Thanks for the link superman...

I solved the issue by buying a large pendrive and...

1. Installed KNOPPIX on it and created a 1GB persistence file just to install VirtualBox and keep any changes done in the settings (language, keyboard etc).
2. Booted KNOPPIX on the USB and repartitioned the pendrive creating a large partition formatted as exFAT. I used this partition to host my vdi and vhd files.

Since pendrive prices are relatively cheap compared to their sizes, it would not be worth it to remaster KNOPPIX and risking breaking packages.

Thanks to all for your help in this.
