It may be caused some packages which are required.
I am not quite sure about that.

I reinstall all the packages required.
As the following:

Libtool (glibtoolize toolize)
Gnutls
Gnutls-devel
Gnutls-c++
libgnutls
pkgconfig(libtasn1)
libgpg-error-devel
libgcrypt-devel
libtasn1-devel
device-mapper-devel/libdevmapper >= 1.0.0
Python-devel
Gettext-devel (autopoint)
Htmldoc
Libxml2-devel
xhtml1-dtds

And remove libvirt source code, then git clone latest source code.
Then I compile it and install libvirt.

It seems that it works.
