VM Windows Server on "metered connection"

[150d]

Hi,

I'm running a number of VMs with Windows Server (2022 and 2025) on Proxmox v8.2.7 using VirtIO drivers v0.1.262 (also tried an earlier version.)

On all of those VMs Windows reports network on a "metered connection", even though this is disabled in the UI and in the Registry ("NetworkList/DefaultMediaCost"). Interestingly, it does not happen on a Windows 10 machine, only on Windows Server VMs. It doesn't seem to matter whether the VM is configured for VirtIO NIC or E1000.

Has anyone ever encountered this and managed to solve it? There are a few mentions of this problem over the internet, but no solution that I could find. Many of them are in a virtual environment, not only Proxmox/QEMU, but also HyperV. It's completly unclear whether this is an issue with the drivers, a bug in Windows Server or a settings problem.

Regards

There are some known bugs in VirtIO version 0.1.262. Please create a snapshot of your VM and install a slightly older version of the network driver for VirtIO, this may already solve your problem.

Afraid not, no change with VirtIO v0.1.248 from your link. I had already tried v0.1.240, also nothing.

Additionally I just tried the Realtek NIC emulation - still "metered connection".
