I know there is some huddlihut with plymouth and virtualbox vm - I don’t know what it is but I know what workaround to apply.
- Restart your vm - and hit Esc to enter too Grub menu.
- Edit your command and remove
quiet
,splash
andudev.log_priority=3
- press F10 to boot the vm. - Edit your /etc/default/grub and edit the command to remove the above arguments.
- Save and rebuild your grub config
grub-mkconfig -o /boot/grub/grub.cfg
