When I create a new VM with VM Network assigned I am getting the Error (20408). The same thing will happen when I try to assign VM network to the existing VM. In the case when I am using Hyper-V manager to assign VLAN and to connect VMs everything is workingfine, after that VM needs a refresh in VMM. This issue starts in the beginning of January. Anyone have the same problem and solution?
VMM could not get the specified instance Scvmm_EthernetSwitchPortInternalSettingData.InstanceID="Microsoft:Definition\1f59a509-a6ba-4aba-8504-b29d542d44bb\Default" of class Scvmm_EthernetSwitchPortInternalSettingData on the server HYPERVHOST1.example.ug The operation failed with error HRESULT 0x80338000 The WS-Management service cannot process the request. The class Scvmm_EthernetSwitchPortInternalSettingData does not exist in the root/virtualization/v2 namespace. Recommended Action Ensure the provider is running, and then try the operation again.
