I'm not following you here. As far as I understand, post-copy in the 
libvirt driver is triggered on the force complete action and only if (1) 
it's available and (2) nova is configured to allow it, otherwise the 
force complete action for the libvirt driver pauses the VM. The abort 
operation aborts the job in libvirt [1] which I believe triggers a 
rollback [2].
