First of all, learn about rebuilding RHEL RPMs from source RPMs.
There are a few guides to do this on the internet (these are in
English -- there may be better Chinese language ones):

  https://wiki.centos.org/HowTos/RebuildSRPM

  https://docs.fedoraproject.org/ro/Fedora_Draft_Documentation/0.1/html/RPM_Guide/ch11s03.html

  http://repoforge.org/package/rebuild.html

Now download the libguestfs source RPM:

If you want the version for RHEL 7.2, then they are now published in
the following CentOS git repository (actually not as a .src.rpm, but
with the spec file and patches extracted, which is more convenient):

  https://git.centos.org/tree/rpms!libguestfs/refs!heads!c7

If you want the source of the preview packages for RHEL 7.3, it is
available here:

  https://people.redhat.com/~rjones/libguestfs-RHEL-7.3-preview/
  https://people.redhat.com/~rjones/libguestfs-RHEL-7.3-preview/libguestfs-1.32.2-6.el7.src.rpm

Make sure you can recompile the source RPM normally.  You *must not*
recompile any RPMs, and especially not the libguestfs RPMs, as root.

Once you are able to recompile the libguestfs RPM normally, you should
now examine the list of patches in the libguestfs.spec file.  In the
RHEL 7.2 version of the spec file, there are 236 patches.  The patch
which you want is called
`XXXX-RHEL-7-Reject-use-of-libguestfs-winsupport-features-.patch' (for
some number `XXXX', which changes with each version).  You should just
be able to comment out this patch line, and recompile.  You might also
need to modify the `Release:' line, in order to give your package a
distinctive build number so you know whether you are using the
official package or your patched package.

Red Hat won't support any packages that you modify in this way.
