Patch for verbose Disk transfer

[Tom Vijlbrief <tom.vijlbrief@xxxxxxxxx>]

A virsh command like:

migrate --live --copy-storage-all Guest qemu+ssh://user@host/system
--persistent --verbose

shows

Migration: [  0 %]

during the storage copy and does not start counting
untill the ram transfer starts

Patch for including the storage copy:
