Packer - can't lock file '/var/lock/qemu-server/lock-

[steveDecot]

Hi everyone !

I' ve issues with packer and my proxmox cluster.

I would like create a Rocky Linux 9.4 template for starting. After that the idea is to use Terraform with this template.
I'm stuck on packer step.
This is the permissions through my token

Code:

pveum acl list | grep -i "packergrp"
/      | Administrator | group | packergrp | 1 |

My packer version
Code:

packer --version
Packer v1.11.2


Packer use the token for user "packer" who is member of "packergrp" .
This is my hcl code

Code:

packer {
  required_plugins {
    proxmox = {
      version = ">= 1.2.1"
      source  = "github.com/hashicorp/proxmox"
    }
  }
}

  type = string

  sensitive = true
}

}

  type = string
}

  }

}

build {
  name    = "rocky-linux-with-ks"
  sources = [
    "source.proxmox.rocky-linux"
  ]
}

I've my kickstart file in http dir and my variables.pkvars.hcl.
Everything is fine exept at the end, especially on stopping VM for create the template.

On pve side I've this

Code:

trying to acquire lock...
TASK ERROR: can't lock file '/var/lock/qemu-server/lock-104.conf' - got timeout

and on packer side

Code:

rocky-linux-with-ks.proxmox.rocky-linux: output will be in this color.

I tried

To use a different id : same issue
To update my repo on packer : same
When I tested the code, I had some issues and I stopped many time the code ( CTRL + C ) and the machines have been poweroff, even if my linux work .

I think the problem is on the templating phase.
I check the new version of code here : https://github.com/hashicorp/packer-plugin-proxmox/blob/main/docs/builders/iso.mdx . But elements are missing ( like
iso_storage_pool , umount_iso ... )
Do you have any ideas please ?

[steveDecot]

Anyone can help me please ?

@steveDecot this could be that the QEMU agent (package qemu-guest-agent) isn't installed and running on the build guest. VM shutdowns in Proxmox rely on the agent to initiate a soft shutdown of the OS rather than a Power Off (hard stop).

A Ctrl+C during a packer build executes a Power Off (hard stop) which doesn't wait for the OS to signal that it's shut down.

[steveDecot]

@mpywell Hi ! Thx for answer me ! :) I've this on my ks file

`%post
dnf install -y qemu-guest-agent
systemctl enable qemu-guest-agent
%end

Reboot after the installation is complete.

--eject attempt to eject the media before rebooting.

reboot --eject`

The machine reboot correctly and I check the logs

I think it's my nic card is not correctly enabled or qemu issues .

I will try and tell you

[steveDecot]

So I tried, qemu was installed through ksfile.cfg correctly.
I've this

Same error.
Qemu seems ok. Why I've this lock file ?
From console remote, I see this

[steveDecot]

Hi !

I found the problem,

In my ks.cfg file, I disable acpi ! --> acpi=off

This command create my issue, even the shutdown command was stuck in the same way than packer

I remove them and it's work fine !

Have nice day !
