This patch refactors the JSON parsing function that extracts the block IO tuning parameters from qemu's output. The most impacting change concerns the error message that is returned if the reply from qemu does not contain the needed data. The data for IO parameter tuning were added in qemu 1.1 and the previous error message was confusing. This patch also breaks long lines and extracts a multiple time used code pattern to a macro.
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.
