Yes, as of libvirt 0.8.3.  It isn't yet well documented, but the list 
has had several mails on the topic, such as:
https://www.redhat.com/archives/libvir-list/2010-August/msg00589.html

Meanwhile, what particular command line feature are you missing? 
Ultimately, we would rather add direct libvirt XML support for all qemu 
features, since that is more stable than using <qemu:commandline> at 
your own risk, but without knowing what features people are trying to 
add via <qemu:commandline>, we cannot prioritize which ones to support 
directly in libvirt.
