32-bit VT (Intel) definitely exists. If there aren't any 32-bit AMDs with SVM, does SVM even have defined 32-bit semantics? But I see the kvm kernel code can build 32-bit SVM support. I wonder if it has ever been tested :-) > Also, back when I developed it, 32-bit kvm didn't really work > properly. So please let me know what you find out! Do you mean 32-bit kvm on a 32-bit host, or 32-bit kvm inside your SVM emulation? kvm works very well on 32-bit Intel hosts. -- Jamie
