      qemu-img rebase · 3e85c6fd
      Kevin Wolf authored
      This adds a rebase subcommand to qemu-img which allows to change the backing
      file of an image.
      In default mode, both the current and the new backing file need to exist, and
      after the rebase, the COW image is guaranteed to have the same guest visible
      content as before. To achieve this, old and new backing file are compared and,
      if necessary, data is copied from the old backing file into the COW image.
      With -u an unsafe mode is enabled that doesn't require the backing files to
      exist. It merely changes the backing file reference in the COW image. This is
      useful for renaming or moving the backing file. The user is responsible to make
      sure that the new backing file has no changes compared to the old one, or
      corruption may occur.
