It's because we explictly disable it in RHEL 7 because we don't want to support it for Red Hat's customers. You can see the patches that we add on top of upstream libguestfs here: https://github.com/libguestfs/libguestfs/commits/rhel-7.7 The patch in question is: https://github.com/libguestfs/libguestfs/commit/fb3e89b0fb2d0de3c12a668c0... If you want to use this feature, you'll either have to use Fedora or another non-CentOS distribution, or compile libguestfs yourself from source, or take the CentOS SRPM, comment out the patch, and rebuild it.
