I am assuming you are using either LXC or KVM, right? I do not use those hypervisors, have you executed all of the required configurations to enable live migrations?
If you have already deleted the file “/etc/libvirt/qemu/i-2-28-VM.xml” and tried the migration again, and it did not work. How is your Java debugging skills? I would suggest you to debug the migration workflow, there might be a hidden exception there.
