Hi,
thank you for the report!

Yes, we can confirm it's broken again in
pve-qemu-kvm >= 8.1.2-1.This is indeed the culprit. Since that commit was only fixing a cosmetic issue,
pve-qemu-kvm >= 8.1.2-2 will include a revert to avoid the breakage until there is a proper fix.
Great! Happy to help. We're all in same boat here, so we're happy to collaborate on making sure this is smooth for all QEMU based folks. Oddball bugs like this are never fun.
Good thing is that I think we've at least got this bug cornered, so now its just a matter of "who dun it?" in between what QEMU fixups can be made vs what Microsoft might need to engage on to fixup their side.

Hello,
after diging around with the same issue and testing many ideas from the forum and the www, here is what worked for me.
after diging around with the same issue and testing many ideas from the forum and the www, here is what worked for me.
- Install Windows and start it up as usual
- Mount the VirtIO Drivers Disc
- Install Virtio-Win-Gt
- Install Virtio-Win-Guest Tools
- Open the Device-Manager and Deinstall the ReHat Virtio Ethernet Adapter (Select Delete Driver Files)
- Seach for changed hardware
- Ethernet-Controller will appear
- Right click, install drivers and select the mounted disc as source for drivers (Make sure to include subfolders)
- Windows will install the drivers from the disc and the eth-adpater should be usable
So I tried to test this. First, I stopped the machine > changed the machine type (OS Type in the hardware settings) from q35 to the default i440fix. That didn't seem to help. I also tried creating a new machine with the correct settings, and that fixed it!!!
Thanks!
Hi,
did you install the latest version of the virtio-win guest drivers https://pve.proxmox.com/wiki/Windows_VirtIO_Drivers ? Those are required for VirtIO devices.
why would you recommend that when the issue persists since multiple years?
There's some hope that applying KB5046615 could work, see the end of the upstream thread on the issue and, optionally, follow the link from there.

Hi,
I just stated that installing VirtIO drivers is required to use a VirtIO network device with Windows. The issue does not persist, see below. If you do still have an issue with VirtIO drivers installed and using current versions, it most likely is not the same issue. Please open a separate thread and provide all the necessary details.
As already mentioned earlier in the thread,
pve-qemu-kvm >= 8.1.2-2 included a revert to fix that issue, so it hasn't affected Proxmox VE since 1.5 years ago. And the proper fix mentioned there is included since pve-qemu-kvm >= 9.2.0-1 (and there, the revert could be dropped).
