An installed lighttpd HTTP server can now optionally be started to serve
the boot image with the follow run options.
--load-ipxe-lighttpd run lighttpd automatically (default: off)
--load-ipxe-lighttpd-port <port> TCP port to run lighttpd on (default: 8080)
The install_pxe_bootloader_to_run_dir procedure is required by the tftp
as well as the ipxe load script. Move it to a separate file which is
include by both.
This makes use of the iPXE sanboot command [1] which downloads and
boots an ISO image directly via HTTP. Therefore, your RUN_OPT needs
both
--include image/iso and
--include load/ipxe
NOTE: The webserver serving the ISO image must support ranged requests,
see [2].

iPXE is an open source network boot firmware which supports booting from
a web server via HTTP [1].
The following two parameters can be used to specify the iPXE/HTTP setup:
--load-ipxe-base-dir
This parameter specifies the base directory of the HTTP server from
which the target machine downloads the files.
--load-ipxe-boot-dir
The directory relative to iPXE base dir which contains the iPXE
chainload configuration and all necessary files.
The target machine is expected to request the following iPXE
configuration via HTTP:
http://${HOST_URL}/${ipxe-boot-dir}/boot.cfg
This can be achieved by building iPXE with the following embedded
script:
#!ipxe
dhcp
chain http://${HOST_URL}/${ipxe-boot-dir}/boot.cfg
See also [2] for additional information.
