I am talking about the equivalent of a tcp migration as defined per the
qemu/kvm migrate command done via the qemu monitor
This is taken care of by the migration protocol. Essentially what happens is
that you run a command like:
# virsh migrate --live guest qemu+tls://dest.example.org/system
And in the background, virsh connects to both the local, "source" machine, and
the remote "destination" machine. It then transfers the XML from the source to
the dest, starts up the "container" on the dest with the -incoming command-line
arg, and then does the migration.
The short of it is that yes, libvirt takes care of all of this behind the scenes.
