That didn't change, your XML should work. I tested it in my environment
and it works as expected. The only thing that I can imagine failing is
the password containing values that break the XML syntax. Try to
surround the value with a CDATA section:


This is good practice, even if it isn't the cause of your problem.

As usual the first step to debug this is to check if the cloud-init
floppy has been generated correctly. Start the VM, go the host where it
is running, locate the qemu process and the location of the floppy img:

  # ps -ef | grep -- '-drive file=/var/run/vdsm/payload/.*\.img'

Make a copy of that file, mount and inspect it:

  # cp /var/run/vdsm/payload/...img /tmp/f.img
  # mount -o loop,ro /tmp/f.img /mnt
  # find /mnt
  # cat /mnt/openstack/latest/user_data
  # umount /mnt
