Description Sibiao Luo 2012-12-24 10:44:37 UTC 
Description of problem:
tray-open should be 1 after ejects the CD-ROM for virtio-scsi device, there is a existing bug 771610(bug 871321) for IDE device, I think the virtio-scsi also should fix this issue.

Version-Release number of selected component (if applicable):
host info:
# uname -r && rpm -q qemu-kvm
2.6.32-348.el6.x86_64
qemu-kvm-0.12.1.2-2.348.el6.x86_64
guest info:
# uname -r
2.6.32-348.el6.x86_64

How reproducible:
always

Steps to Reproduce:
1.boot a guest with a virtio-scsi cdrom device.
eg:...-drive file=/mnt/en_windows_7_ultimate_with_sp1_x64_dvd_618240.iso,if=none,id=drive-cd-disk,media=cdrom,format=raw,cache=none,werror=stop,rerror=stop -device virtio-scsi-pci,bus=pci.0,addr=0x6,id=scsi0 -device scsi-cd,drive=drive-cd-disk,bus=scsi0.0,id=scsi_cd
2.check the block info:
(qemu) info block
drive-virtio-disk: removable=0 io-status=ok file=/mnt/RHEL6.4-20121212.1-Server-x86_64.raw ro=0 drv=raw encrypted=0
drive-cd-disk: removable=1 locked=0 tray-open=0 io-status=ok file=/mnt/en_windows_7_ultimate_with_sp1_x64_dvd_618240.iso ro=1 drv=raw encrypted=0
3.eject the cdrom.
-in monitor:
(qemu) eject drive-cd-disk
-in guest:
] eject -r /dev/sr1
4.check the block info:
  
Actual results:
after step 4,
-in monitor:
(qemu) info block
drive-virtio-disk: removable=0 io-status=ok file=/mnt/RHEL6.4-20121212.1-Server-x86_64.raw ro=0 drv=raw encrypted=0
drive-cd-disk: removable=1 locked=0 tray-open=0 io-status=ok [not inserted]
-in guest:
(qemu) info block
drive-virtio-disk: removable=0 io-status=ok file=/mnt/RHEL6.4-20121212.1-Server-x86_64.raw ro=0 drv=raw encrypted=0
drive-cd-disk: removable=1 locked=0 tray-open=0 io-status=ok file=/mnt/en_windows_7_ultimate_with_sp1_x64_dvd_618240.iso ro=1 drv=raw encrypted=0

Expected results:
The tray-open value should be 1 after eject it.(Should have same behaviour with host).

Additional info:
Comment 2 Sibiao Luo 2012-12-24 11:09:56 UTC 
BTW, both the pass-through SCSI CD-ROM and emulated SCSI CD-ROM can hit it.

I also tried the qemu-kvm-0.12.1.2-2.295.el6.x86_64, it have no such issue.
host info:
# uname -r && rpm -q qemu-kvm
2.6.32-348.el6.x86_64
qemu-kvm-0.12.1.2-2.295.el6.x86_64

Results:
(qemu) info block
drive-virtio-disk: removable=0 io-status=ok file=/mnt/RHEL6.4-20121212.1-Server-x86_64.raw ro=0 drv=raw encrypted=0
drive-cd-disk: removable=1 locked=0 tray-open=0 io-status=ok file=/mnt/en_windows_7_ultimate_with_sp1_x64_dvd_618240.iso ro=1 drv=raw encrypted=0 <------tray-open=0
ide1-cd0: removable=1 locked=0 tray-open=0 io-status=ok [not inserted]
floppy0: removable=1 locked=0 tray-open=0 [not inserted]
sd0: removable=1 locked=0 tray-open=0 [not inserted]
(qemu) eject drive-cd-disk
(qemu) info block
drive-virtio-disk: removable=0 io-status=ok file=/mnt/RHEL6.4-20121212.1-Server-x86_64.raw ro=0 drv=raw encrypted=0
drive-cd-disk: removable=1 locked=0 tray-open=1 io-status=ok [not inserted] <------tray-open=1
ide1-cd0: removable=1 locked=0 tray-open=0 io-status=ok [not inserted]
floppy0: removable=1 locked=0 tray-open=0 [not inserted]
sd0: removable=1 locked=0 tray-open=0 [not inserted]

So, this issue is regression bug, I will make 'Regression' keywords.

Best Regards.

The patch has an unwanted side effect: QMP event DEVICE_TRAY_MOVED gets emitted on shutdown.  Reproducer:

Everything seems fine to me now, but maybe I'm missing something (or just testing the wrong thing...).

Do you use the rhel7 or fedora guest ? As i saw your got the locked event when you do first eject.

It still hit for me with the eject from guest.

Comment 22 Hanna Czenczek 2015-02-02 23:38:17 UTC 
Hi Sluo,

Hm, I cannot reproduce the issue.

I'm testing qemu-kvm 0.12.1.2-2.451.el6 on a Fedora 21 host:

$ git log -1 --oneline | cat
fd8dcf2 Update to qemu-kvm-0.12.1.2-2.451.el6
$ uname -r
3.18.3-201.fc21.x86_64

My guest is CentOS 6.6 minimal (the issue does not appear with Arch Linux either).

$ x86_64-softmmu/qemu-system-x86_64 -enable-kvm -m 512 -drive if=ide,file=centos66.qcow2,cache=none -drive file=CentOS-6.6-x86_64-minimal.iso,if=none,id=drive-cd-disk,media=cdrom,format=raw,cache=none,werror=stop,rerror=stop -device virtio-scsi-pci,bus=pci.0,addr=0x9,id=scsi1 -device scsi-cd,drive=drive-cd-disk,bus=scsi1.0,id=scsi_cd -qmp stdio

... {... "device": "drive-cd-disk", ... "inserted": {... "file": "CentOS-6.6-x86_64-minimal.iso"}, "tray-open": false ...} ...

What looks interesting about your output to me is that first you receive two DEVICE_TRAY_MOVED events, one for the drive being opened and one for it being closed again. But those don't appear at the same time (which would indicate that qemu is misbehaving) but nearly two seconds after each other. Thus, it looks to me like the guest is deliberately closing the tray again after it has been opened.

I don't know an easy way of querying the tray status from inside the guest, though. Could you try to the following sequence?

$ eject /dev/sr1
$ sleep 5
$ eject -T /dev/sr1

If the second eject command does provoke a QMP event about the tray being opened, this would show that the guest is actually aware that the drive has been closed after the first eject command.

If that is the case, I can't think of anything but that it's actually the guest which deliberately closes the drive for some reason or another after it has been opened.

Thank you!

Comment 28 Hanna Czenczek 2015-02-09 15:35:07 UTC 
Hi Sluo,

Using the following command line:

$ /usr/libexec/qemu-kvm -enable-kvm -m 4096 -hda /home/RHEL-Server-6.6-64bit.raw -vnc :42 -drive file=/home/my-cdrom.iso,format=raw,if=none,id=drive-cd-disk,media=cdrom,cache=none,werror=stop,rerror=stop -device virtio-scsi-pci,bus=pci.0,addr=0x9,id=scsi1 -device scsi-cd,drive=drive-cd-disk,bus=scsi1.0,id=scsi_cd -qmp stdio

I cannot reproduce the issue on the command line alone (without having logged in in the GUI). Having logged in in Gnome, however, I can reproduce the issue (both when ejecting from the GUI and from the command line). So I think Gnome is at fault here.

Can you confirm that?


Thanks again,

Max

Correct.

Cool, good catch. I also can't hit it without logging in GUI.

Yes, hit it for me if logging in GUI.

Hi,

I think in conclusion we can say that the issue does not appear with all guests, and at least with one of the two guests where I could reproduce it (but maybe this applies to both after all) the issue appears only after having used the GUI login.

Therefore, it appears to me that qemu is not causing the issue but the guest itself is deliberately closing the tray for some reason.

Thus, closing as NOTABUG. If there are objections, feel free to comment and/or reopen the bug.


Once again, thank you Sluo for providing me with the means to investigate the issue.

Max

On second thought, this is not NOTABUG. Instead, it was just difficult to verify because the guest kept closing the tray pretty much immediately after it had been opened. Changing resolution from NOTABUG to WORKSFORME.
