Re: [libvirt] [PATCH] virDomainBlockStats(Flags): Produce saner error message on empty disk path

As of 0bd2ccdec an empty disk path for virDomainBlockStats (or the one with Flags) is allowed meaning "get me overall summarized statistics". However, running 'virsh domblkstat $dom' throws a misleading error: # ./tools/virsh domblkstat dom error: Failed to get block stats dom error: invalid argument: invalid path: while after this commit # virsh domblkstat dom error: Operation not supported: summary statistics are not supported yet Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com&gt; ---
