Realtek and Hyper-V weirdness

Earlier this morning I finally bothered to install OpenBSD VM in my main desktop to be used as main dev system. With NFS from main server as its main storage. Except it was kind of slow so that project is scrapped and now being replaced with Debian. Or maybe I’ll try FreeBSD later.

That’s not the point of this post though. The problem is soon after I boot the new VMs, my network started acting up. It randomly disconnects every once in a while. It disconnects so often it’s not even funny.

Here’s the error message in Windows Event Log:

ネットワーク インターフェイス "Realtek PCIe GbE Family Controller" はリセットを開始しました。ハードウェア リセットの間にネットワーク接続が一時的に中断します。理由: The network driver detected that its hardware has stopped responding to commands。このネットワーク インターフェイスは、最後に初期化されてから 57 回リセットされました。

I tried various drivers and none of them seem to help. It’s mostly fine if I’m only running single Windows VM.

The only other ethernet card I have is yet another Realtek but I figured might as well try it and see how it goes.

And pretty well so far it goes. No disconnect so far. Hopefully this will continue to work until my 10GbE cards arrive. Which then it’ll be FUN TIME 🌈

I’m getting it from a US seller through ebay though so it’ll take a while until it arrives.
