This sounds like a question better directed to libvirt-users@redhat.com.

Usually, that's a sign of you not compiling your self-built version with
the same configure options as the pre-compiled version available from
your distro, coupled with mismatched files.  Nothing at all to do with
qemu.  When asking on the libvirt list, make sure to mention your distro
and the set of options you passed to ./configure when self-building.
