How should this approach be implemented? To me it looks like set_tsc_info should be called only once for a not-yet-active domU, but I'm not familiar with timekeeping. If it can be just called once, and there should be a way to adjust the tolerance value, then XEN_DOMCTL_settscinfo would need to be changed to have subcommands. Olaf
