My initial implementation idea is to have a pair of systemd units.
I need to make sure that the Xen unit does the right thing for the older instance types with an emulated TSC timer. Also, I believe the feature we actually want to test for is "invariant_tsc" or "nonstop_tsc" instead of just "constant_tsc", which may require a systemd patch. |

What I'd like:
I would like the clock source (/sys/devices/system/clocksource/clocksource0/current_clocksource) to be defaulted on boot per the guidance at https://repost.aws/knowledge-center/manage-ec2-linux-clock-source
Any alternatives you've considered:
