I've got four guest OS (2 Window XP, 1 Ubuntu VM, 1 FreeNAS) with guest additions installed on each, hosted on an Ubuntu server (12.10) using a headless VirtualBox (4.2.6r82870) setup.
Currently, I'm using the FreeNAS server (512MB, ~2.5TB)to share between XP and Linux hosts, but I'm wondering if this is just overkill on my host resources (AMD 1045T, 8GB). Would it be better to just create a separate partition on the host dedicated to hosting these files, and then use VB's shared folders ability? Since FreeNAS and its storage is a VM itself, I'm essentially hosting the files on the host system regardless.
Specifically, I'm processing large files (>500MB) and would like to optimize for that. What are some of the drawbacks to the current setup above, and what would be better given the goals in mind?
Many thanks for any advice!
