EEugenMayer replied to the thread After proxmox updates: Random segmentation faults in AlmaLinux 8 VMs on Proxmox VE 9.1.@fabian we update our packages daily, within the VMs and on the proxmox server. So we updated to whatever was available to debian12 at this moment, including what is available for PVE. The reason that this is cleary proxmox and not 'vm software'...

fiona replied to the thread After proxmox updates: Random segmentation faults in AlmaLinux 8 VMs on Proxmox VE 9.1.Hi, @PVasileff are you also using the host CPU type for your VMs? @ both, could you try with a different model like x86-64-v2-AES/x86-64-v3 or a vendor-specific one close to your physical model? -

Like.
Yes, you can even confirm that yourself by rebuilding the same lxc-pve repo state twice, namely: rebuilding with Debian baseline frozen on May 1st -> binary is bit-wise identical and gets flagged. rebuilding with Debian baseline from today... -
MMrChunks reacted to BeantownEng's post in the thread Ran out of disk space getting input/output error with Like.
This one was the winner for me. The symptom that led me here on PVE 8.4.1 was the inability to login via the root account. I was able to get a shell via SSH (putty or whatever you use) and could see the /snap/certbot and /snap/core mounts were at...

TTHE_BIG_ONE replied to the thread Q35 v11.0 causes extreme corruption on many VMs Linux/BSD/Windows (STOP 0x8007025d).So, today I tested again, and now I'm not able to succeed with any fresh installations using the current build of Windows 25H2 (26200.8457). Fiona, I misspoke when I said linux VMs, as I haven't yet had a corrupted linux system, yet. The OPNSense...

BBu66as replied to the thread [SOLVED] Gegenseitige Sync Jobs - Dubletten?.Hi, ja, ist genau wie du vermutest. PBS checkt vor dem Sync, welche Snapshots bereits auf dem Ziel vorhanden sind, und überspringt sie. Der Rücklauf B→A würde daher quasi leer durchlaufen.

But RAID5/6 probably does not give good performance (in terms of IOPS, which you need for multiple VMs trying to use the drives at the same time). I though I mentioned that in my post. -
UdoB reacted to mm3923's post in the thread RAIDZ2 with 6x 480GB SSD only 1.35TB usable total with Like.
Hello Udo, Thank you very much for the explanation. I use the datastore for VMs only; static data is stored on a NAS with HDDs. From this, I conclude that I should probably use RAID10 (i.e. 6x mirror vdevs) for performance reasons as well... -
news reacted to UdoB's post in the thread Significant IOPS Drop in Proxmox 9.1.9 VMs Compared to Other Hypervisors with Like.
You did not say anything of the underlying filesystems...? For ZFS it may be expected as ZFS does a lot more work than classic filesystems under the hood, resulting in multiple IO-operations used for metadata etc...

fiona replied to the thread Q35 v11.0 causes extreme corruption on many VMs Linux/BSD/Windows (STOP 0x8007025d).What you could also test, does the issue happen when you switch to a different Async IO setting for the virtual disk (in the Advanced settings when editing the disk in the UI)?

The deprecation itself was not strongly influenced by that, but the decision to communicate it more actively was in fact primarily driven by it. Normally, we only mentioned it on the side once a new kernel became the default. In the past, we...

Vvmwombat replied to the thread nicht vergessen: UEFI-Zertifikate Eurer EFI-Disk Instanzen 06.2026!.Erstmal vielen Dank für diese tolle Zusammenfassung! Das Ablaufdatum am 15.05.2026 sehe ich auch bei meiner Kontrolle in einer VM. Warum ist denn nun dieses 2023 UEFI Zertifikat auch schon wieder abgelaufen? Das versteht doch keiner mehr.

LLe_Coyote replied to the thread LXC: cannot mount /run inside guest after PVE 8 to 9 upgrade (was: loopback interface not coming up).Hello I have confirmed that this problem emerges after upgrading a node from PVE 8 to 9. In other words, the guest was working very well in PVE8, but in 9, network breaks down. It does not happen for all the guests, but I have not been able to...

fiona replied to the thread Q35 v11.0 causes extreme corruption on many VMs Linux/BSD/Windows (STOP 0x8007025d).Hi @THE_BIG_ONE, please share your /etc/pve/storage.cfg and the configuration of an affected VM qm config ID with the numerical ID of the VM. What storage type and format is used for your virtual disks, qcow2/raw/...? What was the exact error for...

UdoB replied to the thread RAIDZ2 with 6x 480GB SSD only 1.35TB usable total.Well..., it is "50%" versus "66%". For this 16% more space you lose two third of available IOPS. Six mirrors have three times the IOPS as two RaidZ2 offer, every single vdev counts. If you are storing VMs on the resulting pool then this is...

Zu dieser Thematik habe ich auch noch etwas Senf. Dieses Thema ist wirklich verwirrend und ich trage hier mal meine Erkenntnis vor. Was hat es mit den RegistryKeys auf sich: Windows selbst kennt für sich nur 2 ligitime Wege, wie sich die...
