I am starting QEMU with the options below and explicitly set iothread->ctx to NULL. Is that ok as a testcase or should I reduce my open files limit to produce the error? qemu --enable-kvm -smp 2 -m 1024 -object iothread,id=iothread0 -drive file=archipelago:fedora_stable -vnc 0.0.0.0:0 -qmp tcp:127.0.0.1:8888,server,nowait No error message, at least the propagated one, fails silently.
