Qemu can do shared-nothing live migration since a long time.

  Migrating a VM by itself is simple.

    Literally 3/4 of the blog post is about how they migrate a VM. With qemu they wouldn't need the iscsi workaround as nbd (both server and client) is rock-solid in qemu. Nor the discard dance since qemu at the source knows what blocks are in use (via bitmap or zero-detection). Also qemu can copy the data up-front so performance stays consistent.

      Interesting, maybe I should read the post more carefully.
