# RETIRED. Kept for reference only.
#
# Proxmox imports OVA/OVF natively now, via a storage with the "import" content
# type: upload the .ova there and use Create VM > Import, or `qm importovf`.
# The built-in path handles disk format conversion per storage type, which this
# script did not.
#
# Known bug, left unfixed since the script is retired: importdisk is called with
# --format qcow2 unconditionally, which fails on ZFS and LVM-thin storages that
# do not take a format argument.
