--- Comment #2 from Paolo Bonzini <bonzini@gnu.org> ---
This is a QEMU bug. It is fixed by commit fc1c4a5 (migration: drop
MADVISE_DONT_NEED for incoming zero pages, 2013-10-24) which will be in QEMU
1.7.
Distros can backport that commit to QEMU 1.6. It cannot be applied alone to
QEMU 1.5 and older.
