If seconds, maybe the rtc would be best. All sorts of timeouts, from a few miliseconds to seconds. The problematic ones are the longer timeouts, which wait for I/O stuff like disk reads complete. The stuff with smaller timeouts (like waiting for AHCI link become ready) tend to finish instantly in kvm. cheers, Gerd -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
