windows guest shows 15 virtual CPU´s in device manager

Hi all,

 

I am  running on kernel 2.6.24, KVM 63 – trying windows guests – working
quite well.

 

…but why tells the device manager that I have 15 CPU`s (QEMU Virtual CPU
version 0.9.1)? The windows task manager is just showing one as expected.

 

I got this issue on winxp sp2 and on vista sp1 (others not tested yet.)

 

Best Regards,

 

Martin

kvm provides 15 cpu slots, but only one of them has a cpu plugged in.  
Apparently device manager shows the slots, not the cpus.

You can populate a cpu slot at runtime, but whether the the guest will 
use the cpu depends on the guest OS.
