Where exactly are you stuck? Have you downloaded phpvirtualbox and put it in the Dynamix webserver?
Is phpvirtualbox still not part of the virtualbox package? I thought it was. I thought that was one of the items that it installed from the virtualbox gui. I see it mentioned a lot but dont see how to get it or install it.
EDIT: okay I got phpvirtualbox from sourceforge, and have it extracted. what do I need from here? do I dump all of it into a location, or just a select few items?
vboxwebsrv is installed, but you need something to talk to it. Download phpvirtualbox and put it in the web root you set up in Dynamix webserver.
