That's from my Fedora 43 vm with passthrough enabled.

@thomasp I'm struggling so much to find the time to do it, and my colleagues are equally busy, but I'll try to make it happen this week!

No pun, just wait for everyone to get back from our yearly Vates internal event

@hoehnp we're aiming at sharing a very first public version before end of year, but don't hope for it to be anything complete or stable

@Joe_dev I have a MF unit with similar igpu. I was not able to get it working under any virtualization platform. There is something about amd igpu that makes passing it hard. I believe some have had it working under proxmox with custom kernel and video bios. I never bothered trying all that out so i just gave up on the unit.

Maybe that's my issue ? Investing this part # journalctl -k | grep -i nvidia [image: 1763219509282-aaed86b6-1384-434e-ac5d-bca510405f33-image.png]

Adding this to our topics to discuss

Since GPU passthrough is involved I'd ping @Team-Hypervisor-Kernel

@ph7 huh, that is weird. I'll try to troubleshoot more over the weekend. Thanks for pointing it out. @olivierlambert said in Upgraded RAM, It get's detected but not used. Any ideas?: I would first upgrade the BIOS of the motherboard. Consumer grade hardware is pretty buggy in general when you are using "advanced" features, sadly. That's the first thing i tried, no luck unfortunately

Hi, Are you sure your GPU is correctly fed via the power connector?

What GPU do you have? I thought I read something about NVidia's newer stuff having vGPU without the expensive licensing and hardware. But it's possible I'm just conflating that with the increase in concurrent NVENC encodes. On the bright side, you can always get a cheap GPU and just do passthrough with it. I do that for my Jellyfin server with a 2060, it's very easy to do in XCP-ng now and works super reliably.

@andSmv Thanks for taking a look at it. It's not really needed for a modern platform.

Reboot seems to have fixed it and made it visible. Leaving this post up so others have all the commands in one place. [14:15 cloud ~]# ethtool -i eth5 driver: i40e version: 2.26.8 firmware-version: 9.50 0x8000f255 23.0.8 expansion-rom-version: bus-info: 0000:5e:00.1 supports-statistics: yes supports-test: yes supports-eeprom-access: yes supports-register-dump: yes supports-priv-flags: yes

@olivierlambert thank you very much, you are helpful

Host shutdown with force flag should shutdown the VM, IIRC.

@gduperrey The thing is, the i40e driver works fine for me with the regular kernel. I was hoping to try kernel-alt to see whether it would resolve my erroneous CPU thermal shutdown issues (to narrow down whether it's a kernel issue or not), but then I ran into the driver issue. I can try that alt driver, though, and see if it works with kernel-alt for me.

Hi, @samuelolavo can you run the following command on the dom0 and paste its output please: grep -A5 "'XCP-ng'" /etc/grub.cfg Then also run lspci -vvv xe pci-list xl pci-assignable-list

@chicagomed there's no need to be editing grub for pass thru, I would use the standard commands and avoid corrupting grub in the process.

@olivierlambert said in HCP-NG 8.3 freezes and / or reboot on HGR-SAP3 by Ovh: You can edit your first post, which contains the title thanks a lot I'll wait until next week to disable deduplication (never on Friday )
