop and disable Xend to start. For this firstly make sure that all VMs have been shutdown :

root> xm list
Name                                        ID   Mem VCPUs      State   Time(s)
Domain-0                                     0   768     4     r-----  39241.8

Only Domain-0 should be there in this list.

Now lets stop the Xend service :

root> service xend stop

Then prevent / disable it to start the next time.

root> chkconfig xend off

Enable XL in Virtualizor

You will now need to enable XL in Virtualizor for this Node.
