Add motherboard information to the VirtualBox docs
Reported by user:
The default motherboard on VirtualBox (PIIX3) can sometimes be unable to boot.
The user has found that changing it to ICH9 Tails boots correctly.
Maybe we can add that to the instructions for VirtualBox (https://tails.boum.org/doc/advanced_topics/virtualization/virtualbox/)?
