pbear Posted December 19, 2020 Share Posted December 19, 2020 (edited) Hello, I've been running Unraid since some weeks, first on a QNAP, then with a Ryzen 2600x without any problems. But because it was a mini-itx and I wanted to upgrade the box, the drives, to add a quad nic card etc.. I just mounted a new computer with a Core i5. I've used the same disks for now, and the same USB key. It boots correctly, I've got back my array and everything, but I don't see any graphic card when I create a VM. In the info I see: CPU: Intel® Core™ i5-10400 CPU @ 2.90GHz HVM: Enabled IOMMU: Disabled Cache: 384 KiB, 1536 KiB, 12 MB I've checked again in the bios and the virtualisation capabilities of the cpu is enabled (actually I can't even change that) I see my two graphics cards but in a "no IOMMU group" (I don't know what it means): So what I do wrong ? 😟 Edited December 19, 2020 by pee_bear Quote Link to comment
Squid Posted December 19, 2020 Share Posted December 19, 2020 Virtualization in the BIOS only enables VT-x. You need to also enable IOMMU / VT-d in the BIOS for passthrough to work. Usually its buried in a separate submenu. 1 Quote Link to comment
pbear Posted December 19, 2020 Author Share Posted December 19, 2020 It is strange: root@Home-Server:~# dmesg | grep IOMMU [ 13.396325] AMD-Vi: AMD IOMMUv2 driver by Joerg Roedel <[email protected]> [ 13.396327] AMD-Vi: AMD IOMMUv2 functionality not available on this system It looks like the USB flashdrive is still remembering my precedent CPU and did not refresh with the current intel cpu 🤔 @Squid I'm almost sure I've checked every menus and submenus of the Bios. I will check again ! Quote Link to comment

Then I came across this video https://youtu.be/OtTkbfscU3g?t=90 The guy also has a MSI motherboard. We have to go to OC (overclocking) menu. And then scroll down to the bottom. I would never have thought to go there AND scroll down. (because actually I opened it once, quickly, but I didnt see anything related to virtualisation). Thank you for your help Squid.
