VM time sync with Dom0
-
Hello.
How to sync time with xcp-ng host? My VM doesn't have Internet access and NTP sync can't work in this case. -
Hi,
Use a NTP server inside your network then
-
@olivierlambert any other suggestions? time sync with guest tools for example?
Our client can't use Internet access at all. -
If you don't have any internet access, you need a common "source of truth" for your time. An internal NTP server will be better than nothing
There's also some devices that could provide relatively consistent time -
@topsecret Another option is to run a hardware network time server which uses an atomic clock. Then point the NTP client for the systems of your client at that hardware time server.
You can choose one of the following hardware time servers:-

For clients which can't have internet at all even for NTP time synchronisation then running a hardware time server is a must for the network. That way all of the clocks will then be in sync with each other.
