+Do not expect SIMtrace2 to work in VMs
+--------------------------------------
+
+We only support running SIMtrace2 together with a Linux system running
+"bare iron" on actual hardware (x86, x86_64, arm, ...).  **using VMs
+with USB pass-through for things with critical timing like SIMtrace2 is
+calling for trouble** and we will not accept related bug reports or
+support you if you do.  If you still want to use VMs: Feel free to do
+so, but understand that it's unsupported and you are on your own.
