On a Windows Server 2012 R2 or Windows Server 2012 Hyper-V host, the following Microsoft-Windows-Hyper-V-Integration-KVPExchange event ID 4096 is logged:
Log Name : Microsoft-Windows-Hyper-V-Integration/Admin
Event ID: 4096
Message: ‘VM Name’: The Data Exchange integration service is either not enabled, not running or not initialized. (Virtual machine ID <VM GUID>)
This Error event may be logged when a virtual machine (VM) saves, starts or stops, and there is a concurrent request to retrieve a KVP item, such as the IP address or the system version.
Although this event is logged, the error causes no harm to the Hyper-V host. Typically, event ID 4096 is not logged regularly. Therefore, you can safely ignore it because KVP items can be retrieved after a VM starts. If you do see this event logged regularly, it may indicate another problem. In that, we recommend that you contact Microsoft Support.
