Hello.
For getting into Linux CNC, I built a small test setup (mainly power supply, 7i76E, 7i74 and 7i73... planning to add additional hardware later).
As this is just for testing purposes only, I run Debian 11 64bit in a VM (VM Player). PREEMPT_RT kernel is installed (uname -a output: "5.10.0-11-rt-amd64 #1 SMP PREEMPT_RT Debian 5.10.92-1 (2022-01-18) x86_64 GNU/Linux"). I built Linux CNC from master branch (make & sudo make setuid) and run it directly from bin dir.
I am able to ping 7i76E. Also I can access the 7i76E using mesaflash:
I successfully flashed "7i76e_7i76x1_7i74x1D.bit" from support files provided on mesa website.
Now, I try to run halrun with these commands:
I wonder what I'm doing wrong here? Is it even possible to run this in a VM or is phyiscal hardware required (even for testing purposes)?
After two days of research and multiple times of reinstalling everything... I hope to find some assitance here.

I don't think you can make the hm2 driver work without real time response from the hardware

Thank you. Will try on/with real hardware in next days.

But, you can always boot into a Live session from USB and work from there, just keep in mind to save changes to a hard drive or another USB.
You can also boot from USB and use an existing configuration, make a new configuration and save it, etc etc.

The short answer is no, not for actually controlling a machine.Is it even possible to run this in a VM ....

I tested this today on real hardware. Works without any issue so far.
