 I'll take in your idea.

 I plan on adding "process_capabilities" child element to "host" element of 
  the capabilities XML like the following:

  # virsh capabilities
  <capabilities>
  <host>
  ...
    <process_capabilities>
      <cap name='chown'/>
      <cap name='dac_override'/>
      <cap name='dac_read_search'/>
      ...
    </process_capabilities>
  </host>
  ...

 Is this what you mean?
