I found a tip in VirtualBox helps, and the trick seem to solve the problem. But, I am not sure this is the right solution. The trick is, on OpenSolaris (the host system), to type the command. $ VBoxManage setextradata "My VM name" "VBoxInternal/TM/TSCTiedToExecution" 1 The FreeBSD VMs no more need ntpd to sync the clock.
