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.

Comment 1 John Snow 2016-06-07 22:55:39 UTC 
Tested with Fedora 24 Beta Workstation for the guest.

Upstream AHCI ATAPI and IDE ATAPI behavior:

After eject, the media is still present, but tray-open is true. This is the expected behavior.

Also verified with scsi-cd using virtio-scsi-pci device as above.


It is *not expected* that the media (iso) will be absent from query-block when using a tray-model CDROM device after an eject. In much the same way that when you eject a CDROM in real life if you do not also remove the media, closing the tray will re-mount the same CDROM.

Removing the media such that it does not appear in query-block requires the use of the medium-remove command OR the legacy "eject" command.

Tray-open bug appears to have been fixed (at least) as of 2.6.0
Comment 3 Yumei Huang 2016-09-10 08:40:04 UTC 
Verify:
qemu-kvm-rhev-2.6.0-23.el7
kernel-3.10.0-497.el7.x86_64

Boot guest with scsi-cd, and eject the cdrom in the guest. The media is present and the tray-open is true.
