It's interesting to imagine that a virtualization host could present a time service to the guest *userspace*, even when the guest is not otherwise exposed to the internet at large. This could take the form of an NTP server on a private network, or as an implementation of a time source directly usable by ntpd in the guest, for instance as an emulated serial port with synthetic NEMA GPS signal + PPS signal, for instance. _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
