When I shutdown guest I get a list of messages in form: calcru: runtime went backwards from 478058 usec to 241721 usec for pid 239 (dhclient) The list includes various usec numbers and at least the following process names: sshd, syslogd, pflogd, devd, dhclient, pagezero, vmdaemon, sctp_iterator, fdc0, cam, geom, init, kernel How do I fix this (clock synchronization?) problem? I downloaded FreeBSD Hyper-V image and run VM in a diff mode. If I remember correctly I did not install anything special on the guest to support Hyper-V. I assumed that if Hyper-V image is provided it must have what's necessary. Thank you
