I'm not sure what you mean - commands for live migration or internals
of how migration works?

Migration:
1. Start QEMU on the destination host with exactly the same
command-line parameters as on the source host plus "-incoming
tcp::1234".
2. Switch to the QEMU monitor on the source host and use the "migrate
tcp:<destination-host>:<destination-port>" command.

To understand how migration works, see migration*.c in the source.
