Remove looping over kvm_eat_signal and fold everything into kvm_main_loop_wait. Signed-off-by: Jan Kiszka Signed-off-by: Avi Kivity Hrm, that's disturbing. Unfortunately, the patch is a bit more than just code motion. It does change the number of times the lock is released and makes some minor changes to the code. Nothing obvious that would cause the breakage without digging into it. How did you create your freedos image? I'd like to try and figure out what the problem is here since it may be causing other issues.
