I apologize if this has been asked, I couldn't find it. I'm running Ubuntu 12.04, and I have a VirtualBox VM that starts headless when the machine boots up. For some reason, when it first tries to run, VirtualBox complains that it's can't find the virtual disk (which is on another drive) - once I open the directory manually, I can run the VM and everything is fine.
Why doesn't Ubuntu see the other drive at first? Has anyone encountered this?
