NNachdem Kernelcare den Support für Proxmox eingestellt hat ist die Frage, welcher Dienstleister bietet noch Kernel Live Patching für Proxmox 9 Umgebung an? Oder hat Proxmox selbst dies vielleicht direkt auf der Roadmap. Gerade in Umgebungen bei...

Ggarysday replied to the thread 8021q not working.OMG, you won't believe this .. For some reason, I installed the new version on to an m.2 drive in my chassis, but the boot sequence was coming from an old attached disk from somewhere - that old disk has an old (broken) proxmox install on it, so...

Beside all the noice i created, i can fairly confident say, downgrading qemu to 10.1.2-7does fix the actual issue. I no longer have any segfaults on any of my proxmox servers, with qcow2 still in use. -

@EugenMayer - I'm breaking your point of view :) I apologize if I sounded offensive or insulting. I'll describe my thoughts out loud, I don't oblige anyone with them and they are NOT specifically directed at @EugenMayer. I'm just sharing. If I...

IInterneIT replied to the thread [SOLVED] Boot issue after upgrading proxmox 8 to 9.This is issue is solved. I managed to install the md raid tools in the rescue environment, chrooted in the pve install and reinstalled grub. Was a nice learning :)

Ffever_wits replied to the thread After proxmox updates: Random segmentation faults in AlmaLinux 8 VMs on Proxmox VE 9.1.@fiona, can I or @PVasileff help with something to diagnose the problem faster? If you consider it, later today I can provide direct access to minihv for the proxmox team to diagnose the problem. This is just an idea/suggestion. Just because I...

Ggarysday replied to the thread 8021q not working.I still get the same problem, its like deb / proxmox can't create VLAN on this node for some reason.. FYI IT works just fine , I used to have 4 of these in a VSAN cluster with VCF running, so I know the H/W supports VLANS, it looks like 802.1q...

fiona replied to the thread After proxmox updates: Random segmentation faults in AlmaLinux 8 VMs on Proxmox VE 9.1.There was no change. We always picked up QEMU releases as they came in, moving them along to pve-test and pve-no-subscription before a Proxmox VE point release made them available in the enterprise repository as well. Also, QEMU does not have a...

fiona replied to the thread After proxmox updates: Random segmentation faults in AlmaLinux 8 VMs on Proxmox VE 9.1.Note that this would be a segfault in QEMU itself so the whole VM process would crash, so it's unlikely to be the same issue. And it would be specific to aio=native which is not the default and doesn't seem to be set in the configurations shared...

Hi @fever_wits, on the third server, could you first test the older kernel builds with ZFS support: proxmox-kernel-7.0.0-3-pve proxmox-kernel-7.0.2-1-pve proxmox-kernel-7.0.2-2-pve proxmox-kernel-7.0.2-3-pve For each kernel, you can run...

Hello, I spoke to @PVasileff , he tested older kernel versions. That doesn't help. As far as I can tell it's related to disk creation and management. On minihv (Qoton Q20332G9 S20) today we created 2 VMs: - Alma 9.7, then updated - after the...

Thanks for all the informations and work already done above! I'am currently on the way to test the downgrade of pve-qemu-kvm to 10.1.2 to see if that helps. In my book, the kernel of the host is less likely the cause here (this is only a bet). I...

Here are the relevant `/var/log/apt/history.log` entries from the AMD Proxmox host `amdhv`. This is the host where the same restored AlmaLinux 8 VM did not show the issue before the update, but started showing segmentation faults immediately...

Thanks for the replies. I want to add another datapoint. I gave a backup of one of my affected AlmaLinux 8 VMs to a colleague, and he restored/tested it on two of his own Proxmox hosts. Also, on the problematic AlmaLinux 8 servers, fsck has...

When host is used, there can be quirks that are not present with virtual models. I'm not betting on it resolving the issue, since multiple physical models are affected, but there is a chance and it is a valuable data point for the investigation.

Are you expected that 'non-host' / x86-64-v2-AES/x86-64-v3 should be less error prone than host? I would have suggested, that this is unexpected, but i follow your advice, if that is the case

The v3 model does include flags for avx, use v4 if you need the avx512 flags too, and a vendor-specific one close to your physical model will support those flags too.
