[Qemu-devel] [PATCH 0/6] Recovery from network failure during Postcopy Migration

[Md Haris Iqbal]

Final Report Link : https://harisphnx.github.io

Usage : Once the network fails, wait for both the sides to error out and go
        into recovery. This can be understood by the error messages printed at
        the terminal.
        Once both the sides are under recovery, the reconnection can be tried.
        First in destination side console, enter the migrate_incoming command
        with the new -r flaga along with the same details as used in the
        beginning.
        Then, same goes for the source side. Use the migrate command with the
        new -r flag and similar details as used in the beginning.
