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 Gerd Hoffmann 2011-06-07 09:46:37 UTC 
Description of problem:
usb-storage depends on scsi (just scsi-bus and scsi-disk to be exact).
scsi is disabled in RHEL-6.1 qemu-kvm.  It must be enabled and
fixed (doesn't build right now).

Version-Release number of selected component (if applicable):
qemu-kvm-0.12.1.2-2.160.el6.x86_64
Comment 3 Gerd Hoffmann 2011-06-07 12:40:32 UTC 
I just need enougth scsi bits to make usb-storage work.
The lsi host adapter can be left disabled.

On QA: autotest support for usb storage has been submitted and merged upstream.
Comment 5 Markus Armbruster 2011-06-08 07:24:24 UTC 
Updating summary to restrict scope as per comment#3.
Comment 6 Markus Armbruster 2011-06-08 07:33:12 UTC 
We better do what we can to limit the test and support matrix.

Can we keep qdev "scsi-generic" disabled?

Can we restrict qdev "scsi-disk" to disks, and keep CD-ROMs disabeled?
Comment 7 Gerd Hoffmann 2011-06-08 08:25:29 UTC 
scsi-generic can be kept disabled.  Can be used in with usb-storage in theory, but I certainly don't feel like testing and supporting that combination.

scsi-disk emulating a cdrom works just fine with usb-storage.  autotest also excercises installations from a virtual usb cdroms, so I'd leave that enabled.

Combined with bz561414, mark qa_ack+
Comment 14 Gerd Hoffmann 2011-06-15 11:06:57 UTC 
Updated priority and servity to match bz561414 which depends on this bug.
Comment 24 Shaolong Hu 2011-09-02 03:27:21 UTC 
Hi Gerd,

During usb device functional test, we have two new bugs about usb-storage:

Bug 733010 - core dump when issue fdisk -l in guest which has two usb-storage attached

Bug 735018 - qemu-kvm will be aborted with core dumped when boot guest has ehci and uhci storage attached simultaneous


Please have a look if they are trouble, thanks.
Comment 25 Gerd Hoffmann 2011-09-02 07:28:00 UTC 
735018 is a known issue, fix underway.
733010 needs investigation.  Looks like a real bug on a quick check.
Comment 26 juzhang 2011-10-09 03:48:59 UTC 
According to comment24,we did usb device functional test,basically works well.
we found two bugs(bz733010 and bz734995),we close this issue and continue track and verify these two bugs.
