Microsoft has published a KB article (KB2795043) that explains the following scenarios:

On System Center Virtual Machine Manager, you may experience one of the following symptoms:

  • A Windows Server 2008 R2 SP1 Hyper-V host has a status of Needs Attention in the VMM Console.
  • or

  • Adding a Hyper-V host or cluster fails.

The fix is … to uninstall the WMF 3.0 update (KB2506143).  There’s a bit more to it than that. You also need to reboot the host and then run:

winrm qc

… and then do another reboot of the host.

I know; it’s far from an ideal situation.  But there’s the workaround for you.

  1. Thanks Aidan, this issue has been plaguing us for the last month or so. For us the problem wasn’t that the hosts had “needs attention status”, they all had OK status, but we couldn’t for example connect a vNIC to a vSwitch, this would always fail. Other symptom was that we couldn’t manage vSwitches from VMM. Following the steps in the mentioned KB fixed the problem for us.
