===== Installing XenServer via iPXE =====

{{ :logos:xen.png?149x67|Xen logo}}

You can use iPXE to boot into the XenServer installer via HTTP:

  * Create a directory on your web server to contain the installation files (e.g. ''/var/www/boot/xenserver'').

  * Copy the contents of the XenServer installation CD-ROM to this directory.

  * Decompress the files ''xen.gz'' and ''vmlinuz'':<code>
  zcat /var/www/boot/xenserver/boot/xen.gz > /var/www/boot/xenserver/boot/xen
  zcat /var/www/boot/xenserver/boot/vmlinuz > /var/www/boot/xenserver/boot/vmlinux
</code>

  * Create an iPXE script file (''/var/www/boot/xenserver/xen.ipxe'') containing:<code>  #!ipxe
  kernel boot/xen dom0_max_vcpus=1-2 dom0_mem=max:752M com1=115200,8n1 console=com1,vga
  module boot/vmlinux xencons=hvc console=hvc0 console=tty0
  module install.img
  boot
</code>

  * Instruct iPXE to boot from your ''xen.ipxe'' script, e.g. using<code>
chain http://your.web.server/boot/xenserver/xen.ipxe
</code>

  * These instructions are based on the [[http://docs.vmd.citrix.com/XenServer/6.2.0/1.0/en_gb/installation.html#pxe_boot_install|XenServer PXE documentation]].
