Instead of having duplicated code in qemuStorageLimitsRefresh and virStorageBackendUpdateVolTargetInfoFD to fill in the storage backing source or volume allocation, capacity, and physical values - create a common API that will handle the details for both. The common API will fill in "default" capacity values as well - although those more than likely will be overridden by subsequent code. Having just one place to make the determination of what the values should be will make things be more consistent. For the QEMU code - the data filled in will be for inactive domains for the GetBlockInfo and DomainGetStatsOneBlock API's. For the storage backend code - the data will be filled in during the volume updates. Signed-off-by: John Ferlan <jferlan@redhat.com>
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.
