    $ cp images/linux/Image <tftpboot>/
    $ cp images/linux/xen_boot_tftp.scr <tftpboot>/
    $ cp images/linux/xen_boot_sd.scr  <tftpboot>/

  2. Boot built U-Boot image on the board with either JTAG boot or boot from SD card.
    Note: You can also point the dom1 and dom2 to the domU kernels in the configuration itself so that xen boot files get updated with that pointed images. Edit the configuration file.
    $ vi images/linux/xen.cfg
    $ export XEN_CONFIG="<Absolute path for xen.cfg>"
    $ export XEN_CONFIG_SKIP="1"
    $ petalinux-build -c kernel -x do_deploy
    Note: xen boot files are generated in <plnx-proj-root>/images/linux.
