Hi Lluís, Thanks for rebasing. Unfortunately I still hit the hang on shutdown with the simple trace backend. Steps to reproduce: $ ./configure --target-list=x86_64-softmmu --enable-trace-backend=simple $ make $ cat my-events bdrv_open_common $ x86_64-softmmu/qemu-system-x86_64 \ -enable-kvm -m 1024 \ -trace events=my-events \ -drive if=virtio,cache=none,file=test.img Ctrl-Alt-2 (qemu) quit ...hang... Please let me know if you are able to reproduce it. qemu.git/master does not behave this way. Stefan
