VirtualBox reports VERR_ACCESS_DENIED on disk image

[HunterZ]

A VM that I'm able to launch just fine via the GUI won't launch via VBoxVmService. I get the following in the VirtualBox log:

You are using some shared folder on another server. I suspect this might be related to access issue. The share might not be ready when the service starts or not accessible by the user service runs as.
