No Default switch Server 2016 Hyper V

    Question

  • After installing Hyper V on my test Data Center 2016 server. I noticed that the default switch never appeared. Is this something new in Server 2016. On Windows 10 the default switch appears after adding Hyper V.

  • That's correct, Server 2016 does not have a default (NAT) switch, it only exists in Windows 10 (desktop) hyper-v

  • Thank you Dave. Is there anyway to replicate the default switch. My goal is to have my vm access the internet on the same subnet as my host.

  • When you installed the Hyper-V role the host OS was moved to a special VM in the parent partition and a new external vSwitch was created with checkbox checked for allow management OS to share. Any new VMs you create can also use this same vSwitch or you can optionally create a new external vSwitch (assuming you have multiple physical adapters)

    When you create a new external vSwitch the internet protocols are removed and the Hyper-V Extensible Switch protocol is added turning that physical port into a multi-port virtual switch.
