https://bugzilla.redhat.com/show_bug.cgi?id=1332019 This function will essentially be a wrapper to virStorageVolInfo in order to provide a mechanism to have the "physical" size of the volume returned instead of the "allocation" size. This will provide similar capabilities to the virDomainBlockInfo which can return both allocation and physical of a domain storage volume. NB: Since we're reusing the _virStorageVolInfo and not creating a new _virStorageVolInfoFlags structure, we'll need to generate the rpc APIs remoteStorageVolGetInfoFlags and remoteDispatchStorageVolGetInfoFlags (although both were originally created from gendispatch.pl and then just copied into daemon/remote.c and src/remote/remote_driver.c). The new API will allow the usage of a VIR_STORAGE_VOL_GET_PHYSICAL flag and will make the decision to return the physical or allocation value into the allocation field. In order to get that physical value, virStorageBackendUpdateVolTargetInfoFD adds logic to fill in physical value matching logic in qemuStorageLimitsRefresh used by virDomainBlockInfo when the domain is inactive.
