I was thinking about it last week. AFAIK, libvirt-java 0.5.1 does not support change setting on running vms, but virsh command line and libvirt API supports it. so the sulution are (1) change libvirt-java to support it, and make it released in the next version. Maybe Wido can help us. (2) call virsh command line.
