Hello everybody, I'm new member of twinControls and this my first Topic. I hope to be clear and using the right spirt of this Forum.

I'm trying to use TwinCAT on a Virtual Machine created with Virtual Box, but when I try to put TC in Run mode I get the following errors:

The first with the Previrtualization Interface set to "Hyper-V" and the second error when it is set to "None" (in the Virtual Box Settings --> System).
I tried already many suggestion is possible to find on the Network, like: deactivation of Hyper-V, Virtual Machine Platform and Windows Hypervision Platform on the Host system, setting of shared CPUs leaving one Insulated and putting it as Default, running as administrator win8settick, etc...

From the second Error, I though that the Guest machine is not able to find an active virtualization (Intel VT-x) by nested virtualization.

Indeed in the Setting of VM (in System --> Processor) the setting of "Nested VT-x/AMD-V is not selectable, and I was not able to make the selection active.

Here my system parameters:

Host machine:

HP ZBook Power with processor Intel Ultra 9 185H

OS Win11 Pro

Virtualization Technology and Intel VT-x in the BIOS are active

Virtual Box version 7.2.0 r170228

Guest machine:

OS Win 10 Pro

TwinCAT 3.1 build 4024.67

In the following screenshot all the setting of the Virtual Machine:

I decided to use a virtual machine, thinking was a good idea to start using TwinCAT and perform testing and prototyping in a saparated part of my PC. I wanted in the end install TwinCAT directly in the win11 real machine , but I'm very worry these problem could happen also there.

I'm really close to be disparate, and I hope someone could know a solution for this issue.
I thank you in advance for every help and apologize if my post is not orthodox.

With best regards,

Simone
