[Qemu-devel] "i8042.c: No controller found" -> OS sees no keyboard if I type "in BIOS"

[Tomasz Chmielewski <mangoo@wpkg.org>]

When I boot the guest and type (just hit any keys) in the VNC window 
before the operating system boots, sometimes, the system loads with no 
keyboard present - as signified in dmesg on guest:


i8042.c: No controller found

As a result, I can't use the keyboard in the VNC window.

If I start qemu process and I don't press any key, I can use the 
keyboard once the operating system boots.


Rebooting the guest doesn't fix the problem, even if I don't touch the 
keyboard before the OS boots any more.
Only stopping the guest and starting a new qemu process fixes the problem.


Anyone else saw it as well? If not, try something like that on your guests:


grep i8042 /var/log/kern*

(or grep "i8042.c: No controller found" /var/log/kern*)


Some more confirmations of this problem in the internet:
