How to disable PS/2 input devices?

[nobinson1021]

Describe the Issue

Hello.

I am trying to pass through a USB device (iPhone), but it is conflicting with the default PS/2 mouse and keyboard. I am using ULTMOS v0.13.3.

Here is what I have tried to solve this:

1. I tried removing the PS/2 devices from virt-manager, but they are automatically re-added.

2. I tried editing the XML with 'virsh edit' to add '' inside the '' block.

This causes a persistent XML validation error: "Extra element features in interleave". I have tried different element orders and even replacing the entire features block with known-good configurations, but the validation always fails.

Could you please provide the correct XML syntax to permanently disable the PS/2 controller/devices for ULTMOS v0.13.3?

Thank you.

Reproduce the Issue

1. I tried to remove the PS/2 mouse and keyboard from the VM's hardware in virt-manager.

2. The devices are automatically re-added.

3. I tried to edit the XML with 'virsh edit' to add '<i8042 present='no'/

' inside the '' block.

4. This causes an XML validation error: "Extra element features in interleave".

Expectation

I expect to find a way to permanently disable the PS/2 input devices so they do not conflict with my USB devices. I need to know the correct XML syntax for this project.
