[BUG] - VLANS are broken in Atlas

[agowa]

Description

VLANs don't work. Neither ones created nor after installing Atlas work once the Atlas setup is complete.

Steps to reproduce

1. Install Atlas
2. Install Hyper-V Services
3. Create a virtual switch with a VLAN for the host (or try to create additional vlan ports manually using powershell)

Expected behavior

vlans working or a ticket about them and notes about how to enable them (or a post install customization script to re-enable them).

Actual behavior

Vlan appearing to be configured but not working. Traffic is leaving untagged.

Hello,

I think the issue comes from the "Executable/Finalize.cmd" because it dumps a lot of network adapter options in the registry. Check the block between line 57 and 131.

Maybe using the "Executables\AtlasDesktop\8. Troubleshooting\Network\Reset Network to Atlas Default.cmd" should fix your issue?

Network settings are being refactored for next release, and I presume that's the issue. For now, try the script mentioned above

I now got it working by running the reset network to windows script, removing the virtual switch, recreating the virtual switch, recreating the virtual adapter, re-adding the vlan setting to the adapter.

Maybe it helps. Before deleting the adapter using the command to set a vlan didn't find the network adapter. Could it be that it is somehow partially deleted?

PS C:\> Set-VMNetworkAdapterVlan -ManagementOS -VMNetworkAdapterName VLAN20 -VlanId 20 -Access
Set-VMNetworkAdapterVlan: No network adapter was found with the given criteria.

PS C:\> Remove-VMNetworkAdapter -ManagementOS -Name vlan20
Remove-VMNetworkAdapter: Failed while removing virtual Ethernet switch connections.

Closing as this will be fixed next release.
