Excuse me, but it is a bit unclear what you did.

Several questions arise:
a. Qemu now is able to emulate SVM on non-SVM old 32-bit processors ?
b. Qemu now is able to emulate SVM on SVM processors ?
c. Qemu now is able to emulate SVM on VT processors ?
d. How fast it works ? (theoretically, or benchmark results )

Anyway it's nice to hear about this feature.

Hi Alexey,

I implemented SVM in the qemu emulator (not kqemu, not kvm, but the real emulator), so you can use SVM in qemu on _any_ platform qemu runs on - even on PowerPC.

Basically concerning speed I did not do any benchmarks, but as far as I can tell the ratio real machine:kvm and qemu:kvm are about the same. So the virtual machine is about 5-10% slower compared to the emulated machine.

Hope I could clarify this,

Alexander Graf
