Yes, you need to install the yajl-devel RPM and rebuild libvirt.

This is because latest QEMU binaries are quite alot of functionality
that is only available via the JSON protocol monitor & libvirt needs
this stuff.

It should mention quite a lot more !  Look at the libvirt.spec.in file
in libvirt GIT and see everything listed in a 'BuildRequires' line. You
will want most of it present when building libvirt.
