These are my (bdwheele) brainstorming notes for the VM image...I'm still testing this.

VM Configuration

Base OS Install

Avalon Install

Demo Content

VM Image Prep

 

Adding the demo batch increased the size of the VM download from 3.2G to 7.4G.  Partially its because we've make derivatives and there's really new content on the VM.  But for a bigger reason, any disk space that gets allocated is stored in the image file – the VM doesn't know what's being used and what isn't.  Since we download a largish package, untar it, and create a bunch of temp files, the VM disk image has a bunch of unused (from the OS point of view) disk that it still has to keep track of.  Future research should include how to 'unuse' the disk space.

"zerofree" should do the trick, when combined with vboxmanager modifyhd <name> --compact
