Rebooting the guest doesn't fix the problem; only stopping/starting the guest helps (i.e. new kvm process is started). Which is a bit strange - usually, the keyboard is there when I boot: serio: i8042 KBD port at 0x60,0x64 irq 1 serio: i8042 AUX port at 0x60,0x64 irq 12 input: AT Translated Set 2 keyboard as /devices/platform/i8042/serio0/input/input0 The keyboard is not present after I reboot the guest and usually type before Linux is started. It does not happen always. Observed with kvm-83, kvm-84, kvm-85 on multiple KVM hosts (different hardware). Anyone else seeing this? If you're not sure, do something like: grep i8042 /var/log/kern* (or grep "i8042.c: No controller found" /var/log/kern*) -- Tomasz Chmielewski http://wpkg.org
