Script to resize ova cloud image using VBoxManage
Cloud images usually are built with minimal disk space requirements. This script uses VBoxManage to change its size for use with VirtualBox.
resize_ova.sh /path/to/ova [ new-disk-size ]
1st arg location to ova image
2nd arg optional disk size in MB (default is 51200, for 50G)
Note: making the size smaller than the size in the ova will be nothing but trouble
