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.
Yea, usb-storage is icky, the automatic creation of scsi-{hd,cd} devices creates this kind of problems.
With qemu-1.4+ there is a way out: use usb-bot instead (which is almost identical to usb-storage, but is configured like all other scsi host adapters):
qemu -drive if=none,id=usbstick,... \
-device usb-bot,id=bot \
-device scsi-hd,bus=bot.0,drive=usbstick,serial=whatever,...
Kevin, do you see an easy way to fix the block serial issue with usb-storage?
If not I'm tempted to close this WONTFIX and deprecate usb-storage ...

Description of problem: boot a pre-installed vm and with a serial number specified usb storage, but fail to specify the serial number for usb storage correctly with '-drive .... -device usb-storage...serial=xxxx'. I tried two ways (e.g: -drive...serial=xxxx -device usb-storage....; -drive .... -device usb-storage...serial=xxxx) to specify it, just the latter method have problem. Version-Release number of selected component (if applicable): host info: kernel-3.9.0-0.rc4.45.el7.x86_64 qemu-kvm-1.4.0-1.el7.x86_64 seabios-1.7.2-0.2.gita810e4e7.el7.x86_64 guest info: kernel-3.9.0-0.rc4.45.el7.x86_64 How reproducible: 100% Steps to Reproduce: 1.boot a pre-installed vm and with a serial number specified two usb storages with two methods. usb-storage1 -----> serial number: sluo-1 usb-storage2 -----> serial number: sluo-2 2.check the qtree info via HMP monitor. (qemu) info qtree 3.check the serial number info in guest. # scsi_id --whitelist /dev/<dev> Actual results: after step 2, the serial for "usb-storage1" display correctly, but not correctly for "usb-storage2" (qemu) info qtree ... bus: ehci.0 type usb-bus dev: usb-storage, id "usb-storage2" drive = <null> logical_block_size = 512 physical_block_size = 512 min_io_size = 0 opt_io_size = 0 bootindex = -1 discard_granularity = 0 serial = "sluo-2" removable = on port = <null> full-path = on addr 0.5, port 5, speed 480, name QEMU USB MSD, attached bus: usb-storage2.0 type SCSI dev: scsi-disk, id "" drive = storage2 logical_block_size = 512 physical_block_size = 512 min_io_size = 0 opt_io_size = 0 bootindex = -1 discard_granularity = 0 ver = "1.4.0" serial = <null> <----------should "sluo-2" vendor = "QEMU" product = "QEMU HARDDISK" removable = on dpofua = off wwn = 0x0 channel = 0 scsi-id = 0 lun = 0 dev: usb-storage, id "usb-storage1" drive = <null> logical_block_size = 512 physical_block_size = 512 min_io_size = 0 opt_io_size = 0 bootindex = -1 discard_granularity = 0 serial = "sluo-1" removable = on port = <null> full-path = on addr 0.4, port 4, speed 480, name QEMU USB MSD, attached bus: usb-storage1.0 type SCSI dev: scsi-disk, id "" drive = storage1 logical_block_size = 512 physical_block_size = 512 min_io_size = 0 opt_io_size = 0 bootindex = -1 discard_granularity = 0 ver = "1.4.0" serial = "sluo-1" vendor = "QEMU" product = "QEMU HARDDISK" removable = on dpofua = off wwn = 0x0 channel = 0 scsi-id = 0 lun = 0 ... after step 3, the serial for "usb-storage1" display correctly, but not correctly for "usb-storage2". # /usr/lib/udev/scsi_id --whitelist /dev/sdc 0QEMU QEMU HARDDISK storage2 <-------should be sluo-2, not storage2 # /usr/lib/udev/scsi_id --whitelist /dev/sdd 0QEMU QEMU HARDDISK sluo-1 Expected results: Additional info: # /usr/libexec/qemu-kvm -S -M q35 -cpu SandyBridge -enable-kvm -m 4096 -smp 2,sockets=2,cores=1,threads=1 -no-kvm-pit-reinjection -name sluo-test -uuid ed09fa10-6ffe-4811-a42f-0294afcb5a42 -rtc base=localtime,clock=host,driftfix=slew -device virtio-serial-pci,id=virtio-serial0,max_ports=16,vectors=0,bus=pcie.0,addr=0x3 -chardev socket,id=channel1,path=/tmp/helloworld1,server,nowait -device virtserialport,chardev=channel1,name=com.redhat.rhevm.vdsm,bus=virtio-serial0.0,id=port1 -chardev socket,id=channel2,path=/tmp/helloworld2,server,nowait -device virtserialport,chardev=channel2,name=com.redhat.rhevm.vdsm,bus=virtio-serial0.0,id=port2 -drive file=/home/RHEL-Server-7.0-64-scsi.qcow2,if=none,id=drive-system-disk,format=qcow2,cache=none,aio=native,werror=stop,rerror=stop,serial=QEMU-DISK1 -device virtio-scsi-pci,bus=pcie.0,addr=0x4,id=scsi0 -device scsi-hd,bus=scsi0.0,drive=drive-system-disk,id=system-disk,bootindex=1 -netdev tap,id=hostnet0,vhost=off,script=/etc/qemu-ifup -device virtio-net-pci,netdev=hostnet0,id=virtio-net-pci0,mac=08:2e:5f:0a:0d:b1,bus=pcie.0,addr=0x5,bootindex=2 -device virtio-balloon-pci,id=ballooning,bus=pcie.0,addr=0x6 -drive file=/home/my-data-disk.raw,if=none,id=drive-data-disk,format=raw,cache=none,aio=native,werror=stop,rerror=stop -device virtio-scsi-pci,bus=pcie.0,addr=0x7,id=scsi1 -device scsi-hd,bus=scsi1.0,drive=drive-data-disk,id=data-disk,serial=QEMU-DISK2 -readconfig /home/ich9-ehci-uhci.cfg -device usb-tablet,id=input0 -device usb-mouse,id=mouse -chardev spicevmc,name=usbredir,id=usbredirchardev1 -device usb-redir,chardev=usbredirchardev1,id=usbredirdev1,bus=ehci.0,debug=2 -drive file=/home/my-usb-storage1.qcow2,if=none,id=storage1,media=disk,cache=none,format=qcow2,serial=sluo-1 -device usb-storage,drive=storage1,id=usb-storage1,bus=ehci.0,removable=on -drive file=/home/my-usb-storage2.qcow2,if=none,id=storage2,media=disk,cache=none,format=qcow2 -device usb-storage,drive=storage2,id=usb-storage2,bus=ehci.0,removable=on,serial=sluo-2 -global PIIX4_PM.disable_s3=0 -global PIIX4_PM.disable_s4=0 -serial unix:/tmp/ttyS0,server,nowait -qmp tcp:0:4444,server,nowait -k en-us -boot menu=on -vnc :1 -spice disable-ticketing,port=5931 -monitor stdio
