Ventura and proxmox 7: installer complete, first boot ok, second boot just apple logo

[pasztorl]

Hi,

I've just installed Ventura using this docs: https://www.nicksherlock.com/2022/10/installing-macos-13-ventura-on-proxmox/

The instruction is clear and the install went flawlessly and I got the MacOS desktop. Then changed background settings disabled the sleep / hibernate and added some other users. After restart Opencore loads, selected the Main boot device then I just get an apple logo.
If i hit ctrl+v I can see this:

What does it means, and how can I manage to boot? Thanks!
