Hi,

I'm facing an issue with migrating a VM from Proxmox version 7.4 to version 8. When the CloudInit drive is included in my conf,
Code: 
ide2: local:100/vm-100-cloudinit.qcow2,media=cdrom

I encounter the following error:

Code: 
2025-03-01 13:31:37 ERROR: migration aborted (duration 00:00:01): error - tunnel command '{"with_snapshots":1,"format":"qcow2","volname":"vm-100-cloudinit.qcow2","allow_rename":"1","storage":"local","export_formats":"qcow2+size","snapshot":null,"cmd":"disk-import","migration_snapshot":""}' failed - failed to handle 'disk-import' command - 400 Parameter verification failed.


If I remove the CloudInit drive, the migration completes successfully to version 8.3. However, migrations from version 7.4 to 7.4 work without any issues even with the CloudInit drive.

Code: 
The source Proxmox version is:
proxmox-ve: 7.4-1 (running kernel: 5.15.152-1-pve)
pve-manager: 7.4-18 (running version: 7.4-18/b1f94095)
pve-kernel-5.15: 7.4-13
pve-kernel-5.15.152-1-pve: 5.15.152-1


The destination Proxmox version is:
proxmox-ve: 8.3.0 (running kernel: 6.8.12-8-pve)
pve-manager: 8.3.3 (running version: 8.3.3/f157a38b211595d6)
proxmox-kernel-helper: 8.1.0
proxmox-kernel-6.8: 6.8.12-8
proxmox-kernel-6.8.12-8-pve-signed: 6.8.12-8


I am looking for assistance in resolving this

Hi!

Is this a migration within a cluster or a remote migration between two mixed version PVE nodes? Could you post the full command and/or output of the migration? Either way, we discourage the mixed usage of different major versions of Proxmox VE, especially since Proxmox VE 7 is end-of-life since July 2024.
