In the output you provided, SLB01-LTM-1 is unable to contact the NTP server 3.9.0.1 (or ntpd has only just been started/restarted). .INIT. means it has sent an ntp packet, and is still waiting for a response. It hasn't had any replies (reach is 0). Can you ping 3.9.0.1 from LTM-1 ?

 

SLB01-LTM-2 is in time sync (the * next to 3.9.0.1 shows that it is in sync), with a stratum 1 time source that claims to be a GPS based clock, and there is no packet loss (reach=0377 octal) to that device.

 

The output also indicates that your viprion vcmp host (127.3.0.x) is not configured with an NTP source. I suggest you fix that, then your guests can simply sync to that.
