PVE 6: proxmox host got cloud-init from a VM?

[pukkita]

Hello,

Recently installed a PVE 6.0 cluster with three Supermicro X9DRi-TLN4+.

I tested deploying a VM from ubuntu 18 cloud-init image, following https://pve.proxmox.com/wiki/Cloud-Init_Support

I also (mistakenly, but thought it would be harmless) installed cloud-init on proxmox host itself.

After rebooting proxmox, it seems something got mixed up:

- if you ssh to previous proxmox management ip, credentials work but you end up logged inside the ubuntu cloud-init VM.
- No proxmox GUI listening on 8006
- Server console (X9DRi-TLN4+ IPMI) displays the ubuntu VM prompt (wtf?)

I've removed cloud-init from proxmox host, added cloud-init=disabled to kernel command line and created /etc/cloud/cloud-init.disabled, to no avail.

I'm new to cloud-init, guess proxmox has been mistakenly "cloud-init provisioned"?? Is there any way to undo this apart from reinstalling?

Can attach any relevant logs, a little confused as to which ones however.

You'll have to set the right hostname (/etc/hostname), fix your /etc/hosts file and perhaps also the /etc/network/interfaces file.

Hello, the same thing happened to me, but I can't figure out how to fix it. Can you help me?

Uninstall cloud-init first: apt purge cloud-init
Then set your hostname again in /etc/hostname to the correct one.
Check your network config in /etc/network/interfaces.
Then set the correct IP and hostname in /etc/hosts. It should look like this:

<IP> <hostname>.<domain> <hostname>
