migration

Hello, I get often asked by customers how to install the virto drivers before the migration in a way that they can be immediatly be used with virtio scsi single devices without an intermediary boot using an ide drive and an empy virtio scsi single device. And today we solved the issue in a...

Hallo zusammen, ich stehe vor der Aufgabe, eine größere Anzahl an VMs von einem VMware vSAN Cluster auf neue, eigenständige Proxmox-Nodes mit lokalem Storage zu migrieren. Mein Ziel ist es, den neuen ESXi Import Wizard von Proxmox zu nutzen, um die VMs direkt über die API zu streamen. Dazu...

Hola comunidad, les comparto una solución que he implementado para mantener sincronizados dos servidores Proxmox (o más) con control dinámico de dirección, ancho de banda y parada/arranque sin detener el proceso principal. Está pensada para entornos donde se necesita un servidor en espejo...

Hello, can anyone please shed some light on these messages that seems to occur during every migration between say `hv02` and `hv05`: 2026-04-04 15:13:23 [hv05] kvm: warning: global PIIX4_PM.disable_s3=1 not used 2026-04-04 15:13:23 [hv05] kvm: warning: global PIIX4_PM.disable_s4=1 not used

Hi All, I have been using Proxmox for a couple of years since B-Day, and I'm working through a POC right now internally and have everything setup with the available hardware to me, but I've found a potential limitation and cannot find anyone else talking about this, either I can't get the...

After presenting my modified ISO in the German forum section some time ago, the optimized version is now available in English. Since I came up with the method for migration with minimal downtime, I have more good news today. It is possible to install the Virtio drivers in advance so that...

Hi all, I have a container on a thinly provisioned LVM volume. I want to extract the disk that backs the thin volume out of the system running Proxmox, but run into the issue that thin volumes don't support shrinking. After moving stuff out of the way, there is a lot of air in the container...

Hello everyone! I was wondering if someone could give me a couple tips on the configuration for the network used by Migration Settings, to migrate VMs from one node to the other. We have a cluster with 15 nodes which are configured with 2 networks: Ceph is configured to use a Bond made of 2...

Not sure if it should be posted here or in PVE, but I do it here since the migration will be startet using the PDM GUI. Simplified setup: Datacenter "Site A" node1.sitea.company.com node2.sitea.company.com node3.sitea.company.com Datacenter "Site B" node4.siteb.company.com...

Greetings, Since moving to PVE 9.x (now using 9.1.1) from 8.x, live migrations would sometimes stall. The logs show: 2026-01-06 10:19:29 conntrack state migration not supported or disabled, active connections might get dropped 2026-01-06 10:19:30 use dedicated network address for sending...

Over the holidays, I upgraded two Proxmox servers to 9.1.2. Unfortunately, the network connection died during one of the upgrades. I then repeated the update manually. Unfortunately, an error occurred and the first network is no longer working properly. I can log in via the second network and...

Tried the live VM migration between clusters, but got the error: api error (status = 400: api error (status = 596: )) What is required to be configured in each cluster to perform these type of migrations? Root ssh keys authorized? Firewall issues? Each server in a cluster uses a Let's Encrypt...

I migrated a Windows VM from VMware to Proxmox. RAM hot plug works fine, but CPU hot plug does not. Virtio drivers are already installed inside the VM. CPU is added from Proxmox UI, but Windows does not detect it. Any idea what I am missing or what to check next?

Hi everyone! :) I'm super happy with tagging my machines in one PVE setup i've made. I'd now love to re-use /just the same/ config on a new PVE install. Where does Proxmox store the tag config, and can I just rsync-over-ssh copy that onto the new machine? Grateful for any insights! :)

Testing out the new (and awesome) PDM. I was able to add two clusters, one which has PVE 7 servers, and one that has PVE 8 servers. Is it possible to live migrate VMs from the PVE 7 cluster to the PVE 8 cluster? Would help us perform upgrades and migrations more smoothly.

Hallo zusammen! Ich habe einen alten Fujitsu Primergy RX300 S8 laufen und an einem in den IT-Mode geflashten HBA sämtliche Platten angeschlossen (siehe Bild). Zur Zeit habe ich mein Proxmox-Installation gemirrored auf den beiden rechten Platten (welche momentan noch drehende "Scheiben" sind)...

Zwei Hosts, SAN mit LVM THICK und Snapshot Funktionalität angebunden. Bei der Mirgation bekomme ich folgenden Fehler. 2025-11-17 08:30:56 starting migration of VM 100 to node 'pve3' (141.20.156.143) 2025-11-17 08:30:56 starting VM 100 on remote node 'pve3' 2025-11-17 08:30:57 [pve3] can't...

Hallo in die Runde, leider gibt es das Problem, dass Windows Systeme bei der Migration zu Proxmox Ihre Netzwerksettings verlieren. Proxmox kann hier nichts für, da es sich um eine Eigenart von Windows handelt. Wer den Gamechanger von Falk kennt, kann Windows VM's bereits sehr schnell und ohne...

Backgroud: I migrated a VM from one PVE node (pve1) to another node (pve2). After migrated sucess, the original VM (VM on pve1) show "locked" status [Config locked(migrate)]. Question: What's the reason it is locked? Cloud I use qm VMID unlock to unlock the VM? Any potential issue? (So that I...

Hi all, is it correct that by default Proxmox 9 in a 3 node cluster configuration with CEPH for VM migration use VMBR0 network? Current node network config does use a separate network for CEPH Cluster (10.10.10.x/24), CEPH Public (10.10.20.x/24), COROSYNC (172.16.1.x/24) and VMBR0...
