Virtual machine crashes when trying attach host LPT

Reported by: alexnnn Owned by:
Component: other Version: VirtualBox-7.0.14

Guest type: other Host type: Windows

Description (last modified by alexnnn)

I run VirtualBox on the Windows 11 host. My host machine has a LPT port which I need to have attached to the VM. I set it up with the following commands

VBoxManage modifyvm <VMname> --lptmode1 <host LPT device name>
VBoxManage modifyvm <VMname> --lpt1 0x378 7

With VirtualBox 6 it worked fine. But since I moved to the version 7, VM crashes during boot. It happens in the very beginning of the boot process, before the VirtualBox logo appears on the screen, and seems not to depend on the VM type. I created a new VM with the default settings, without attaching any hard drives and without installing any OS, and got the same result. Here's a log file from this VM.

The parallel port passthrough code on Windows host was disabled with VirtualBox 7.0.0. Since then it gives this not so great diagnostics. It was never officially supported...
