This is caused by changes in latest version of libgcrypt.

Most people don't hit this because when building with latest gnutls,
libvirt will prefer linking to nettle, instead of libgcrypt. ie linking
to modern gnutls and modern libgcrypt is pretty unusual setup. Are you
perhaps missing nettle-devel packages causing it to fallback to the
legacy libgcrypt codepath ?

None the less we should fix libvirt to not have these libgcrypt errors.
