Proxmox 6.0 - migration issue

[PiotrD]

Hi, I am trying to do an online/offline migration of the VM, and I get an error when I have a cloud-init device attached.



I read this thread https://forum.proxmox.com/threads/vm-live-migration-fails-when-cloud-init-image-is-attached.44485/ and I thought this issue was fixed. Is it suppose to be like this ?

# pveversion
pve-manager/6.0-7/28984024 (running kernel: 5.0.21-2-pve)

Just to make it worse, I am not able to remove Cloud init Device from a VM, without stoping it. So this as a workaround is pretty terrible.

Ok, it seems like this is a bug only in GUI. I was able to do this from console, but there is a small error.

It was unable to remove this cloudinit image from a source node. I found vm-191-cloudinit image and removed it manually.
