Hi,

You miss a files, you should have 2 files :
  • Prod1g5_1-flat.vmdk
  • Prod1g5_1.vmdk
Put the 2 files in the same directory and try to import again.

Here, the idea is to import the disk images directly with the qm disk import command. Proxmox VE needs to be able to access the *.vmdk and *-flat.vmdk files
Click to expand...
