usb device info screenshot in rhel6 host
root cause: upstream commit a309ee6e0a256f690760abfba44fceaa52a7c2f3 that one fixes a serious issue with xhci though, so simply reverting doesn't cut it. need to dig into xhci, guess we don't do intr endpoint intervals correctly. Re-tested this bug. Start with this version qemu-kvm-1.5.0-1.el7.x86_64 QE found this problem.　Before this version, qemu-kvm don't hit this issue. so I added regression to Keywords Bad patch has been backported to rhel-6. As there is no xhci in rhel6 we can simply revert it there. rhel-7 needs xhci being fixed first. patches posted upstream meanwhile, backport to be done once they are in. patches merged upstream, backport done, patches posted. Fix included in qemu-kvm-1.5.3-10.el7 Reproduce this bug with components: qemu-kvm-1.5.3-4.el7.x86_64 Steps: 1.Boot windows7 64bit guest with 16 usb disks like this: # /usr/libexec/qemu-kvm -M pc-i440fx-rhel7.0.0 -cpu Opteron_G3 -enable-kvm -m 2G -smp 4,sockets=2,cores=2,threads=1 -name usb-test -rtc base=localtime,clock=host,driftfix=slew -drive file=/home/win7-64-virtio.qcow2,if=none,id=drive-system-disk,format=qcow2,cache=none,aio=native,werror=stop,rerror=stop -device ide-hd,bus=ide.0,unit=0,drive=drive-system-disk,id=system-disk,bootindex=1 -qmp tcp:0:4444,server,nowait -k en-us -boot menu=on -vnc :1 -vga std -monitor stdio \ -readconfig /home/ich9.cfg \ -drive file=/home/disk1.qcow2,if=none,id=drive-usb-0-1,media=disk,format=qcow2,aio=native -device usb-storage,drive=drive-usb-0-1,id=usb-0-1,removable=on \ -drive file=/home/disk2.qcow2,if=none,id=drive-usb-0-2,media=disk,format=qcow2,aio=native -device usb-storage,drive=drive-usb-0-2,id=usb-0-2,removable=on \ -drive file=/home/disk3.qcow2,if=none,id=drive-usb-0-3,media=disk,format=qcow2,aio=native -device usb-storage,drive=drive-usb-0-3,id=usb-0-3,removable=on \ -drive file=/home/disk4.qcow2,if=none,id=drive-usb-0-4,media=disk,format=qcow2,aio=native -device usb-storage,drive=drive-usb-0-4,id=usb-0-4,removable=on \ -drive file=/home/disk5.qcow2,if=none,id=drive-usb-0-5,media=disk,format=qcow2,aio=native -device usb-storage,drive=drive-usb-0-5,id=usb-0-5,removable=on \ -drive file=/home/disk6.qcow2,if=none,id=drive-usb-0-6,media=disk,format=qcow2,aio=native -device usb-storage,drive=drive-usb-0-6,id=usb-0-6,removable=on \ -drive file=/home/disk7.qcow2,if=none,id=drive-usb-0-7,media=disk,format=qcow2,aio=native -device usb-storage,drive=drive-usb-0-7,id=usb-0-7,removable=on \ -drive file=/home/disk8.qcow2,if=none,id=drive-usb-0-8,media=disk,format=qcow2,aio=native -device usb-storage,drive=drive-usb-0-8,id=usb-0-8,removable=on \ -drive file=/home/disk9.qcow2,if=none,id=drive-usb-0-9,media=disk,format=qcow2,aio=native -device usb-storage,drive=drive-usb-0-9,id=usb-0-9,removable=on \ -drive file=/home/disk10.qcow2,if=none,id=drive-usb-0-10,media=disk,format=qcow2,aio=native -device usb-storage,drive=drive-usb-0-10,id=usb-0-10,removable=on \ -drive file=/home/disk11.qcow2,if=none,id=drive-usb-0-11,media=disk,format=qcow2,aio=native -device usb-storage,drive=drive-usb-0-11,id=usb-0-11,removable=on \ -drive file=/home/disk12.qcow2,if=none,id=drive-usb-0-12,media=disk,format=qcow2,aio=native -device usb-storage,drive=drive-usb-0-12,id=usb-0-12,removable=on \ -drive file=/home/disk13.qcow2,if=none,id=drive-usb-0-13,media=disk,format=qcow2,aio=native -device usb-storage,drive=drive-usb-0-13,id=usb-0-13,removable=on \ -drive file=/home/disk14.qcow2,if=none,id=drive-usb-0-14,media=disk,format=qcow2,aio=native -device usb-storage,drive=drive-usb-0-14,id=usb-0-14,removable=on \ -drive file=/home/disk15.qcow2,if=none,id=drive-usb-0-15,media=disk,format=qcow2,aio=native -device usb-storage,drive=drive-usb-0-15,id=usb-0-15,removable=on \ -drive file=/home/disk16.qcow2,if=none,id=drive-usb-0-16,media=disk,format=qcow2,aio=native -device usb-storage,drive=drive-usb-0-16,id=usb-0-16,removable=on \ 2.Check via hmp: (qemu) info usb Device 0.1, Port 1, Speed 480 Mb/s, Product QEMU USB MSD Device 0.2, Port 2, Speed 480 Mb/s, Product QEMU USB MSD Device 0.3, Port 3, Speed 480 Mb/s, Product QEMU USB MSD Device 0.4, Port 4, Speed 480 Mb/s, Product QEMU USB MSD Device 0.5, Port 5, Speed 480 Mb/s, Product QEMU USB MSD Device 0.1, Port 6, Speed 12 Mb/s, Product QEMU USB Hub Device 0.2, Port 6.1, Speed 12 Mb/s, Product QEMU USB MSD Device 0.3, Port 6.2, Speed 12 Mb/s, Product QEMU USB MSD Device 0.4, Port 6.3, Speed 12 Mb/s, Product QEMU USB MSD Device 0.5, Port 6.4, Speed 12 Mb/s, Product QEMU USB MSD Device 0.6, Port 6.5, Speed 12 Mb/s, Product QEMU USB MSD Device 0.7, Port 6.6, Speed 12 Mb/s, Product QEMU USB MSD Device 0.8, Port 6.7, Speed 12 Mb/s, Product QEMU USB MSD Device 0.9, Port 6.8, Speed 12 Mb/s, Product QEMU USB Hub Device 0.10, Port 6.8.1, Speed 12 Mb/s, Product QEMU USB MSD Device 0.11, Port 6.8.2, Speed 12 Mb/s, Product QEMU USB MSD Device 0.12, Port 6.8.3, Speed 12 Mb/s, Product QEMU USB MSD Device 0.13, Port 6.8.4, Speed 12 Mb/s, Product QEMU USB MSD 3.Check the usb disks in windows guest: result: there're only 6 usb disks Verify this bug with component: qemu-kvm-1.5.3-10.el7.x86_64 same steps as above Result: from the guest inside, there're 16 usb disks.
