I gave this one a quick shot, it ran all fine here. It's a bit of a pity that I still almost need to rely on postcopy-blocktime to get some more info out of the async load process.. but I think it's still OK. One other issue I found though, after applying this patch, QEMU will also allow me to use QMP/HMP "migrate" (rather than "migrate_incoming") command when both postcopy and mapped-ram are enabled, which will ultimately leads to an error: (qemu) info migrate Status: failed (Unable to read from file: Bad file descriptor) What we can do is to disable it for qmp_migrate(), e.g. migrate_prepare() can bail out for outgoing migrations of such setup. Other than that (and the page size issue I raised in the separate email), I think it's ready. Thanks, -- Peter Xu
