<br>
what host-OS do you use? I tried the same with Linux-VM (with RT-Preempt
kernel) and Windows-host, got the same result. You may try following:<br>
* Use a RT-Preempt kernel in the VM<br>
* Use ethercat-capable network-drivers in the VM (e1000 or maybe e1000e should
work with Oracle VM Virtualbox)<br>
* Use a Linux Host with RT-Preempt kernel and set the VM to realtime priority
(98)<br>
I've never tried this before, but this might reduce issues.<br>
