VMWare Fusion Using Boot Camp

[belt1]

Hi,

I have Windows 7 64-bit installed via Boot Camp. It runs beautifully in Boot Camp but when I try to mount the Boot Camp partition in VMWare Fusion, the speed is less than stellar. This brings me to my question:

Is there a performance difference running Windows by doing a clean install in VMWare fusion versus mounting an already installed Windows Boot Camp partition using Fusion?

Thanks!

You have to things going against you.
1. The performance hit of running a 64bit OS within vmware (make sure you set the type to win7 x64)
2. The performance hit of vmware using the bootcamp partition.

You'll get a better experience if you use vmware's VMDK disk images for your guest os then bootcamp.

Combining both the overhead needed to host a 64bit OS and using bootcamp is certainly going to make the guest OS much slower then running it natively within bootcamp or slower then using a 32bit os within vmware's proprietary disk images.
