Running Virtual Box (5.0.0) on an iMac and trying to install Snow Leopard. I get all the way up to the screen to install onto a disk, and there are no disks displayed.

If I go into Disk Utility, I can see the VBOX HARDDISK, which is "unformatted". So I think, well, OK, that's weird, but I'll setup a partition and see what happens."

So, that works, but why does this have to be done manually or why is there no warning on this when setting up an OS X VM?

(normally I just use VB to run old Windows versions, but thought this might be a lark...)

One reason would be because OSX is not a supported guest but it is still possible to create one. There are multiple posts on how to install an OSX guest on the forum had you looked.

What do you mean "is not a supported guest"? It's right there in the list of Oses to install with Windows and others, and even has a sub-choice of which version.

There's no indication in the software that I need to go elsewhere for directions on how to install OS X or that OS X is in any way different that, say, Windows 8.1/

From the user manual…

Starting with version 3.2, VirtualBox has experimental support for Mac OS X guests. This allows you to install and execute unmodified versions of Mac OS X on supported host hardware.

The Mac OS X installer expects the harddisk to be partitioned so when it does not offer a selection, you have to launch the Disk Utility from the “Tools” menu and partition the hard disk. Then close the Disk Utility and proceed with the installation.

In addition, as Mac OS X support in VirtualBox is currently still experimental, please refer also to chapter 14, Known limitations, page 250.
