Feed: System Center Virtual Machine Manager
Looks like we have a new issue in System Center Virtual Machine Manager where adding a host that has more than 16 processors may crash the server with the following error:
System.InvalidOperationException: Nullable object must have a value.
at System.Nullable`1.get_Value() at Microsoft.VirtualManager.Engine.Adhc.WindowsHostDataProperties.GetProcessorData() at Microsoft.VirtualManager.Engine.Adhc.WindowsHostDataProperties.PopulateProperties()
Fortunately there are a couple different workarounds you can use to get around the issue. To read more about the issue and the workarounds see http://blogs.technet.com/m2/archive/2009/02/09/issues-with-adding-a-host-to-vmm-when-the-computer-has-more-than-16-processors.aspx.
