I set my virtual box 2.1.4 on a linux host Granular 1.0
the virtual os is XPPro

to expand.. Not fixed size.. I lately tried to install something and I get this message.
-----------------------------
Host system reported that the file size limit of the host file system has been exceeded. VM execution is suspended. You need to move your virtual hard disk to a filesystem which allows bigger files. Error ID: DevATA_FILETOOBIG Severity: Non-Fatal Error

So what is your problem? The log message tells you everything...

Host system reported that the file size limit of the host file system has been exceeded.

That says it all, you're letting the file grow beyond the max file size the filesystem can handle. This is a common error when users dualboot between Windows and Linux, they use a FAT32 partition for data sharing. But FAT32 is limited to 4 GB files. Use NTFS instead. Ntfs-3g is stable enough. I have several drives in my computer, all NTFS and run Linux as main OS, no issues with it.
