Try to run QEMU with "-smp 4".

Thomas thank you for your reply.
I will try each of your suggestions in turn.

-smp 4 did help and this time i could configure 2 cpus in windows.

Now for a very important question.
If hardware virtualization was not switched on in bios will qemu refuse to create more cpus? I just want to know if there are not bogus software cpus or cores created by qemu and that it actually checks it can get real cores from the machine and make it available to the host.

Second question. In the past qemu was lightning fast. However with this newer qemu windows 7 is very slow. It takes about 1 minute to open an application. What can slow it dow so much ? This happens with or without the smp switch. It seems there is some polling botlleneck if i move the mouse in circles in the windows guest, it would freeze for four seconds and then work for about 6 seconds then freeze again etc. What is that about.?

What is the official posting rules in this forum, top post or bottom post ? Thanks
