Nixos-generate for proxmox stuck on "Booting the kernel"

Help
1

I want to deploy a nixos configuration to proxmox.
It gets stuck on “Booting the kernel”.

configuration.nix (empty)
{ config, pkgs, ... }: {}

What i tried (details like filenames and hosts may differ):

# Build
nixos-generate -f proxmox -c configuration.nix

# Transfer
scp vzdump-qemu-nixos-24.11.717703.5b35d248e920.vma.zst root@host:~

# On proxmox
unzstd vzdump-qemu-nixos-24.11.717703.5b35d248e920.vma.zst

vma extract ./vzdump-qemu-nixos-24.11.717703.5b35d248e920.vma ./nixos

qm importdisk 101 nixos/disk-drive-virtio0.raw local-lvm

In Gui:
Hardware → unused disk → doubleclick
options → bootoptions → enable drive

Thanks for any tipps.

Fixed by adding missing drivers:
imports = [
(modulesPath + “/profiles/qemu-guest.nix”)
];
