Windows 10: Hyper-V does not allow my VM to the internet

When I was at build 10074 I had Hyper-V working and the Virtual Machine (also at build 10130 but several days before the host upgraded)
had LAN and internet access. After the upgrade to 10130 the VM can see the host on in the Network, but not the internet.


Network adn Sharing on the VM shows "Unidentified Network and Public Network". It shows two connections - Ethernet and Ethernet2. Access type is
"No network access"


Network Connections shows two connections: Ethernet (Microsoft Hyper-V Network Adaptor) and Ethernet2 (also Microsoft Hyper-V Network Adaptor). Right click and display properties for both and they show all items checked except Microsoft Network Adapter Multiplexor Protocol. Status for both is IPv4 no network access, IPv6 no network access, Media Sate Enabled. The picture indicates that they are connected via a cable.


In Hyper-V if I select the Virtual Switch Manager it fails to load and the Vitual Machine Management Service is not available. I can close the Virtual Switch and re-start the Virtual Machine Management service. This of course kills my connection and I have to re-start the VM.


The host has no issues with the network or internet. In the Network Connections for the host there are four connections:


Ethernet (Realtek PCIe GBE Family Ciontroller) with everything checked except Microsoft Network Adapter Multiplexor Protocol adn Hyper-V Extensible Virtual Switch. Icon shows a cable.


Ethernet2 (Microsoft Network Adapter Multiplexor Driver) with nothing checked except Hyper-V Extensible Virtual Switch. Icon shows a cable.


vEthernet (Fir) (Hyper-V Virtual Ethernet Adapter) with everything checked except Microsoft Network Adapter Multiplexor Protocol and Hyper-V Extensible Virtual Switch. Icon shows a cable.


Wi-Fi (Realtek RLT8188CD Wireless LAN 802.1 in PCI-NIC with this comment: This adapter is part of the Network Bridge. The icon shows wireless connection. This has to be connected or the VM has no access at all.


As an aside in Network Connections for the host, the right click closes the dialog and several other program. Clicking on an item displays a horiziontal menu that mimics the right-click menu. These buttons work.


So the question is: how do I get internet on my VM?

Running Windows Phone 8 emulator on remote hyper-v server

I typically do my development in a VM running in a Windows 2012 Hyper-V Server. With the Windows Phone 8 SDK, the emulator runs in the local hyper-v install of the Windows 8 pro. That does not work if the main os is running in a hyper-v already. So my
question is, can you change the default hyper-v server of the Windows Phone SDK to run on a different hyper-v installation (like one running on another computer)?

So for instance, the emulator would run off a my remote hyper-v server instead of the development vm it is installed on? If this capability is not allowed default, could someone (thinking of myself) create a plugin to allow for this configuration of the emulator?
Just looking for some guidance as to how the emulator works.

 

Windows 10 Hyper-V PCI Passthrough

Does anyone know if you can pass a PCI device from the Host machine to a VM? I am using Windows 10 Hyper-V. I am trying to pass a PCI device to a windows 10 VM. Is this possible through the built-in Hyper-V manager in Windows 10. I read somewhere where
Hyper-V in Server 2016 has a Discrete Device Assignment that allows this, but couldn't find anything on Windows 10 Hyper-V.

 

Hi there

The best way would be to look through Kari's excellent tutorials on HYPER-V. Ithink he'll cover all your queries.

I don't use HYPER-V myself as I tend to run VM's on Linux Hosts but when I've tried the odd experiment using the tutorials it usually works.

Thank you. I seem to remember seeing that in my searches. I'll get a copy.

Good tutorial but did not address my issue. I cannot use any of that because when I click on the Virtual Switch it 'load fails' and it stops the virtual Machine Management Services - so I cannot add/delete/eid the switch. The Create virtual Switch goes grey. This happens each time I try to edit the virtual switch.

I can close the switch dialog and start the service, but I clicking on the virtual switch manager again kills the virtual machine management service. Dead End.

 

Please open the PowerShell and give the following command:

Code: Get-NetAdapter | clip[/quote] This will copy a list of the status of all your network adapters including Hyper-V virtual switches to Clipboard. When done, paste the content of the Clipboard to a new post in this thread, pasting it to a Code box.

Let's start from that, checking your virtual switch situation.

I can connect to the Wi-Fi (had to before the upgrade to 10130 in order to get the VM to see the Lan/Wan).

on the virtual machine I get:

OK. The external virtual switch is disconnected. Open the Network and Sharing Center and make a screenshot, then click Change adapter settings on top left and make another screenshot, post screenshots here.

 

Can't see the screenshots. See this tutorial if you need help in posting them: Screenshots and Files - Upload and Post in Ten Forums - Windows 10 Forums

I hope you see them - I just see a ghost.

 

OK, your host is not using the virtual switch, instead connecting to the network directly using the host NIC, therefore your virtual machines have no chance to connect, they simply do not find connection.

You told you have issues with the Virtual Switch Manager meaning we cannot use it to remove and recreate your switches, PowerShell has a bug in Build 10130 which makes it impossible to change the PS script execution policy so that's ruled out.

I am testing something on a test machine, I do not want to tell you a theory before I have tested it first. Might take an hour or so.

 

Wow, thanks for the extra effort. I've been hoping Microsoft would come out with a bug fix to make the Virtual Switch work again. But so far...................

Out of curiosity I thought I'd try Virtual Box. It installed but will not run. So I removed the folders (did not get to program and features).

 

It looks to me as though you have Wi-Fi bridged to Realtek RTL8188CE Wireless LAN
I don't see the other parts of the bridge. This might be why Virtual Switch is failing.

It might just be a matter of removing the bridge from Wi-Fi, but see what Kari comes back with after he tests.

 

thanks for the observation.

if that is the case, how to I remove the bridge? none of the four connections can be removed, just disabled. Have you noticed that you cannot right click on one of these items - doing so closed the dialog. I have to left click and then click on the choices that appear on a bar above the list. Strange behavior that started with 10130.
