I have tried qith qemu-2.0.0 and the problem still exists there. Triaging old bug tickets... can you still reproduce this issue with the latest version of QEMU? Or could we close this ticket nowadays? I am unable to reproduce this with qemu 2.11.0 OK, thanks for checking again! So I'm closing this ticket now.
