Why do you even need/want libvirt? I have several machines which run qemu guests just using simple bash scripts to bring them up (and all the bash script is there for is to hold the command line parameters). I like libvirt and virt-manager for configuring and customising the guests, but at the end of the day all that is is a fancy front end to qemu.

If you are stripping the guts out of libvirt, why use it in the first place?
