Re: [libvirt] [PATCH 4/4] storage: Add checks for buildVol create file

The buildVol function can fail in numerous ways, but for cleaner or clearer error path handling we want to know whether the calls we made actually created the volume prior to blindly deleting the volume. It could very well be that in between refreshing the pool, checking whether the volume was already in the pool, and trying to create the volume that something 'external' created a volume of the same name. In this case, failure is likely and since we didn't create the volume we shouldn't delete it either. This patch may set the 'created' boolean for the following functions: virStorageBackendCreateQemuImg (in virStorageBackendCreateExecCommand) virStorageBackendCreateQcowCreate (in virStorageBackendCreateExecCommand) virStorageBackendCreateFileDir (in virDirCreate) virStorageBackendCreateRaw (in virFileOpenAs) virStorageBackendRBDBuildVol virStorageBackendSheepdogBuildVol
