VirtualBox haos_ova-8.4.vdi won't boot

Installation
#1

Running Windows 11, tried latest VirtualBox and an earlier version (6.1.30), same results.

Steps to reproduce:

  1. Download the vdi and follow the instructions here: Windows - Home Assistant
  2. Power on the VM
  3. Observe it gets stuck in a boot loop trying to load Slot A, then drops into UEFI interactive shell ad, and back to Booting slot A ad infinitum
#2

In case anyone else runs into this, make sure you bump the # of Processors up to 2. The default is 1 and you must switch it to 2 or the VM won’t boot.
