Stefano,

We can steadily reproduce this S/R issue with Xen #18560 & ioemu-remote(c/s 0f3d6384d1b3d96476f78950b14040f9c1c63375).

Our test has no special operation, just "live-migrate a hvm guest on local host" or "save a hvm guest and then restore it". I attached a guest config with this email, which is using qcow image (using real image also can meet same failure).
