Without fail every time you try to create a VM the interface will crash the tab completely (to the point you cannot use it, you have to close it an open a new one). The tab starts to use 100% of the CPU. There's some serious issue there as the inspector doesn't respond when this happens - if you...

Yes, I actually use passed to a DSM install. This sounds familiar to me in one scenario: USB reconfiguration due to speed. Make sure your physical controller you connect the device to is the same in generation (1.1 vs 2.0 vs 3.0) as the virtual one. Many devices are fine with being re-connected...

I was testing it before releasing new packages to the public ;) With any new release you can keep the kernel (especially with such small updates like here, we're still on 5.4). New packages are released on my GH (https://github.com/kiler129/relax-intel-rmrr/releases) and indeed it runs...

No, it closes sungly. You cannot really keep it open as this screws up the airflow. With the case open and 100% load on all cores I hit ~97°C while with case closed the max I saw was 80 (running stock "35W" cooler + 40mm Noctua). Two-and-a-half reasons: 1240v2 is substantially faster than...

Haha thanks ;) Gen8 is an amazing piece of hardware for a homelab, especially since you can plop Xeon E3-1240v2 & 16GB ram there. Mine is actually running with 9 hard drives in it. The easiest way is just plugging something into the port you want to forward and assigning using "Use USB Port"...

Yes, at least the front USB ports are working flawlessly. While I don't use it myself I checked it quickly and it works as expected with a single port and hotplug: You just need to assign it in the Hardware tab:

Oh, I see what you mean. I was thinking about it but decided to not include an additional guide for creating a patch yourself. I did this because I believe there are mutually exclusive groups of users: Most users will simply install the debs and forget (I actually have three friends also...

Of course, downloading packages is just really a shortcut for people who don't want to go through the process of building the kernel. The repo contains two install instructions for Proxmox: Building from sources Premade packages Is there anything you're missing here you think can be added...

Yes, it is running Proxmox 6.2-4 with Linux v5.4.65-1. For the ultimate test I was actually stress-testing the solution with the worst case scenario: passthrough of a RAID/HBA soldered in the motherboard of my HPE Microserver Gen8 which is also tied in one IOMMU group with some LPC controller...

I tested the packages throughly and prepared a complete rundown of the issue with all the possible fixes & technical reasons. https://github.com/kiler129/relax-intel-rmrr Anyone interested can either download precompiled debs or build them from sources. After installation flipping a kernel...

The thing is it was always this way. I looked around the changes in 5.4 and they essentially just added checks to more places than just IOMMU API. After reading about IOMMU and RMRR in general I realized how dangerous of a game we're playing here. Each x86 system has some untouchable memory...

It's actually a terrible solution as described in the QEmu bug report you linked (https://bugs.launchpad.net/qemu/+bug/1869006/comments/18). We can only hope that iLO doesn't tinker with these regions and just reads them.... but if it writes them... well, that may lead to a catastrophe if the...
