I recently built a Hyper-V host and installed one guest machine on it. The Host has no issues whatsoever. The Guest, however, has odd time issues that I cannot seem to fix. Below are the specs for the environment:
Host: Dell PowerEdge R720 running Windows Server Datacenter 2012 Core, Hyper-V
In our perimeter network, non-Domain joined, NTP sync from internal NTP server on network (confirmed working)
Guest: Windows Server 2008 R2 Datacenter
Non-Domain joined, NTP sync from internal NTP server on network (confirmed working)
I installed the Guest from a standard 2008 R2 (non-SP1) ISO image from our Volume License. After installation, I modified the policy (gpedit.msc) and pointed Windows Updates to our internal WSUS server (exact same configuration as the Host which updates with
no issues), but I receive the 80072f8f error which all searching indicates there is a time synchronization issue. Time Synchronization in Integration Services is turned off, the Guest and the Host are both synchronizing with the same NTP server (w32tm /config
/manualpeerlist:<IP> /syncfromflags:manual /update) and the Windows Time service is started and set to Automatic start. The Guest will update just fine from Microsoft's update servers, but not our WSUS.
To be clear, this is not isolated to WSUS. This Guest is a web server running BitNami's WAMP stack and using Memcache. Memcache session management fails on the server because it reports the time is off. I have confirmed mltiple times that the Guest time is the exact same (to the second) as every other server in the building and the same time zone. All I can find online are Root Certificate updates (not applicable, but I tried it anyways and still no go) and the Make Sure Your Time is Correct fixes (which it 100% is).
The issue presented itself prior to any configuration of the server beyond Name, IP, and NTP so nothing 3rd party is interfering. All updates available from Microsoft have been installed and the problem persists. I am not sure what else to look at. I have never seen this issue with other Hyper-V hosts, but this is my first 2012 host in the environment. The Host is also fully patched, by the way and has no time issues at all. The Host BIOS is also correct.
Has anyone else seen this or do you have any ideas on how to fix this problem? It is a real showstopper due to the memcache issue. Any help is appreciated, thanks.
