Unable to create qcow2 format disks

[sudomas]

Packer creates the VM always with raw disks only, no matter what disk format is defined in disks block. Here's my disk configuration.

disks {
storage_pool = var.isoStore
storage_pool_type = "directory"
type = "virtio"
disk_size = var.diskSize
cache_mode = "none"
format = "qcow2"
}

It creates VM with a raw disk always. I tried changing the disk type to iscsi, format to qcow etc. but that did not help.

I use the Packer version 1.7.3 on Ubuntu 20.04 and trying to create a template of Ubuntu 20.04.

I have the same issue on Ubuntu 20.04 with Packer 1.7.4, using the following configuration block:

disks {
  type              = "virtio"
  disk_size         = "10G"
  storage_pool      = "local"
  storage_pool_type = "directory"
  format            = "qcow2"
}

Same issue here with Packer 1.7.6, I'm building a VM based off of a Peakflow ISO image with the following disk settings:

  disks {
    disk_size         = "120G"
    storage_pool      = "gluster-volume"
    storage_pool_type = "directory"
    type              = "scsi"
    format            = "qcow2"
  }

The only workaround I found is to live change the disk format while the OS is installing, before Packer converts it to a template. I tried with storage_pool_type zfspool and lvm getting the same result.

Fixed with Telmate/proxmox-api-go@062fd1a

Hello, is there any plan to bump github.com/Telmate/proxmox-api-go to v0.0.0-20220129131641-6909b62b8cf0 (I'm not aware at all about your release model)? Sounds like the fix is working

[humberto-garza]

We are also experiencing this issue with Packer 1.7.10

[Pumba98]

#60 fixed this.
Could you release a new version please? @azr

[Pumba98]

works fine now with 1.0.5, thanks

[theblop]

@Pumba98 Are you sure? I upgraded to 1.0.5 and it still ignores the format value and produces only raw disks...

[Pumba98]

yes, I am @theblop . I changed the version in my required_plugins to >= 1.0.5 and run packer init.
Before the files were .raw now they are .qcow2 and it fixed my problems after cloning them with terraform

[theblop]

@Pumba98 that's weird... I upgraded too and I still get a raw disk...

packer {
  required_plugins {
    proxmox = {
      version = ">= 1.0.5"
      source = "github.com/hashicorp/proxmox"
    }
}

source "proxmox-iso" "vm" {
  ...
  vm_id = 99999
  disks {
    disk_size         = "80G"
    format            = "qcow2"
    storage_pool      = var.proxmox.storage_pool
    storage_pool_type = var.proxmox.storage_pool_type
    type              = "scsi"
  }
  ...
}

After the build I get a raw image:

root@ebsifactory:~# pvesh get /nodes/proxmox/qemu/99999/config
...
│ scsi0       │ storage:99999/base-99999-disk-0.raw,iothread=0,size=80G │

[Pumba98]

@theblop sorry, I have no idea what could be wrong.
Double check with packer plugins installed (new in packer 1.8) that you got the right proxmox plugin version. Everything else lgtm

[f-bn]

Can confirm it works on my side (Packer 1.8.0). Great !

I'm still experiencing the same issue even with plugin version 1.0.5:

• Packer config file:

packer {
  required_plugins {
    proxmox = {
      version = ">= 1.0.5"
      source  = "github.com/hashicorp/proxmox"
    }
  }
}


...
  disks {
    disk_size         = "120G"
    storage_pool      = "efs"
    storage_pool_type = "directory"
    type              = "scsi"
    format            = "qcow2"
  }
...

• Packer and plugin version:

$ packer plugins installed
/home/dbuenoparedes/.packer.d/plugins/github.com/hashicorp/proxmox/packer-plugin-proxmox_v1.0.5_x5.0_linux_amd64
$ packer version

• Proxmox VM disk info:

[humberto-garza]

@ruskofd, could you confirm that packer 1.8.0 does work for you?
I tested 1.8.0 and the issue was still there
But I confirmed that with 1.8.1 the problem is fixed!
@dbuenoparedes, could you confirm this?

[mm3906078]

my packer version is 1.8.2 and I have the same issue

• Packer config file:

disks {
   disk_size = "20G"
   format = "qcow2"
   storage_pool = "Backup"
   storage_pool_type = "lvm"
   type = "virtio"
}

• Proxmox storage.cfg

lvmthin: Backup
        thinpool Backup
        vgname Backup
        content images,rootdir
        nodes pve

The same config works with raw just don't work with qcow2

[andrei-matei]

Same issue for me, I am using Packer 1.8.3 and proxmox 1.0.8.

[modem7]

No issues currently for me:

• Packer config file:

    disks {
        disk_size = "15G"
        format = "qcow2"
        storage_pool = "Proxmox"
        storage_pool_type = "directory"
        type = "scsi"
        cache_mode = "writethrough"
        io_thread = true
    }

• Proxmox storage.cfg

dir: Proxmox
        path /mnt/prox
        content images,snippets,rootdir,vztmpl,iso
        prune-backups keep-all=1
