You've already asked these questions before and got two
sets of answers:

  http://www.redhat.com/archives/libvir-list/2011-May/msg01641.html
  http://www.redhat.com/archives/libvirt-users/2011-May/msg00076.html

To repeat again: the migration transport is in QEMU, so send these
questions to the QEMU mailing list.
