Hi, there! First of all, great work! I'm glad to see that Nyx mode is finally available in libAFL :-) I've just tested the patches, and it seems like something...

Does this issue still occur with the latest commit of [Nyx-Testing](https://github.com/nyx-fuzz/Nyx-Testing)?

The current status regarding vmware backdoor io hypercalls is as follows: -> We already use this interface in case KVM-Nyx is not installed, and the user does not need Intel...
