Now can now do: virsh vol-resize $vol 10M virsh blockresize $dom $vol 10M to get both interfaces to resize to 10MiB. The remaining wart is that vol-resize defaults to bytes, but blockresize defaults to KiB, but we can't break existing scripts; oh well, it's no worse than the same wart of the underlying virDomainBlockResize. The API for virStorageVolResize states that capacity must always be positive, and that the presence of shrink and delta flags is what implies a negative change. * tools/virsh.c (vshCommandOptScaledInt): New function. (cmdVolResize): Don't pass negative size. (cmdVolSize): Rename... (vshVolSize): ...and use new helper routine. (cmdBlockResize): Use new helper routine, and support new bytes flag. * tools/virsh.pod (NOTES): Document suffixes. (blockresize, vol-create-as, vol-resize): Point to notes.
