Ubuntu – Intel Simics: VMP Kernel Installation fails (linux 22.04)

When I try to build/install the VMP kernel I receive the following error:

Setting up your system for Simics VMP
================================================

This step will be performed with root privilege through sudo:

  - Loading of the vmxmon kernel module.

Unless this script is run as root, you will be prompted for the
root password during those steps.

    Your version of the Linux kernel is not yet supported but if you can downgrade to before 6.5 it should work. We have an internal request to support more recent versions. Not ETA at this time.

    In general this is a problem with new kernel versions, the API is not stable.

    I run Simics on Fedora 37 on an Intel i9-13900K computer.
    It failed to load VMP as mentioned above with a 6.5 kernel.
    So I built a 6.1.63 kernel and now it passes that step and
    builds vmxmon successfully, but after that it hangs.

    Got this error when starting a Simics machine.
    [board0.mb.cpu0.core[0][0] info] VMP disabled. Failed to open device.
