There is a problem with virtualizor install script.
Tested on fresh debian 12 with proxmox.
First problem:
Installer script try to install libsepol1-dev package but it is not available. New package name is libsepol-dev and after manual installation script is working ok.
Second problem:
Missing kpartx
Third problem:
Missing throttle package
Missing kpartx and throttle will cause errors because dd cant copy system image to vm disk.
