Manual migration to file and restore from it, was tested manually and worked fine, migration-test from 'make check' is ok as well. It's probably due broken to "echo foo | $QEMU" There is another issue with -nodefaults option leading to indefinite timeout even if --preconfig wasn't used. I've just posted fix for that so that it won't be masked out by Michal/Daniel's fix. But I've run iotests and -nodefaults fix doesn't affect outcome of the tests (the same 4 failures). > > Max >
