Comment 1 Daniel Berrangé 2011-05-04 09:34:56 UTC

Did you reconfigure the Xorg server in the guest to correctly use the 'evdev' device for handling the USB tablet ?  RHEL-5 vintage Xorg does *not* automatically configure input devices correctly and thus always requires manual admin configuration. Without  the admin config steps you'll get crazy mouse movement like you describe.

Only RHEL-6 / Fedora 8+  / Windows  are capable of using a USB tablet without manual config steps.

Comment 2 FuXiangChun 2011-05-05 06:29:16 UTC

add below section to xorg.conf configuration. mouse work well. 

Section "InputDevice"
Identifier "Configured Mouse 0"
# Driver "mouse"
Driver "evdev"
Option "Device" "/dev/input/mice"
Option "Protocol" "ExplorerPS/2"
Option "Emulate3Buttons" "true"
EndSection

Comment 5 FuXiangChun 2011-05-26 01:52:30 UTC

sorry, i am mistake, about Comment2 method, i don't change video card to qxl, if change video card to qxl and start guest --usbdevice tablet option then mouse still randomly move in guest, In order to further investigate this issue i reopen this bug. i tried to used below configuration to reconfigure the Xorg server but still got the same issue. if there is any way to solve it please add comments.

3. can get usb device in guest after guest booted
/sys/devices/pci0000:00/0000:00:01.2/usb1/1-2/1-2:1.0/input:input2/mouse1

Comment 6 Eduardo Habkost 2011-05-30 14:29:39 UTC

Moving to NEW, bugs assigned to virt-maint shouldn't be on ASSIGNED state.

Comment 7 Gerd Hoffmann 2011-06-14 15:22:28 UTC

Tablet config should look like this:

Section "InputDevice"
        Identifier "Tablet"
        Driver "evdev"
        Option "Device" "/dev/input/event2"
        Option "CorePointer" "true"
EndSection
