Peter Krempa ede89aab64 security: Don't ignore errors when parsing DAC security labels 
The DAC security driver silently ignored errors when parsing the DAC
label and used default values instead.

With a domain containing the following label definition:

<seclabel type='static' model='dac' relabel='yes'>
  <label>sdfklsdjlfjklsdjkl</label>
</seclabel>

the domain would start normaly but the disk images would be still owned
by root and no error was displayed.

This patch changes the behavior if the parsing of the label fails (note
that a not present label is not a failure and in this case the default
label should be used) the error isn't masked but is raised that causes
the domain start to fail with a descriptive error message:

virsh #  start tr
error: Failed to start domain tr
error: internal error invalid argument: failed to parse DAC seclabel
'sdfklsdjlfjklsdjkl' for domain 'tr'

I also changed the error code to "invalid argument" from "internal
error" and tweaked the various error messages to contain correct and
useful information.

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
