      Hi guys,

      I just finished doing a system migration of the weekend for my client. Migrated them from some very old physical 2003 servers to 2012r2 (2VMS) running on top of Xenserver 7.0 on a Dell R530. S.A.M said that this forum was a good resource for all things XenServer so I just joined today.

      VM1 is AD DS/DNS/DHCP/File server and the second VM is just a secondary domain controller with AD DS/DNS roles. VM1 has all the FSMO roles including PDC emulator. From my understanding the ideal time configuration is for the DC running PDC emulator to get the time from an ntp server, and then the secondary DC & workstations should then sync to the primary DC.

      From what I understand though, when you install the guest tools on the VM, it will always sync to the XenServer's hardware clock and this cannot be disabled like it can on ESXi.

      I wanted to see what you guys would recommend as far as best practices goes in configuring how these VMs/XenServer syncs time. Thanks!

        As far as I am aware that is correct. In the past I've seen people point the Xenserver hosts to the same time server as the "Primary" domain controller is pointing to. This way they are always in sync with the external server.

            @coliver I configurd XEN to pull time from us.pool.ntp.org, and I guess I'll just go into the primary DC and tell W32time to sync with the same server

              That should work fine.

                I'm trying to recall but @JaredBusch has had issues with the US NTP pool. He may be able to comment further. Otherwise this should work fine.
