Hi misc, I'm running OpenBSD 6.4 stable on my notebook and wanted to play around with docker within debian VMs.
1 created 3 debian (stretch) VMs (2nd and 3rd are just copies and modified later). I had some trouble getting docker (containerd) running. It was always using 100% CPU and I didn't know, why. Found out it made many "clock_gettime" syscalls and found a thread, that setting the clocksource to "tsc" within the VM would improve performance. And, indeed, setting the clocksource to "tsc" fixes the containerd problem. But the main problem is, that sometimes the "tsc" clocksource is not available within the VM. Until now, only 2 of the 3 debian VMs have the "tsc" clocksource available, if all 3 are running. If I stop one of the 2 VMs that have "tsc" available and restart the one that did not have it, that one *then* has the "tsc" available. But not always. So this looks somehow pretty random to me. So here is an example, when "tsc" is not available root@debian2-vm:~# dmesg | grep tsc [ 0.000000] tsc: Fast TSC calibration failed [ 0.000000] tsc: Unable to calibrate against PIT [ 0.000000] tsc: No reference (HPET/PMTIMER) available [ 0.000000] tsc: Marking TSC unstable due to could not calculate TSC khz root@debian2-vm:~# And here it is (on the same VM after one or more reboots) root@debian2-vm:~# dmesg | grep tsc [ 0.000000] tsc: Fast TSC calibration failed [ 0.000000] tsc: Using PIT calibration value [ 0.000000] tsc: Detected 15521.837 MHz processor [ 1.948708] clocksource: tsc: mask: 0xffffffffffffffff max_cycles: 0x1bf7a091b1e1, max_idle_ns: 881591361965 ns [ 1.948709] clocksource: Switched to clocksource tsc [ 2.797715] clocksource: timekeeping watchdog on CPU0: Marking clocksource 'tsc' as unstable because the skew is too large: [ 2.797716] clocksource: 'tsc' cs_now: 2cd3e49b586 cs_last: 2cbb8a34d2c mask: ffffffffffffffff root@debian2-vm:~# Is this known and possibly fixed in current?
