Ticket #8474 (closed defect: fixed)
Performance and stability problems on new i7 CPUs (Mac OS X)
|Reported by:||natethegreat44||Owned by:|

Hi, As noted in the forum post at http://forums.virtualbox.org/viewtopic.php?f=8&t=39368, VirtualBox is very slow and leads to host OS freezes on machines with new i7 CPUs (including quad core MacBook Pros and 12-core MacPros).
Disabling VT-x helps with the extremely bad performance, but eventually the host OS will lock up.
I have attached a vbox log file here. This log file was created while booting a pristine windows XP guest and then shutting it down, with VT-x enabled. Guest additions are installed. The entire this guest was running, the CPU on the host OS spiked to 100%.
