libvirt-bin      1.1.1-0ubuntu8.5~cloud0
libvirt0      1.1.1-0ubuntu8.5~cloud0
python-libvirt      1.1.1-0ubuntu8.5~cloud0

2) #cat /etc/libvirt/qemu.conf
...
user = "root"
group = "root"

I searched GOOGLE, René speaks "downgrading to libvirt 1.1.0 and reinstalling everything. They will ok". But I don't think that.

How to resolve this error?.

Thanks all!
