RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Red Hat Product Errata RHBA-2012:0746 0 normal SHIPPED_LIVE qemu-kvm bug fix and enhancement update 2012-06-19 19:31:48 UTC

Description daiwei 2012-03-14 08:57:30 UTC 
Description of problem:

Boot guest with a virtio-scsi CD-ROM,then eject CD-ROM in guest system.Check tray status in qemu monitor,tray-open's value still be 0.When tray is open,tray-open's value should be 1.

Version-Release number of selected component (if applicable):
# uname -r;rpm -q qemu-kvm
2.6.32-250.el6.x86_64
qemu-kvm-0.12.1.2-2.241.el6.x86_64

How reproducible:
100%

Steps to Reproduce:
1.Boot guest with emulated virtio-scsi CD-ROM

/usr/libexec/qemu-kvm -M rhel6.3.0 -enable-kvm -name RHEL-Server-6.3-64 -smp 2 -m 4G -uuid 4bbfae8f-0d08-41ad-926a-c7a7568d50f7 -boot menu=on -drive file=/home/rhel6.3-64.raw,if=none,id=drive-virtio-disk0,format=raw,cache=none,media=disk,werror=stop,rerror=stop -device virtio-scsi-pci,id=virtio-blk-pci0,bus=pci.0,addr=0x5 -device scsi-hd,drive=drive-virtio-disk0,logical_block_size=512,physical_block_size=512,scsi-id=0,lun=0,bootindex=1 -netdev tap,id=hostnet0,vhost=on,script=/etc/qemu-ifup -device virtio-net-pci,netdev=hostnet0,id=net0,mac=44:37:E6:5E:A3:F2,bus=pci.0,addr=0x4,id=net0 -vnc :1 -vga std -balloon none -monitor stdio -usb -usbdevice tablet -drive file=/home/RHEL6.3-20120304.n.0-Server-x86_64-DVD1.iso,if=none,id=cdrom1 -device virtio-scsi-pci,id=cdrom -device scsi-cd,drive=cdrom1,scsi-id=0,lun=0 -nodefconfig -nodefaults

2.Check CD-ROM status in qemu monitor

3.eject CD-ROM in guest system

#eject /dev/sr0

4.Check CD-ROM status in qemu monitor again
  
Actual results:

After step 4, tray-open's value still be 0 

Expected results:

 tray-open's value should change to 1.


Additional info:

Passthrough virtio-scsi CD-ROM also has this issue.
Comment 2 Paolo Bonzini 2012-03-16 12:28:13 UTC 
Passthrough virtio-scsi CD-ROM is not able to sense the tray state.  Looking into it for scsi-cd CD-ROM.
Comment 3 Paolo Bonzini 2012-03-16 16:50:40 UTC 
This is due to autoclose.  It works if you do "echo 0 > /proc/sys/dev/cdrom/autoclose".  Leaving it open to investigate how it works on real CDs, but since "change" works I'm lowering the priority.
Comment 7 langfang 2012-04-06 06:46:02 UTC 
verify this issue with two senario

senaro 1)
version:
# uname -r
2.6.32-257.el6.x86_64
# rpm -q qemu-kvm
qemu-kvm-0.12.1.2-2.262.el6.x86_64
senario 2)
version:
# uname -r
2.6.32-257.el6.x86_64
# rpm -q qemu-kvm
qemu-kvm-0.12.1.2-2.265.el6.x86_64
steps:
1.boot a guest
/usr/libexec/qemu-kvm -m 2G -smp 1 -cpu Penryn,+x2apic, -usbdevice tablet -drive file=/mnt/RHEL-Server-6.3-64-virtio.qcow2-newinstall5,format=qcow2,if=none,id=drive-ide0-0-0,werror=stop,rerror=stop,cache=none -device virtio-blk-pci,drive=drive-ide0-0-0,id=ide0-0-0,bootindex=2 -netdev tap,id=hostnet0,script=/etc/qemu-ifup -device virtio-net-pci,netdev=hostnet0,mac=00:10:20:2d:31:21,bus=pci.0,addr=0x4,id=net0 -boot order=cdn,once=n,menu=on -uuid 3290efd3-7c9e-44f9-b5f7-af0f3a1b3066 -rtc base=utc,clock=host,driftfix=slew -no-kvm-pit-reinjection -monitor stdio -name rhel6.1 -spice port=1000,disable-ticketing -vga qxl -device virtio-balloon-pci,bus=pci.0,id=balloon0 -device usb-ehci,id=ehci -drive file=/mnt/RHEL6.3-20120313.2-Server-x86_64-DVD1.iso,if=none,id=cdrom1 -device virtio-scsi-pci,id=cdrom -device scsi-cd,drive=cdrom1,scsi-id=0,lun=0 -nodefconfig -nodefaults 

2.Check CD-ROM status in qemu monitor
(qemu) info block
drive-ide0-0-0: removable=0 io-status=ok file=/mnt/RHEL-Server-6.3-64-virtio.qcow2-newinstall5 ro=0 drv=qcow2 encrypted=0
cdrom1: removable=1 locked=0 tray-open=0 io-status=ok file=/mnt/RHEL6.3-20120313.2-Server-x86_64-DVD1.iso ro=0 drv=raw encrypted=0
3.echo 0 >
/proc/sys/dev/cdrom/autoclose  in guest
4.eject CD-ROM in guest system

#eject /dev/sr0

5.Check CD-ROM status in qemu monitor again
(qemu)info block

drive-ide0-0-0: removable=0 io-status=ok file=/mnt/RHEL-Server-6.3-64-virtio.qcow2-newinstall5 ro=0 drv=qcow2 encrypted=0
cdrom1: removable=1 locked=0 tray-open=1 io-status=ok file=/mnt/RHEL6.3-20120313.2-Server-x86_64-DVD1.iso ro=0 drv=raw encrypted=0


so,the stray-open value can be change when eject cdrom.
