It turns out that it's unconditionally clobbered in XenServer too. https://github.com/xapi-project/xen-api/blob/53d2e8cdff76ca6805c7018948a9c414b9ac7c72/ocaml/xenopsd/scripts/qemu-wrapper#L146 Not that I'm surprised - this falls squarely into guest-physmap mess which is broken in several well-documented ways already. ~Andrew
