vCenter Server - Host Profiles - set NTP

Setting your host with NTP services using host profiles requires a few changes to be made in different settings on host profiles.

Solution:

Edit the host profile

• Lets first set the NTP servers:
• General system settings -> Date and Time configuration
• Click Date and time configuration
• Time settings - "Configure a fixed NTP configuration"
• List of time servers - add server IP address or FQDN for NTP servers.  Use comma to list multiple servers
• Now lets enable the NTP service:
• Security and services -> Services configuration -> Services configuration
• Select NTPD (make sure this is enabled)
• On service verify the dropdown box is set to "Establish a fixed service configuration"
• Policy that dictates how the service will be handled - type "on"
• Now lets set the firewall rule:
• Security and services -> Firewall configuration ->  Firewall configuration -> Ruleset Configuration
• Select ntpClient (make sure this is enabled)
• Verify dropdown "Specify the configuration of a fixed ruleset.
• Check the box for enabled  on "Flag indication where ruleset should be enabled"
• Check the box for enabled on "Flag indication where ruleset should allow all ip addresses"  (this is self explanatory)
