Today I’ve tried to access virtual disks from DVD to run MapSnack. Interestingly enough it runs, the trick is to make snapshot which can be read-only and remain on DVD – so you don’t need to copy all Gigabytes to your hardrive. Instead you copy on your HD just few MB of ‘delta’ virtual disks which need to be writable. Of course it is slower to read from DVD but for saving a disk space that make sense. So let’s consider following modes of running MapSnack: 1. virtualized and runing from harddrive (current release) 2. virtualized but mostly run directly from DVD (this) 3. native run from DVD as LiveDVD (see previous post) 4. hybrid run – native: small booting iso image which mounts virtual disks virtual: see point 2. Number 4 is target which brings great flexibility.
