[Qemu-devel] [PATCH 0/4] Reduce down time during migration without shared storage |

This series of patches reduce the down time of the guest during a migration
without shared storage. It does that by start transfer dirty blocks in the
iterative phase. In the current code transferring of dirty blocks begins only
during the full phase while the guest is suspended. Therefore the guest will
be suspended linear to the amount of data that was written to disk during
migration.
