I'm running into the same issue with Arch. `gem pristine ruby-libvirt --version 0.7.0` doesn't seem to help.

I'll update the PR soon and we can merge :)

Rebased, fixed LED pin. Not sure the default version includes https://github.com/platformio/platform-espressif32/pull/736

@jesserockz can you please take a look?
