When post-copy migration is running in Finish phase we already did everything needed and we're just waiting for all the memory to transfer to the destination. The domain is already running on there at this point. Once all data is transferred (QEMU sends a MIGRATION completed event) we're done. So in this specific post-copy case the source does not need to care about the result of the Finish call as long as QEMU says migration completed. The Finish call to the destination daemon may fail for reasons that do not affect QEMU, e.g., libvirt daemon was restarted there or the libvirt connection broke. Currently we just mark the post-copy migration as failed on the source and keep the domain paused there. But when libvirt daemon is restarted at this point, it will detect migration finished successfully and kill the domain as migrated. It make sense to do this even without having to restart the daemon.

==============================
Libvirt API for virtualization
==============================
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
For some of these hypervisors, it provides a stateful management
daemon which runs on the virtualization host allowing access to the
API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other
languages including Python, Perl, PHP, Go, Java, OCaml, as well as
mappings into object systems such as GObject, CIM and SNMP.
