devtest report error after adding '--enable-serial-console' to DIB_COMMON_ELEMENTS

We are deploying tripleo on ubuntu 14.04. In order to login the VMs by 'virsh console', we added '--enable-serial-console' to DIB_COMMON_ELEMENTS.
(I found the create-node script checked this, wondering if this is the right way to do this.)
This works good with devtest_testenv.sh and devtest_seed.sh, the VMs' xml added the following lines:
"
    <console type='pty'>
      <target type='serial' port='0'/>
    </console>
"
But devtest_ramdisk.sh and devtest_undercloud.sh reported error:
"
+ acquire-image /home/j/tripleo/deploy-ramdisk-ironic /home/j/tripleo/diskimage-builder/bin/ramdisk-image-create -- -a i386 ubuntu deploy-ironic stackuser common-venv use-ephemeral pypi -u --offline --enable-serial-console

The image-create scripts use DIB_COMMON_ELEMENTS as arguments, should we deal with DIB_COMMON_ELEMENTS before passing it to other scripts or we have a better way to enable serial console?

 DIB_COMMON_ELEMENTS should be add for 'enable-serial-console' not ''--enable-serial-console''.

Didn't notice that, I will try this.
