+Cannot create cdrom device with open tray and cache option
+
+When trying to create cdrom device with open tray and either of "cache" or "discard" options specified, I get the following error:
+
+qemu-system-x86_64: -drive if=none,id=drive-ide0-0-0,readonly=on,cache=writeback,discard=unmap,throttling.iops-total=900: Must specify either driver or file
+
+This bug essentially forbids live migration of VMs with open cdrom trays.
+
+I was able to find the same bug at RedHat:
+https://bugzilla.redhat.com/show_bug.cgi?id=1338638
+
+The bug was encountered in versions 2.5 and 2.11.
+
+Hi, versions 2.5 and 2.11 are quite old (though version 2.10 fixed the bug mentioned in the Red Hat BZ, so I think this might be a different bug.)
+
+
+It's not clear at what step this is failing or where you are seeing the error message, so:
+
+1. What is your full command line for QEMU?
+2. Do you see this error message when migrating? If so, what does the destination QEMU command line look like?
+3. Does the problem reproduce on a currently-supported upstream QEMU? (4.1.1, 4.2.0)
+
+[Expired for QEMU because there has been no activity for 60 days.]
