Symptoms

When creating a virtual switch using System Center 2012 Virtual Machine Manager SP1 on a Windows Server 2012 Hyper-V host with a static IP, the static IP information is not present on the virtual switch.

Cause

This issue can occur if a virtual network adapter is not created on the switch, or if the virtual network adapter doesn't have the setting This virtual network adapter inherits settings from the physical management adapter enabled.

Resolution

When creating a virtual switch on a Hyper-V host, if you want the Network Interface Card (NIC) to send management information to Virtual Machine Manager, you need to create a management Virtual Network Interface Card (VNIC) adapter. This VNIC needs to be connected to a virtual machine network that doesn't have isolation enabled. If a VNIC isn't created, communication will only be allowed through the virtual machines that are connected.

If you want the static IP transferred to the virtual switch in Hyper-V, you need to check the setting This virtual network adapter inherits settings from the physical management adapter when creating the VNIC, otherwise it will obtain a DHCP address.
