VMM cannot add a virtual network adapter without a logical switch. Do one of the following: 
    - Complete the current host profile without defining any virtual network adapter configuration.
    - Cancel the current host profile, create a logical switch, ensure that it contains at least one uplink port profile, and then create or edit the host profile again.
