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.
