My IMAC processor is 2.53 GHz Intel Core i5, and I'm using Fusion 3.1.2 on mac OS X 10.6.54 host OS, I can run Win 7 64 bit guest OS and Mac OS X Server 10.5.7 (32 bit)well, but can not run Mac OS X server 10.6.2 guest OS (64 bit). When I try to start Mac OS X Server 10.6.2 virtual machine, it always report "the cpu has been disabled by the guest operating system".
I can run Mac OS X server 10.6.2 virtual machine on IMAC with processor Intel Core 2 Duo
I can only find the processor check tool for windows and linux , but didn't find Mac version. So is this the problem with hardware or guest OS ? Why I can run windows 64 bit guest os, but can not run Mac 64 bit guest os ?
try installing same version of OS X 10.6.54 (64-bit) in the guest OS and see it helps.
I finally find the cause and solution:
