Hi, As I understand, OSes running inside qemu "have" notion of time: (its date and time works, time(1) command works, etc.). My question is about how qemu manages time. I need to stop and start again this "virtual-time".
I just tried with cpu_disable_ticks() and cpu_enable_ticks(). It seems to work partially: at least now system date and time are out of sync..
