** Description changed: Binary package hint: qemu-kvm Version: Natty Kernel Version: 2.6.38-2-generic x86_64 KVM Version: QEMU emulator version 0.13.0 (qemu-kvm-devel) LibVirt Version: libvirtd (libvirt) 0.8.5 I created a VM using virt-manager. During the installation, the process kvm has a CPU usage goes of 100%. Being aware of the virt-manager [1], bug #707313, (using 100% CPU), I used top to determine weather this was virt-manager of kvm itself. After doing so, I noticed that both, kvm and python processes where more than 80% of usage. So I decided to go ahead and close virt-manager and the VNC window for the current VM. Then, I returned to a terminal to see top's output, and it showed now that the kvm process was the only one with 100% CPU usage. - Note that the CPU usage is only at 100% when doing IO, apparently. + Note that the CPU usage is only at 100% when doing intensive IO, + apparently.
