I'm afraid there aren't any bios updates...the device is a chinese mini pc from aliexpress. I've spoken with the seller and he told there aren't any, at least not official ones. I don't think it's a bios issue, but something regarding the passthrough on the newer devices . maybe the kernel from xcp is too old, although it's heavily patched.

@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

Thank you very much for sharing your findings Adding @Team-Documentation-Knowledge-Management and @Team-OS-Platform-Release to check what's next on our side

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

@rhkean note we did not publish any build yet (there is code available, but I wouldn't advise anyone to jump on it yet )

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

I'm going to build an updated installer with an updated bnxt_en driver, as more and more servers require it.

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 )

Ah great Maybe something to update on the doc. Pinging both @Team-Hypervisor-Kernel and @thomas-dkmt

I've seen cases where the a hard reset is forced in case some devices can't DMA. Maybe it's related. If that's the case, something should show up in the IPMI, and the crash is usually instantaneous; otherwise, there is some delay (~5 seconds) between Xen/Dom0 crash and actual reboot.

@mohammadm Could you share information about your configuration. What system do you use on guest VM? What drivers you are using on guest VM? On VM you are using bios or uefi? I am trying to get to the point where VM can detect GPU but I have some problems. Recreating your guest configuration can simplify things.

Understood, thank you.

@DustinB Hmm - just got done running mem86+ - 4 passes -- all 14 tests. No RAM errors. I wonder the what would cause this error? I'll probably just save config and reinstall. So strange.
