Erratic time issues on VMware based RHEL guests running ntpd/chronyd

Solution Verified - Updated -

Issue

  • Erratic time issues on VMware based RHEL guests running ntpd/chronyd
  • Why is time on my RHEL guests under VMware behaving erratically?
  • Why is time on my RHEL guest under VMware skipping randomly?
  • How can I check if VMware time sync is disabled?
  • VMware has a functionality to enable time synchronization from the host system to VMs. This is typically undesirable and not recommended as it can interfere with ntpd/chronyd. What are the steps to ensure this functionality is disabled?
  • We have some virtual machines (running on VMware ESXi hosts) having problem with time synchronization by using ntpd/chronyd. How do we fix it?
  • VMWare recommends keeping one-off time synchronization enabled. Should we keep it enabled/disabled if ntpd/chronyd is running?

Environment

  • Red Hat Enterprise Linux (RHEL) running as a virtual machine (VM) on a VMware host.
  • ntp
  • chrony
  • NTP (Network Time Protocol)
