CPU usage in games is limited to around 60% (compared to near 100% with bare-metal Windows). This strangles the GPU. I've been running Proxmox with two passed through 1070s for a while and never noticed the CPU utilization issue as 60% of a 10700k was enough to keep the 1070 fed. I upgraded to...

Was this ever resolved?

That’s so weird. Did you do it with a fresh install and make sure all your header versions etc were compatible?

I'm having the same issue. I'm sure vfio-pci has control of the iGPU (it's never bound by any of the Linux framebuffers and the screen freezes after GRUB). I must use UEFI, not SeaBios. Windows can see the GPU, but reports error 43 and gives no video output. Any help would be much appreciated.

Sorry, I have no clue. All I know is that our kernel’s last IGC change was Nov 2019 and the dev branch of that repo was up to mid 2020 (check the issues page, the guy said he was using it to fix a bug for Intel but uses the repo himself).

This fixed my VM internet problem as well. Can you post the output of ./install.sh?

Omg, I think I might have done it. Doing the following updated igc to a newer version and fixed my need to replug the cable on startup, but I haven’t verified whether it fixed the virtual machines. Here’s what I did: 1. Reinstalled Proxmox in frustration after mucking up my first install. apt...

Also, why the heck does it seem like the installer’s able to communicate just fine without unplugging the cable and plugging it back in after boot (like we have to after install?)

@oguz, is it possible to update to the latest kernel without breaking things? It seems like there’s no other option to get our NIC working,

I want to just update to the latest mainline Ubuntu/POP kernel on my Proxmox install but I don’t know enough about Linux to tell whether that will break compatibility with everything. Do you know whether this is possible? It seems nobody has bothered to backport igc and the absolute latest...

Great. I was going to try another method of installing the driver but I ran an apt full-upgrade after adding the Proxmox no-subscription repo. It updated my kernel to 5.4.65 and now the server won’t boot unless I boot with the old kernel in advanced options. However, attempting to remove the...

Why is such a popular mass-market NIC in like half of Intel’s MoBos built in the last year so horribly supported? I’ve spent the last four hours trying to figure out how to backport igc and it seems like almost nobody has bothered using this NIC with Linux. Even Intel’s official driver packs...

It looks like compiling our driver with that tool would be something like ``` make defconfig-igc make ``` Inside the backports repo.

I’m looking into driver backports. I wonder whether this package will backport the igc driver for us? https://backports.wiki.kernel.org/index.php/Main_Page

Cool! Keep me posted, I’m very inexperienced with kernel-related issues but will keep looking into it as well.

What would Intel Graphics Compiler have to do with this?

So does mine, I double checked by comparing to other PCs on the network. The VM seems to successfully acquire a new local IP and the network’s suggested DNS servers despite me not explicitly setting them (I didn’t even set those DNS servers on the host). Does this mean it was able to communicate...

I’m having the exact same issue with an identical setup. I also have an i225-v NIC (I just posted in another thread of yours as well). Any chance that could be related?

Did you ever solve this? I have the exact same issue with the same hardware. Could it be something with the I225? Even when I get it working network passthrough to my VM guests fails (Windows guest sees VirtIO Ethernet, gets an IP address that looks correct, can connect to the host, but can’t...
