Well, if the Dom0 is keep in sync, the DomU clock should also be in sync, but I'm not sure how often does FreeBSD poll the underlying clock, so I would recommend running ntp even in that case (certainly it's not going to hurt). > Likewise do you know if there is any recommended solution for 9.x (which > is the bulk of our VM's). Apart from ntp/ntpdate, I cannot think of anything else. Backporting the changes from 10 is certainly not going to be easy.
