The "Copy-On-Write" nature means the file only takes up as much space as the data actually written to it, even if the virtual disk is set to a larger size (e.g., a 60GB disk might only be a 15GB file).

First, ensure QEMU is installed on your system. If you're on Ubuntu or a similar Linux distribution, you can install it using:

If you want to import your newly generated image directly into a Proxmox cluster, move the file to your Proxmox node and issue the following command via SSH:

After optimization, trim the QCOW2 image from the host:

If your QCOW2 file footprint matches its maximum virtual size (e.g., occupies 40 GB on the host even though Windows claims to only use 15 GB internally), zero-blocks are scattering across the image.
