Is it possible to import a qcow2 file and use the virtual size of the image?

[joshmcorreia]

For example, I have the following file:

root@proxmoxjoshtest:/var/lib/vz/template/iso# qemu-img info joshtest.img
image: joshtest.img
file format: qcow2
virtual size: 20 GiB (21484431360 bytes)
disk size: 1.87 GiB
cluster_size: 65536
Format specific information:
    compat: 0.10
    compression type: zlib
    refcount bits: 16
Child node '/file':
    filename: joshtest.img
    protocol type: file
    file length: 1.87 GiB (2007833600 bytes)
    disk size: 1.87 GiB

When I try to import it without specifying a disk size, the provider defaults to 8GB instead of using the virtual size. This is the error that's printed out:

│ Error: resizing disk: error waiting for VM disk resize: All attempts fail:
│ #1: task "UPID:proxmoxjoshtest:0003A41F:008785D8:67085B4E:resize:101:terraform@pve!provider:" failed to complete with exit code: shrinking disks is not supported

If it helps, here's my .tf file:

resource "proxmox_virtual_environment_vm" "joshtest1" {
  name      = "joshtest1"
  node_name = "proxmoxjoshtest"
  vm_id     = 101

  memory {
    dedicated = 8192
    # set floating equal to the dedicated field above to enable ballooning
    floating = 8192
  }
  # "Processors" in the UI
  cpu {
    sockets = 2
    cores   = 1
    type    = "Westmere"
  }
  bios = "seabios"
  # "Display" in the UI
  vga {
    memory = 16
    type   = "std"
  }
  # "SCSI Controller" in the UI
  scsi_hardware = "lsi"
  # "Hard Disk" in the UI
  disk {
    backup       = false
    cache        = "writeback"
    datastore_id = "local-lvm"
    discard      = "ignore"
    file_id      = "local:iso/joshtest.img"
    interface = "sata0"
    iothread  = true
    ssd       = false
  }
  network_device {
    bridge = "vmbr0"
  }

  on_boot = false
  operating_system {
    type = "l26"
  }
}

Is it possible to import a qcow2 file and use the virtual size of the image? I know that I can manually give it the size but wanted to see if using the virtual size is supported. Thanks!

Hi @joshmcorreia
That’s not possible right now since the disk size has to be set in the config (or provider will apply default 8Gb). But we could probably add this feature down the road.
