Sorry if this kind of question isn't allowed here, but I'm at my wit's end. VB randomly started launching on startup about 2 weeks ago (on EndeavourOS) and I can't figure out why. There's no shortcut in ~/config/autostart, it isn't in the KDE startup apps list, and I can't find anything virtualbox-related with systemctl either. There's also no setting in the VB app itself. WTF?
To successfully automate a VirtualBox VM to start at boot time, we must ensure we’re running VirtualBox version 5 and above.
By default, after installing VirtualBox, the vboxautostart-service unit file should exist in the /etc/systemd/system/ directory.
Alternatively, for systems missing the vboxautostart service, we can create a custom systemd unit file that will contain our configurations to run VirtualBox on boot. systemd is a system and service manager for most Linux-based OSes.
Didn't see you mention the autostart-service, and the article is recent enough that maybe it was added as part of an update?
