@giner, I tried setting the uart1 to "disconnected" in the past, but then the VM on Windows slows down to a halt.

@jchittum
After investigating it, I saw that indeed the OVF file contains "/dev/null". I used packer in the process, which basically does if I understand correctly creates a VM based on the Ubuntu vagrant box, modifies the VM, and then uses vagrant package to generate a new box. Therefore, I'm not sure this is an issue with Ubuntu.

If I just try to run the Ubuntu VM on Windows, I see that `File::NULL` is translated into `NUL`, and the VM seems to be working fine.

I think I'll try to include the line `vb.customize [ "modifyvm", :id, "--uartmode1", "file", File::NULL ]` in the packer-generated vagrantfile somehow.
