Hi,
I tried these patches with qemu 2.5.0 on Gentoo and libvirt. I get the
following error:
Error starting domain: internal error: early end of file from monitor:
possible problem:
2015-12-22T21:51:20.659520Z qemu-system-x86_64: -input-linux
/dev/input/by-path/pci-0000:00:14.0-usb-0:12:1.0-event-kbd,grab-all=on:
Could not open '/dev/input/by-path/pci-0000:00:14.0-usb-0:12:1.0-event-kbd'
I also tried setting /dev/input/event9 to permissions of 666 to see if it
was a permission error, but the same thing happened. Any help would be
appreciated.
The way I pass it is with this:
<qemu:commandline>
<qemu:arg value='-input-linux'/>
<qemu:arg
value='/dev/input/by-path/pci-0000:00:14.0-usb-0:12:1.0-event-kbd,grab-all=on'/>
<qemu:arg value='-input-linux'/>
<qemu:arg
value='/dev/input/by-path/pci-0000:00:14.0-usb-0:12:1.1-event-mouse'/>
<qemu:arg value='-input-linux'/>
<qemu:arg
value='/dev/input/by-path/pci-0000:00:14.0-usb-0:12:1.2-event-joystick'/>
</qemu:commandline>
Is there a way around this error?
Thanks,
Jon
