+Changing CD ROM medium sometimes fails with 'Tray of device is not open'
+Description of problem:
+QEMU reports that a CD ROM tray is not open when exchanging media:
+`unable to execute QEMU command 'blockdev-remove-medium': Tray of device 'ide0-1-0' is not open`
+
+We see the issue in upstream libvirt integration tests. However, this issue is a race and the reproducibility rate is <15%.
+Steps to reproduce:
+On the high level this is what we do:
+1. eject medium that the machine was started with
+2. insert a different medium into the CD ROM
+
+Translating the above to QEMU QMP commands this is what the test exercises:
+1. blockdev-open-tray
+2. blockdev-remove-medium
+3. blockdev-del
+4. blockdev-close-tray
+5. blockdev-open-tray
+6. blockdev-remove-medium
+7. blockdev-add
+8. blockdev-insert-medium <<< This is where the test fails
+9. blockdev-close-tray
+Additional information:
+I bisected the code (3 times just to be sure since it's a race) and the following commit fell out of it:
+55adb3c45620c31f29978f209e2a44a08d34e2da
+
+I'm attaching QEMU trace events and a bunch of libvirt test logs (good and bad for comparison). If you think of anything else I should provide in order to help with the issue analysis, please let me know what other option should be turned on.[qemu_traces.tar.gz](/uploads/32e48c92efce3484e552df063795af4d/qemu_traces.tar.gz)
