Foro Proxmox Support Forum

hello all! i've been working here and there on tailmox , a means of clustering together proxmox servers via tailscale to allow for features such as staged zfs replications/migrations across geographically distant nodes. i've been running the dev version for a while now on my own cluster, and i have recently wanted to surface data in regards to cluster performance, link latency, corosync statistics, etc. while i'm not quite ready to ship a numbered version just yet, you can view stats...

Hi, I have two PVE clusters (PVE-A & PVE-B) running on 8.4.14 & 8.2.4 for more than 2 years (same configuration), a newly deployed PVE with PVE 9.0.3 reused the configuration of PVE-A & PVE-B. BUT the firewall does not work... Config summary: 1. Enable FW on DC level with security-group; 2. Enable FW on physical host level with same security-group in step_1; 3. Enable FW (in "Option" menu) on VM&LXC level with white-list (ipset & fw entries) trouble shooting summary (Per gemini... Read more

I have a cluster connected to storage via Fibre Channel, with a LUN presented to the cluster and multipathing configured. I want to use it as a backup directory; what steps must I follow to make this LUN available as a directory for all servers in the cluster?

Hello, I'd like to experiment with the new OCI container-in-LXC support in PVE 9. I've got a relatively simple container picked out to try (basically, an internet uptime monitor to detect WAN disconnects), but it's going to need a bit of external storage. I know I can do this with bind-mounts, but I'm not sure how to configure everything. Usually, I'd set up a container's bind mount in Docker compose if I'm using a Docker image. I know I can add a bind mount to an NFS or SMB share on... Read more

Hi everyone, I’d like to share an issue we’re experiencing and see if anyone has encountered something similar or can provide some insight. We have been testing Windows Server 2025 on Proxmox VE 8.4 (QEMU 9) as well as Proxmox VE 9.1 (QEMU 10) . We tried different CPU configurations and resource allocations, but in all cases the user experience is noticeably worse compared to Windows Server 2022 and earlier versions. Observed issue​ The main problem appears... Read more

Hiho, wir wollen in Zukunft von Mircrosoft HyperV weg und hin zu Proxmox wechseln. Nach möglichkeit sollten die "Funktionalitäten" so ähnlich wie möglich sein. Aktuell: - viele Kunden mit Einzelserver(Hardware) + 2-5 Virtuellen Maschienen mit Microsoft HyperV - Atera wird als Monitoring Software ingesetzt ( CPU-, RAMauslastung, Festplatten SMART, Kapazität,... ) - Hornetsecurity wird als Backup verwendet ( NAS und Onlinespeicher. ) Fullsicheurng + Inkrementell Die ersten...

Hallo zusammen, ich stoße bei einem 4-Bay NVMe Gehäuse (ASMedia ASM2464PDX Bridge Chip) auf ein reproduzierbares Stabilitätsproblem beim PCIe-Tunneling unter Proxmox VE. Auf demselben Host läuft die Hardware unter einem normalen Debian Trixie (Kernel 7.0) absolut stabil im echten PCIe-Tunneling. Unter Proxmox VE (Kernel 7.0.14-pve) bricht der Retimer-Link jedoch exakt alle 10 Sekunden ab. Hier ist eine Zusammenfassung des Problems, der bisherigen Diagnose und der Testergebnisse... Read more

Question folks- I am building a simple PVE cluster with 2 UCSC-C220-M8S machines and dedicated Qdevice. This is to host a handful of backend VM's including one primary and backup ISE boxes on a 2 Nexus access switches attached to a vpc L3 core. ISE aside, no production apps so to speak... It's a very basic simple network. Does UCS c220 out of the box have enough hardware? The vics would be dedicated to a active passive linux bond and a couple HA sync segments. The handful of vm's would... Read more

Hi, We have a PBS backup a couple of Proxmox servers in a datacenter. We have another PBS setup at our main office and I configured a sync job on it to sync all the backups off-site. It's configured to sync everything (root namespace). Now I want to move more of our home-grown backup solution into PBS. In particular, there's a file-server at the office that needs to be backed up, and then synced off-site. My idea is to backup the office file server to PBS, and then sync that back to the...

When the first crash occoured I had this Problem: Code: [ 5880.143371] igb 0000:05:00.0 nic1: NETDEV WATCHDOG: CPU: 6: transmit queue 1 timed out 5021 ms I switched to proxmox two weeks ago. Before proxmox i had OMV (Debian) with 6.1.0 on the system and no poblems.

Hallo allerseits, entsprechend der Empfehlung , SPICE als Console für Desktop VMs zu nutzen, habe ich auf meinem Windows Notebook spice-viewer installiert. Die Tastenkombination SHIFT+F11 für Toggle Fullscreen funktioniert, die Tasten SHIFT+F12 für Release Cursor hingegen nicht. Ich kann auch keine andere Taste konfigurieren, weil der Dialog "Keyboard shortcuts" gar keine Änderungen zulässt. Alle Felder sind read-only. Eine Recherche im Netz ergab nur einen einzigen Thread , der... Read more

First, I want to just hands up state that my setup is very much unsupported, I know that. But I have been playing with getting proxmox running on the Oracle Free tier ampere server and that works just swell. I want to play with it to see if I can get it running reliably on OCI, with a IPsec tunnel to my in-prem cluster. Now the problem comes with adding containers. The setup does not support running VMs (as it is running on cloud vps) but running LXC containers works just fine. Networking... Read more
