Original fix proposed by Stanislav German-Evtushenko (giner) CPC Ubuntu cloud images default to enabling a serial console connection via the kernel commandline option `console=ttyS0`. Many clouds support the serial connection, and utilize it for debugging purposes. Virtualbox supports the serial connection as well. In Bionic and earlier images, Vagrant boxes created a serial log file in the directory of the Vagrantfile by default. However this is not standard behaviour for Vagrant images, and so it was removed in Eoan onwards. Starting in Eoan, there were reports of image booting slowdown (1874453 is a single example). After testing, it was determined that the serial connection starting, without a device attached, was the cause of the slow down. However, we did not want to revert to the old functionality of creating a file. Much thanks to <giner> for providing the Ruby syntax for sending to File::NULL. This option will not create a local file, however, the default Vagrantfile configuration is overwritable via a users Vagrantfile. The original syntax for creating a file local to the users Vagrantfile has been included as an example.
