Hello, I am running an OpenBSD 6.6 VMM server with a few virtual machines also running 6.6 and noticed that one of them which is running Dovecot 2.3.9 package outputs the following warning every few 10-15 seconds: dovecot: imap: Warning: Time jumped forwards 28.294585 seconds It looks like there is a time issue on that VM although I am running the default ntpd of OpenBSD 6.6 and I have added the following parameter into my /etc/sysctl.conf on that VM: kern.timecounter.hardware=tsc Is there anything else I can do to avoid this time issue in my VM? Best regards, Mabi
The clocks are basically broken on vmm. The pvclock stuff is definitely an improvement, but it's still not there. There's still a ways to go before we have proper, reasonably accurate clocks for vmm guests.
