Hello all
We have migrated 50 or so standalone 2008 and 2008R2 guests to our new 2012 Hyper V platform.
We have some 2008R2 guests which are running on top of Hyper V 2008 (not R2). These run fine and can be mounted on a Windows 2008 R2 Hyper V box.
However when they are mounted on a Windows 2012 server, we can't log into them, the error is the usual 'unknown password'. They boot OK and the Hyper V integration works.
My 'guess'' would be that something has gone wrong because these are 2008 R2 guests which were originally running on 2008 Hyper V.
Any ideas anyone?
