Try: qemu-system-x86_64 By default, you use qemu which is a 32-bit emulator. I think SVM is available only to 64-bit guests. The 64-bit emulator is named: qemu-system-x86_64, and don't worry, your CPU will work, despite being 32-bit without SVM. 64-bit part is for guests, not for host. I'm not

Hello I'm using qemu a lot for testing. I have to test some scenarios involving intel-VT machines. Can qemu emulates the intel-VT (or AMD pacifica) behavior on any type of machine? Is it possible? Is it planned? Thank you Eurolines : Voyagez au meilleur prix : http://www.alinto.com/pub/

So, as qemu emulates CPU, does it emulates [pacifica|VT] extensions too? With a patch? Yes, Qemu 0.91, can emulate AMD Pacifica/SVM, according to: http://fabrice.bellard.free.fr/qemu/changelog.html So yes, theoretically KVM should work inside Qemu, but don't expect real-hardware performance.
