The virtual disk works just like a hard drive. If you create a 80GB hard drive it reports it to the guest OS as a 80GB hard drive. The "don't allocate the entire disk now" message is about how the host OS creates the virtual disk file. If you don't allocate it up front you end up with a sparse file. du and df commands will show the space actually used. ls will show you the actual file size which would be 80GB. Ryan
