And vice-versa if application is built without DOM0 support and it will crash if run in Xen Paravirt mode. This patch allows the library to be built in such a way that only one version needs to be shipped which is important for distro's like RHEL who want to ship a shared library. And also important for users like Brocade/Vyatta who build one binary that needs to work on bare Linux and in Xen PV mode.
