Thanks Jon. Your instruction is pretty much the same as the ones I found on VMware forum. I just have to make the time to do it As for performance, my general impression (i.e. no hard benchmark figures) is that Fusion is just slightly slower but much more 'usable' than Parallels. Parallels is fast while working inside the VM but tends to beachball a second or two if I switch from the VM window to another OS X app. Whereas with Fusion there is no delay at all, ever. Of course, YMMV! Would I switch to Fusion when it is released? Yes, because I can see the active participation of VMware engineers on their forum verses the almost non-existant one here at Parallels.
