VxRail Manager uses the time that is set on ESXi host number 1 (regardless of whether the time is correct or not). You can also configure VMs to sync with ESXi host time. In vSphere ESXi 7.0 U3 and later versions, configuration files for NTP and PTP (/etc/ntp.conf and /etc/ptp.conf) can no longer be edited directly as they are read-only and changes do not persist after reboot. The esxcli system ntp command has to be used instead.
Hello and welcome.
This is Herman from VS Ray support team. And today I am going to show you how to set up an ESXI server as NTP server for VMS. For the first step, we are going to configure the ESXI host to synchronize with a reliable NTP server to accomplish it on this center.
Look for your cluster, select the host you want to configure, click on configure then on the menu, look for system thank configuration. Um On the right panel, you can set your NTP server or the 10 configuration most appropriate for your environment. For more information about this task, you can check the following VMWARE KB.
On the next step, we are going to configure the virtual machine to synchronize the time with the ex server, right? Click on your VM, edit settings VM options, then expand VMWARE tools and then in synchronized time with host, we are going to check this box.
You can click on the information button to get more information about the options that you have to synchronize the time with your ESXI host. Now that your VM is configured to synchronize time with your ESXI host, it's time to check if the configuration has taken effect.
The VM will take time from the ESXI that is hosting it to check the time, open your operating system and check the clock. Be aware that the time zone configuration will affect the hours showed on the operating system. Now, on the host, we can see that the time is synchronized. So this is how to set up ESXI as NTP server for VM. Si Hope you have enjoyed.
Thank you for your time and see you soon.
