**Problem:** In my unsuccessful attempt to complete the cross vm connectors tutorial, [1](https://docs.sel4.systems/Tutorials/camkes-vm-crossvm.html), I discovered [2](https://github.com/seL4/sel4-tutorials/issues/49). I am now trying to use [3](https://github.com/seL4/camkes-vm-examples/tree/master/apps) with the new connection module which I thought would expose the dataport device to the VM but the corresponding device does not exist in */dev*. I have confirmed that the module is loaded with *lsmod* in the guest. The original tutorial uses an executable *dataport_init*, which is called from the *camkes_init* script. I assume that this executable would provide the setup for the dataport, however the executable *dataport_init* is not in the *default_buildroot_rootfs.cpio* (note: *consumes_event_init* and *emits_event_init* do exist in the rootfs archive) or as a project anywhere in the project files to be overlayed. Because I could not find this executable in the arm example, I assumed that the connection module aided in the dataport initialization process.

**Questions:** 1. Where and how is the dataport device (*/dev/uio0* in this case) exposed/initialized so that read/write can occur? 2. Is there an up-to-date version of the Cross VM Connectors tutorial for x86?

I have limited knowledge on this and I may not even be asking the right questions -- therefore any feed back and responses are welcome, thanks.
