Red Hat Bugzilla – Bug 711354
Fix and enable enough of SCSI to make usb-storage work
Last modified: 2011-12-06 10:52:13 EST
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
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.
Updating summary to restrict scope as per comment#3.
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?
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+
Updated priority and servity to match bz561414 which depends on this bug.
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.
735018 is a known issue, fix underway. 733010 needs investigation. Looks like a real bug on a quick check.
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.
