See the attached screenshot of the settings. Serial port mode is set to Host device. After starting virtual machine it hangs on "Starting virtual machine" window. Tested on current test build 101778.
Maybe the problem is related to this: the http://stackoverflow.com/questions/18821811/serial-port-hangs The port should be opened in O_NONBLOCK mode.

Don't use the tty.* device but the one starting with cu. See for an explanation of the difference here and here. It should be possible to make it work correctly with the tty device by using O_NONBLOCK and then setting CLOCAL but that might break other devices which will use the DTR line for something else because setting CLOCAL will cause DTR to be ignored. I'll close this for now, please reopen if you still experience the hangs when using the /dev/cu.* device.
