+If you are able to, it will greatly facilitate bug triage if you attempt

+how to do this.
+
+QEMU generally supports the last two releases advertised on
+https://www.qemu.org/. Problems with distro-packaged versions of QEMU
+older than this should be reported to the distribution instead.
+
+See https://www.qemu.org/contribute/report-a-bug/ for additional
