It's specifically for helping with controlling and administration of virtual machine cluster sets/grouping. It's not used for SQL Server at all and isn't needed for typical cluster functionality. It's safe to remove and sounds like it wasn't setup properly in the first place as it lacks an address or other such resource to come online in the other subnet.
You can see more information about the resource along with the dll that implements the functionality and note that it's part of the virtual machine infrastructure (hyper-v):
DisplayName : Virtual Machine Cluster WMI Provider
DllName : vmclusres.dll
