We have recently setup a Windows Server 2012 R2 environment, Hyper-V and Clustering.
Our existing environment is Windows server 2008 R2 / Hyper-V and Clustering.
We are experimenting with migrating VM’s from the old cluster to the new cluster, either using the cluster migration wizard or simply exporting VM’s / re importing VM’s
We are experiencing issues with Windows Server 2003 R2 virtual machines, we always end up with 2 unknown device drivers in the device manager, both are stating they are on the Hyper-V Virtual Machine bus, we have installed the integration services on the VM’s, we have even on the existing ones removed any mention of the Integration servers from the registry and completing a fresh install but they still show up as unknown. The strange thing is the device status is working properly, the VM functions correctly but I’m not happy going forward into production with unknown device drivers.
Windows 2008 guests are fine it’s only Windows 2003 guests, we still need to run a number of these legacy servers so upgrading the VM’s not an option.
Has anyone else come across the issue / fixed this issue?
Any advice?
