Virtualbox on Linux

Hi guys, is anyone using XOD desktop on a linux based PC and also using VirtualBox?
I have as my basic daily PC loaded with Linux as the host and do all my work on another Linux Guest - that way I can just copy the whole working OS anywhere and also do complete backups and snapshots. I am new to XOD and the whole Arduino thing - so just getting started.

I was also trying to find a ready made example patch I could try to program my UNO - but could not find anything - not sure where to look or is this something I should be doing quickly in the XOD editor and running it?
