  Well, there is a missing documentation part in the patch.
In what way does having security_model='passthrough',
security_model='mapped' or security_model='none' change the
behaviour of the library compared to not having the attribute at
all.
  Any patch which modifies the API (and the XML is part of the API)
must have a clearly defined semantic, and that definition (and if
possible an example) must be provided in the set of patches for the
documentation.
  We cannot accept a patch whose only semantic is "add a given QEmu
command line argument" because it makes impossible to try to support
the option on other hypervisor or if QEmu end up changing the command
line.

  What is your patch providing in term of API ?
