Symptoms

Cause

This has been seen to occur in the following scenarios:

  1. If there is no default gateway on any of the Network Interface Adapters (NICs) on the Hyper-V hosts that are being clustered.
  2. If VMM services times out attempting to connect to the VmmHelperHost process

Resolution

To resolve this issue, ensure a default gateway is defined on one of the cluster NICs on each node that have a compliant status in VMM on the Hyper-V hosts.

If the problem is not resolved, consider increasing the HelperHostConnectRetryCount from the default of 5 to a larger value such as 10. This will effectively increase the timeout from 10 seconds to 50 seconds.

Warning: Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
