openstack-manuals/doc/install-guide/section_nova-networking-compute-node.xml
Christian Berendt a2d662d600 Unified the syntax of the XML root element (install-guide)
The XML root element of Docbook XML files should match the following
format:

<ELEMENT xmlns="http://docbook.org/ns/docbook"
  xmlns:xi="http://www.w3.org/2001/XInclude"
  xmlns:xlink="http://www.w3.org/1999/xlink"
  version="5.0"
  xml:id="THE_XML_ID_OF_THE_ELEMENT">

multiple compute nodes, the <glossterm>multi-host</glossterm> feature
