We're using Windows Server 2019 to run Hyper-V that runs a virtual machine. When we initially created this virtual machine, we also created a virtual switch and assigned it to the VM, so that it would be able to connect to the network.
When creating this new virtual switch in Virtual Switch Manager we selected 'External Network' for the Connection Type.
When doing this it transfers the ip address configuration of the physical network adapter to the new virtual network switch.
All this works perfectly and the VM can reach the network when this setup is completed.
However for some time we have seen that on some of our Windows Servers the ip address was moved back from the virtual network adapter to the physical network adapter. Obviously at this point the virtual machine looses the connection to the network.
Since none of my colleagues confirmed that they have done this manual move, could it be that this can happen automatically ?
I've googled around but couldn't find a clue on this.
Do you know of any circumstances where this 'rollback' can happen automatically ?
Thanks for your ideas.
