Hi Serge.
No I'm not. In fact I thought this was already marked as invalid or
something :).
Cheers,

Well golly gee willikers, I think I now have the same problem.

I can reproduce this using kvm from the command line, so libvirt appears
unrelated:
kvm -hda lucid.img -m 512M -smp 2 -vnc :1 -redir tcp:::22 -cdrom
lucid-server-amd64.iso
The simplest 'bzr branch grub grub-b' pins my cpu.

And yet when booted from cdrom, cpu utilization stays around 10%.

@Andres,
qemu-kvm has been updated to 0.14.0~rc1. Could you let us know if the
issue persists?

Hi Serge,
I haven't experienced the same behavior as before 100% CPU with latest
qemu-kvm. However, during installation of a natty VM, while doing IO,
the CPU load is still a bit high sometimes ~70-80%. But, overall I can't
seem to reproduce this problem. The kvm command used by libvirt now is:
All right, so this comes down to an incompatibility between maverick's
versions of libvirt and qemu - libvirt is using QED, but qemu-kvm
doesn't yet know about it. The '-drive file=X,if=none device=...'
format, in particular, is QED.

Could you try running the following command:
kvm -m 512 -smp 2 -cdrom /home/roaksoax/.cache/testdrive/iso
/ubuntu_natty-server-i386.iso -drive
file=/home/roaksoax/.cache/testdrive/img/testdrive-disk-
J_PcC_.img,if=virtio,cache=writeback,index=0,boot=on -usb -usbdevice
tablet -net nic,model=virtio
From an overall CPU load of 20%, after launching and leaving the VM not
doing anything (In the menu requesting keyboard language for the
installation) it goes up all the way to ~60%, and during installation it
goes till ~70%of CPU load.
This results are about the same as when launching with the
I'm sorry, something went wrong in my editing the previous post. The
command I had wanted you to try was:
kvm -m 512 -smp 2 -cdrom /home/roaksoax/.cache/testdrive/iso
/ubuntu_natty-server-i386.iso -drive
file=/var/lib/libvirt/images/natty1.img,if=virtio,cache=writeback,index=0,boot=on

Thanks Andres, the .xml looks fine, but the command spawned by libvirt
certainly does not. In particular, the drive definition for natty.img
looks bogus, with its 'if=none'.
If you close virt-manager and start the vm with 'virsh start natty1', do
you get the same command?

Yes is the same command.
When I installed the VM i chosed the Ubuntu Natty profile (I though this
default to VirtIO?). Maybe this is the reason!
