Pending signals (SIGIO and SIGALRM) never seem to be dequeued so that I never kvm_guest_enter()...it appears that only the dynticks alarm_timer gets enabled which only handles SIGALRM, while the rtc alarm_timer which handles SIGIO does not. I have tried to make sure both are enabled, but I still have perpetual pending signals...is this possible??
