Good Day: I am running Gentoo on a HP DV9347cl series laptop and I would like to run a few guest operating systems on top of Gentoo. I do not have much experience and am seeking some advice. Currently using Virtualbox 1.5.4, I got Vista Business running without any problems and it runs pretty smooth. However, Windows is not my concern. I have an upcoming class based on MAC OS X and I would like to attempt to take this class running a virtual machine, for educational purposes! I gave Vista a significant amount of space (10G's) and 1G of memory. My first question, is it necessary to give that much memory to a guest OS (being that I will not be using it for complex movie editing)? I suppose my most significant question is which application works best here, is it Virtualbox, xen, or VMWare? Now here is the catch, when I tried running the OS X install it suddenly crashes and honestly I have not had much time to look into this, assuming it can(t) be done? Is anyone running OS X inside a virtual app? What was the hardest challenge in doing so? I hope someone can provide some input. thanks in advanced!
