Features of the host CPU are exposed to the guest, but not all of them - that might also be a factor if your host CPU is spiffy enough (disclaimer: I am clueless about x86 cpu features). ISTR, Qt didn't work in certain cases inside VBox b/c part of Qt code checked CPUID and correctly detected that some feature was not available, while some other part of Qt code checked instead, roughly speaking, the CPU generation and incorrectly assumed that the same feature is available in all CPUs of that generation. http://virtualbox.org/manual/ch08.html#vboxmanage-modifyvm and search for cpuid. -uwe
