Hmm.  Guess the fundamental issue is that libvirt wants to use the 
monitor to set the ticket instead of the command line for security 
reasons.  The qemu monitor doesn't accept commands while the incoming 
migration is running.  We also can't kick the incoming migration via 
monitor, so first setting the ticket then start migration doesn't work 
too.  Correct?
