Actually, if this is a Linux or Unix system, you can run the VM as root. Then simply revoke access to the device node in /dev from everyone. Of course root will still be able to access it, but other users will not be able to mount it at all. The only drawback to this approach is that you would have to run the VM using the sudo command with the root password.
Ok, it was a bit too easy to work :)
As mounting is only allowed as root except for those devices that are listed in fstab (and this device will never be listed there if I have anything to say on the matter) I'd already be sudo to even attempt mounting it; therefore this would not work (as I'd be allowed to do that).
This means that I'll just need to steer clear of the following path of thought: "hmm... an unmounted block device... what the... umm... I'll just mount it and see what it has eaten" ... "hmm... what the *heck* just happened to the client's production db server?"

There is no way to do this. If the drive is plugged, the OS can see it (otherwise, the VM wouldn;t be able to use it).
