FWIW Fedora 33 started using > LTO by default, but it was disabled for the qemu package. Hmm, the first looks like a problem. I'm wondering why it happens on f33 only, not f32. LTO could explain that (optimizing away symbols used by modules but not main qemu), but with that already turned off I have no clue offhand. The second is sort-of expected, this comes from s390x not supporting usb. I have a pending patch to silence those warnings when qemu tries to load all available modules (for introspection, to make sure the qom object list is complete). take care, Gerd
