Re: [Qemu-devel] did the qemu can emulate the whole system with the processor that without support the "virtulization and kvm"?

[tugouxp]

Hi alex:
    now my host machine did not have the "/dev/kvm" nodes and no chance to make 
it exists. 
so i want to know whether the "/dev/kvm" is  mandatory  for qemu to emulate the 
whole system. 
so i can make the emulation without the support of kvm mechanism.


thanks for your support.!
