Also you all talk about that it can get slow if not enough RAM are assigned.. How many do you usually assign to your "Windows virtualization"? I'll have 4 GB total, so what'd you recommend, when i won't be gaming, for XP and Win 7 respectively?![]()
I usually just assign half to the virtual machine, but it depends. It can be changed after the virtual machine has been created, just requiring a restart. If Windows is too slow, give it more memory. If Mac OS X runs too slowly while virtualizing Windows, decrease the memory allotment.
From the sounds of it above, you need to buy Windows OS if you're using Bootcamp, but you DON'T if you're using a VM Ware product, or Crossover...is that correct??
You don't need to buy Windows with CrossOver/WINE. VMware/Parallels/VirtualBox act as completely independent PCs running on your computer, so they do require that you bring your own operating system, be it Windows or Linux.
