Can you please explain why dyn or rtc are not the right alarm_timers? My host is linux-2.6.24.

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?? Or is there some corruption somewhere?

How many signal_exits do you see on kvm_stat?
What's your host kernel version?
It wasn't clean if you use dyn tick or rtc clock in qemu. Please post
the command line.
