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.

Description Sibiao Luo 2013-10-15 10:14:19 UTC 
Description of problem:
boot up a guest attaching a data disk speicified if=scsi/ide without rerror=stop in cli, the QEMU will quit and core dumped.

Version-Release number of selected component (if applicable):
# uname -r && rpm -q qemu-kvm-rhev
2.6.32-422.el6.x86_64
qemu-kvm-rhev-0.12.1.2-2.412.el6.x86_64
guest info:
2.6.32-422.el6.x86_64

How reproducible:
100%

Steps to Reproduce:
1.boot up a guest attaching a data disk speicified if=scsi/ide without rerror=stop in cli.

Comment 2 Sibiao Luo 2013-10-15 10:17:03 UTC 
If add rerror=stop in cli, QEMU will not core dumped but quit with promt "rerror is not supported by this bus type".
e.g:...-drive file=/mnt/my-data-disk.qcow2,if=scsi,id=drive-data-disk,format=qcow2,cache=none,rerror=stop,werror=stop -device virtio-scsi-pci,bus=pci.0,addr=0x7,id=scsi0 -device scsi-hd,drive=drive-data-disk,id=data-disk,bus=scsi0.0 -k en-us -boot menu=on -spice disable-ticketing,port=5931 -monitor stdio
qemu-kvm: -drive file=/mnt/my-data-disk.qcow2,if=scsi,id=drive-data-disk,format=qcow2,cache=none,rerror=stop,werror=stop: rerror is not supported by this bus type
/etc/qemu-ifdown: could not launch network script

Best regards,

This bug only hit when specified if=scsi. Please refer to bug 1019538 that if specify if=virtio/ide/floppy.
Comment 4 Fam Zheng 2014-04-17 10:54:21 UTC 
-drive file=/mnt/my-data-disk.qcow2,if=scsi,id=drive-data-disk ... -device scsi-hd,drive=drive-data-disk,id=data-disk,bus=scsi0.0

Notice that an interface is already created with if=scsi, then create another device with the drive, is not a valid use case.

Will look into the core dump and replace it with an exit with a friendly error message.
