я только поставил the VirtIO-Win ISO.
Currently Proxmox VE supports 2 types of cloud-init images: nocloud v1 (the default and recommended type), and configdrive v2. Most images of major distributions should fork fine with the default. In the future, nocloud v2 may be supported as well which should have a more robust way to configure network devices as it does not depend on specific device names (see the Networking section below).
The configdrive v2 variant may work for windows guests using cloudbase-init, but this is not officially supported.
