It is my understanding that FreeBSD doesn't allow using part of a disk,
but grabs the entire disk.  That means that VirtualBox can't use
partitions on a disk that any other partitions are being used by
anything else, including FreeBSD itself.  Am I wrong about this?  I use
VirtualBox using vdmk for an entire disk, but I have never been able to
share with anything else.
