Windows Server 2019 Preview Build 17623 Hyper-V guest virtual machine network issue

Hello,

I resolved the issue, but I don't no if it was initially my mistake or this is a but. I explain: in short, when I created with Hyper-V Manager from my Windows 10 machine the virtual switch the system doesn't bound the virtual ethernet created with the physical network adapter, so the virtual ethernet had an address like 169.256.xxx.xxx and it was impossible form the guest to communicate with an external network.

First, I tried to give an address of my network to the virtual adapter, but it not worked; after this I used the following powershell command to bound the physical and virtual network:

Set-VMSwitch -Name "External" -NetAdapterNme "Ethernet 2"

where "External" was the vswitch name while the "Ethernet 2" was the physical; to obtain the name of the latter I simply used the powershell command:

Get-NetAdapter

Now I have 2 tests to do to understand better if this is an issue: try to use powershell to create the external vswitch, using the cmdlet New-VMSwitch ("set" cmdlet worked, I don't know if "new" is working, seen the behavior of the user interface to create the external vswitch).

The second test is to not assign an ip to the external vswitch, but let the user interface create it with the issue and then give the set command, to see if the vswitch take the ip address of the physical nic.

If some  "softies" can say something about I'd like to hear.
