Here is the latest version of the popular CPU emulator for Windows users :

I generally use bochs for things like OS dev, switching to PM, activating cores, going to long mode.
Does qemu do smp in 64-bit? I thought, way back, that bochs and qemu were the same, with qemu the poor cousin.

QuoteKernel Based Virtual Machine

KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko. KVM also requires a modified QEMU although work is underway to get the required changes upstream.

Does KVM support SMP guests?
Yes. Up to 16 CPUs can be specified using the -smp option.

KVM is not for Windows, so it's off-topic.

Qemu for Windows was once pretty good, but today it's a neglected branch with lots of problems. Just downloaded the newest version and it still crashes as soon as I press Ctrl-Alt-F to switch to fullscreen mode. Also, the keyboard emulation has become very "slow".

The last usable version of Qemu for Windows was 0.91.

What is good for me is that qemu is portable. You can put a copy of your qemu directory to your USB memory and it will work on another computer. Also, qemu works on Windows PE 1.x environment.

What do you use QEMU for Vortex?
I am curious.

Feel free to visit the WinBuilder section of the reboot forum and try to figure out the reason :
