I have been using a BootCamp partition run as a virtual machine in parallels for a few weeks and it is working fine. I chose this solution to be capable of run windows directly with bootcamp if I need real native performance. However, I have been doing normal work for weeks and it has been unnecessary to do that: the performance of windows as a virtual machine is good enough. So my question is, should I use a purely virtual machine instead of "virtualize" the bootcamp partition? which advantages will I gain (fast start, stop machine feature...)? Thanks!
