Something along the lines of virStorageVolClone(virStorageVolPtr src, virStoragePoolPtr dst, unsigned int flags); Although the common & efficient case will be cloning volumes in the same pool, allowing a pool to be passed in directly, allows us to clone across pools. eg, clone a LVM volume to a NFS file. Basically pool which supports 'create' ought to be usable as a destination pool - at worst we can do a generic 'cp' style clone if the underlying pool doesn't have a more efficient method.
