Similar report on the list: https://lists.gnu.org/archive/html/qemu-devel/2018-11/msg03509.html

I'll mention this bug there
Comment 7 Bandan Das 2018-12-04 19:45:53 UTC 
This should be fixed by commit aec5e9c3a94cf8b7920f59bef69a6f426092c4a0.
It's already in qemu/master.
Comment 8 Cole Robinson 2018-12-12 12:50:57 UTC 
3.1.0 GA is built for rawhide now
