migration

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...

My organisation is about to migrate circa 100 VMs, from a bunch of libvirt machines to a brand new PVE cluster. We found a few pointers about the migration process, but it requires a lot of manual intervention. Is there a way of automatize the process as much as possible ?

I am trying to migrate a physical windows test server to Proxmox. These are the steps so far: 1. used Disk2vhd and created a vhd file on a USB Drive. 2. Connected the USB to a Ubuntu machine and ran qemu-img convert -p -f vpc -O qcow2 WIN-4GSGQMJ1U8A.VHD WIN-4GSGQMJ1U8A.qcow2 So, I now...

Hello, I plan to upgrade my hardware with new cpu, motherboard and ssd. Actually I have an old i7 6700k and I struggle with. My upgrade will be a ryzen 9 7900 and enterprise class SSD (Kingston DC600). My current SSD have a partition for OS and for VM. My plan is to move VM to an other drive...

Hi all, I am on Proxmox 9.0.10, with 2 servers in my cluster. I have a relatively large VM disk, which fails on live migration every time. The initiating HV is LVM and the destination is ZFS. I have attached the full migration log, but the error is mainly channel 4: open failed: connect...

[GUIDE] High-Speed, Low-Downtime ESXi to Proxmox Migration via NFS Hello everyone, I wanted to share a migration method I've been using to move VMs from ESXi to Proxmox. This process avoids the common performance bottlenecks of the built-in importer and the storage/downtime requirements of...

Hi. I've recently added an LVM thick storage to my PVE cluster which is a LUN shared between 4 of 5 nodes and everything works just fine except VM migration. I migrated VM from the 5th node which only has local storage to different node and shared LVM storage. Now I can't migrate it back. When...

Hi ! I have a 3 node cluster on Proxmox and one of the Hosts has some issues I couldn't identify till now. To have my VM save I wanted to put it onto a dedicated (external) NFS where the VM is hosted so that I can easily move the VM between by cluster. If I do the migration between the 2 "good"...

Is it possible to define a migration type per VM so that it's always applied to that VM? I have some VM's that I always need to be offline migrated for a few reasons (one is for example a connected PCI device, which is available on all nodes). For this VM's I would like to specify that, if they...

Hello all! This is the first time I've used the migrate feature. I have two nodes in a cluster, and I was looking to move all containers from Node 1 to Node 2. I used the bulk migration option, and it migrated more than half of the containers that I have. However, for some reason, there are a...
