Description

Sometimes keyboard doesn't work in VMs under QEMU/KVM. Everything else works. Rebooting usually fixes the problem, but sometimes I have to reboot twice or thrice.

With beta4 AND master. I'm current.

Please attach a syslog of when it happens. I have also experienced this, it's usually accompanied by PS/2 errors.

Component: System → Drivers/Input/PS2/Keyboard
Platform: x86-64 → All

As expected, PS/2 errors.

ps2: keyboard found
error when KB_SET_KEY_REPEAT_RATE, fd:5
error when KB_SET_KEY_REPEAT_DELAY, fd:5

I've also noticed that when keyboard DOES work, I get a "keyboard hotplug detected" or something like that in the log

In the meantime you can use usb in qemu:

... -usb -device usb-kbd -device usb-tablet ...
