Description Suqin Huang 2013-01-09 04:42:10 UTC

Description of problem:
usb-tablet doesnt work when boot guest with -M q35

Version-Release number of selected component (if applicable):
qemu-kvm-1.3.0-3.el7.x86_64
seabios-1.7.2-0.2.gita810e4e7.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1. cmd
/usr/libexec/qemu-kvm -nodefaults \
-device ich9-usb-uhci1,id=usb1,bus=pcie.0,addr=0x4 \
-drive file='/home/autotest-devel/client/tests/kvm/images/RHEL-Server-6.4-64-virtio.qcow2',if=none,id=drive-ide0-0-0,media=disk,cache=none,format=qcow2,aio=native \
-device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0 -device virtio-net-pci,netdev=idUMvixC,mac=9a:87:88:89:8a:8b,bus=pcie.0,addr=0x3,id='idMztaHV' -netdev tap,id=idUMvixC,vhost=on,script=/home/autotest-devel/client/virt/scripts/qemu-ifup-switch \
-m 2048 -smp 2,cores=1,threads=1,sockets=2 -cpu 'Opteron_G3' \
-device usb-tablet,id=usb-tablet1,bus=usb1.0,port=1 -vnc :0 -vga cirrus -rtc base=utc,clock=host,driftfix=slew  -boot order=cdn,once=c,menu=off   -no-kvm-pit-reinjection -enable-kvm -monitor stdio  \
-chardev socket,id=serial_id,path=/tmp/serial-shuang,server,nowait -device isa-serial,chardev=serial_id \
-M q35

Comment 2 Hai Huang 2013-01-09 20:28:18 UTC

Please re-assign if this is a Q35 problem (i.e. not an uhci_hcb/usb issue).

Comment 3 Gerd Hoffmann 2013-01-10 06:33:01 UTC

q35 in qemu 1.3 needs the dsdt passed in to work correctly:

"-acpitable file=/path/to/q35-acpi-dsdt.aml"

q35-acpi-dsdt.aml should come with seabios

Note that this is temporary, in qemu 1.4 it will not be needed any more (but wouldn't hurt either).

Comment 4 Suqin Huang 2013-01-11 05:19:19 UTC

it works when adding -acpitable file=/path/to/q35-acpi-dsdt.aml

Comment 5 Gerd Hoffmann 2013-01-11 07:43:43 UTC

Good, closing as upstream then as the upcoming qemu 1.4 should work fine.
