There are IIRC 3 board models which don't support sd via -device. Also there isn't much documentation that would guide us how to use -device instead of -drive for this. Said that, most boards are already converted and have e.g. explicit SD controllers, so many cases would be fixable, but that requires some deep knowledge of qemu. -- libvir-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/libvir-list
