Hello,

I did make this script to passthrough my Geforce FX1600 with proxmox 7.4
I did a fresh installation launched the script, restored my VM Windows 10, but the VM starts but no display.

Do you know why with the latest version of Proxmox the config doesn't work, what did change ? Many Thanks

Code: 
#!/bin/bash

# Vérifier si l'utilisateur est root
if [[ $EUID -ne 0 ]]; then
   echo "Ce script doit être exécuté en tant que root."
   exit 1
fi

# Modifier /etc/default/grub

Hallo Community,

für dieses oder spätestens nächstes Jahr sind bei uns neue Hosts geplant.
Kurze Konfig-Info : Cluster mit 3 Hosts, Insgesamt ca. 50-60VMs, alles Windows, davon 10 Server und davon 4 mit SQL-Datenbanken.
Die Storage Anbindung soll zum einen lokal mittels CEPH (Verbindung mit 100GBit/s direktverbindung ohne Switch), zum anderen auch ein vorhandenes iSCSI-Cluster (Multipath 2x 25GBit/s - ggf auch 4x) erfolgen.
Je Host kommen NVMes zu Einsatz sowohl für OS als auch CEPH, 4...

Backup error - job failed with err -5 - Input/output error

Hello everyone.

We seem to be having storage issues with our Production servers. ZFS is telling us a disk has failed (the server RAID card says the disk is OK!), and it insists that we need to create the ZFS storage again.

We are trying to backup all data, but it is impossible, it gives an error "job failed with err -5 - Input/output error"

So basically, we cannot backup any info because it refuses to do so, and its just telling us to start over which is impossible

Proxmox says we...

Recently, I've noticed that reboots and shutdowns of the host are not gracefully shutting down VMs. They are stopped almost immediately.

There are several errors in the logs, but I do not know how to interpret them. I'd appreciate any help in debugging this issue!

With the recent shitcom dumpster fire, I wanted to test and see how Proxmox would look in my personal homelab, and then give my findings to my team at work. I have 2 identical hosts with a TrueNAS Core install running iSCSI storage Datastores over 10G DAC cables to the hosts on another host.

I set up one of the hosts to run Proxmox and start the migration, which I will say, was awesome during this process. I had some issues getting the initial network set up and running, but after I got the...

Hello,

I have a setup with a standalone node without a cluster configured. I want to add a LXC container to the node but this isn't possible because of the error message "Node seems to be offline" in the GUI when I try to create the new container.

I read the documentation and if I'm not mistaken these are the steps to create a new cluster and and configure nodes (https://pve.proxmox.com/wiki/Cluster_Manager#_preparing_nodes). But it also writes that it isn't possible adding a...

We recently uploaded a 6.14 kernel into our repositories. The current 6.8 kernel will stay the default on the Proxmox VE 8 series, the newly introduced 6.14 kernel is an option.
The 6.14 based kernel may be useful for some (especially newer) setups, for example if there is improved hardware support that has not yet been backported to 6.8.
This follows our tradition of upgrading the Proxmox VE kernel to match the current Ubuntu version until we reach an (Ubuntu) LTS release, like the 6.8...

Hello, everyone,

I'm integrating the PVE with one application using the API, however, when I try to define an affinity on the VM, the API returns error 500 with the message "only root can set 'affinity' config".

Is there anything I can do to solve this issue?

API Endpoint used:

Bei der Konfiguration eines Filters (extener Dovecot/Sieve) ist mir aufgefallen, dass PMG Status E-Mails nicht erfasst werden. Der Filter sucht im Header nach dem Vorhandensein eines "To:" Eintrages, der bei PMG-eigenen E-Mails aber offenbar nicht vorhanden ist (also als Sender und nicht als Gateway arbeitet).

Die Zieladresse "reporting@ domain.tld" taucht zwar als Zitat im Header auf:

Hallo.
Hier ließt man viel über das Thema Backup des PVE. Scheinbar ist das offiziell auch 2025 noch nicht möglich.
Wie sichert ihr euren PVE ?
In manchen posts ist die Rede davon das so ein Host ja schnell aufgesetzt ist. Dem stimme ich nicht zu. Und ich bin sicher nicht der Einzige welcher USB Platten eingerichtet hat, Eine usb Antenne an LXC für eine Heimautomation weiterleitet, und eine PCI Weiterleitung einer Grafikkarte zur Encodierung mittels Plex am laufen hat. usw.

Liebe Community,

Was ich bisher gemacht habe
- Backup vom /etc und dem var/lib/.../dump Ordner
- das zurück kopieren auf den frischen Proxmox Setup der neuen NVMe führte nicht zum Erfolg, da die Partitionen nicht angelegt sind. (?)

I used a 3-node group to form a PVE cluster, and when the management gateway address was unreachable (core switch reboot), the three PVE nodes almost automatically restarted at the same time.
By using the 'Journalctl - b -0 | grep reboot' command to query logs on each node: “kernel: softdog: soft_reboot_cmd=<not set> soft_active_on_boot=0”“cron[3572]: (CRON) INFO (Running @reboot jobs)”。 By analyzing the logs, it is possible that the kernel module softdog initiated a restart...
