Public bug reported: .VirtualBox 5 Ubuntu 16.04 Xenial Final 20160419 I assume this bug is similar to bug#1447038 except this is not a live session but a post install reboot problem. Reboot after install does not work or freezes Virtualbox, requiring a manual shutdown of Virtualbox, then a manual start of the newly installed Ubuntu image.
