03 August, after that, there was a local snpashot built from sources fetched on 17 Aug 2022 22:12:57 +0300 which wasn't affected. > 2.

As I said, I mistakenly changed the OS type not to "FreeBSD Pre-11 versions (32-bit)", but to "FreeBSD 11 (32-bit)". The problem affects only VMs which have Guest OS Version set to "FreeBSD Pre-11 versions (32-bit)" on snapshots built after 31 Aug 2022. Sample outputs from the machine running older snapshot which is not affected: $ sysctl kern.version | head -n1 kern.version=OpenBSD 7.2-beta (GENERIC.MP) #1: Thu Aug 18 15:15:13 MSK 2022 $ sysctl | grep tsc kern.timecounter.hardware=tsc kern.timecounter.choice=i8254(0) acpihpet0(1000) tsc(2000) acpitimer0(1000) machdep.tscfreq=1500017850 machdep.invarianttsc=1 -- With best regards, Pavel Korovin
