I have several ubuntu guests inside a Mac OS X virtualbox host. When I start them, about half of the time they correctly boot and get to their login screens/start all their services. The other half of the time, they sit waiting for me to choose an OS. This is fine when I'm sitting in front of them, but I'd like the VMs to automatically boot when the machine starts.
It's worth noting that the same problem doesn't seem to happen if I do a reboot from within the guest OS.
What I've tried:
I've tried uncommenting
GRUB_HIDDEN_TIMEOUT and running
update-grub, this makes the guest OS boot correctly more often, but doesn't fix the problem. Booting them headlessly doesn't help either.
Where they get stuck:
