Unfortunately, once I got it set up, I found that VBox guest performance simply sucks. The *mouse* isn't responsive. Linux guests see lots of "CPU Locked" errors. Googling turns up lots of problems with VBox on SandyBridge: Mac's running on 64 bit kernels have this problem - running on 32 bit kernels helps. Turning off Intel's SpeedStep has been reported to help. Turning off VT-X in the guest - if it's a 32-bit guest - helps. The last one is the only one that actually helped me. I was wondering if anyone here had run into and solved similar problems? Or if they were running a similar system, and didn't run into that problem? Especially anyone running 9.0 instead of 8.X!
