Comment 16 for bug 1473527

This can also be configured to pass by having virtualbox provide a serial console connect:

1. select image on Left, right click and choose Settings, or hit ctrl+s
2. Choose Serial Ports
3. Enable Port 1 as follows:
  a. Enable
  b. COM1
  c. IRQ: 4
  d. I/O Port: 0x3F8
  e. Port Mode: Raw File
  f. Path/Address: <INSERT PATH AND FILE NAME>

After connecting this, I observed that cloud-init finished all parts successfully.
