Hello everyone, I'm not sure if this is the correct mailing list with my topic. But the website says that end user's questions are welcome. So please give me a hint if this is the wrong place. On the host: # rpm -qa | grep kvm kvm-0.12.5-1.2.1.x86_64 # uname -a Linux alphawkst 2.6.34.7-0.7-desktop #1 SMP PREEMPT 2010-12-13 11:13:53 +0100 x86_64 x86_64 x86_64 GNU/Linux The guest is a Windows XP 32 Bit, and everything was fine until yesterday. For no obvious reason, as soon as the guest starts one of the two cpu cores has 100% load if started with -smp 1, and both cpu cores have 100% load if started with -smp 2. There is no process inside the guest that generates this load. Instead, the guest is idling at 0-5% (that's what the windows task manager gives in the status line). The guest is started with: # qemu-kvm -M pc-0.12 -enable-kvm -smp 2 -m 1024 -name XP2Use -uuid ad148b2d-b99e-c9de-7c0c-4ab6b716f3ec -rtc base=localtime -boot c -drive file=/var/lib/libvirt/images/XP2Use.img,if=ide,index=0,boot=on,format=raw,cache=unsafe -net nic,model=rtl8139,vlan=0,macaddr=52:54:00:5d:a2:a5 -net tap -vnc 127.0.0.1:0 -k de -vga std -usbdevice tablet The same happens if the machine is started via virt-manager, in which case I find the following in the process list: # ps aux | grep qemu root 12909 100 13.1 1231668 1076428 ?

And again, if I'm wrong here, please point me to the right place.
