Attempting to add more than one server to the NTP servers via the GUI (Lifecycle Operations > Settings > Time Settings) results in an invalid /etc/ntp.conf file:
root@vlcmtest [ /etc ]# cat /etc/ntp.conf tinker panic 0 restrict default kod nomodify notrap nopeer noquery restrict 127.0.0.1 restrict -6 ::1 driftfile /var/lib/ntp/drift/ntp.drift server 69.64.225.2,216.229.4.66
NTP does not work on the VMs as a result.
