More than 2 cores in VMware Fusion?

    I just received my new Mac Pro with 8 cores. Yummi!!! Fastest machine I've ever worked on...

    A tip: I use 4x500 GB Sata disks in raid0 for my system drive. It was a little difficult to install OSX. I had to boot from the DVD, use Disk Util to create the raid, AND then reboot, to have the option of selecting the raid for OSX install. Runs like a charm. About 250 MB/s, and that makes everything load extremely fast :) Careful though! Turn on Time Machine, because your doomed to have a disk failure, at some time, with 4 disks in raid0 ;)

    Now to my question:

    Is there any way to have VMvare Fusion, run on more than 2 cores, let's say 4? I use the machine for extreme rendering (3D stills at 20.000x20.000 pixels 16bit), and two or four cores extra in XP x64 would make a major difference. Even though XP x64 runs perfectly in Fusion, it's not possible to install as a Boot Camp partition, so that's not a solution

    Thanks in advance,


    PS. Did I mention that I also received a 30" ACD? If you work with HD video that's a magnificent display. A full HD image to work on, and screen estate left for the UI. What more could you ask? (Doesn't really do it for 4K RED cam material though ;))

    You should be able to just go into the settings for your VM and select '4 virtual processors' instead of '2 virtual processors'.

    If you haven't already, update Fusion to the latest version. v1 only supported 2 virtual cores, but with v2 they created the option for up to 4 virtual cpu's.
