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. -- You are receiving this mail because: You are watching the assignee of the bug.
