[Bug 1011925] Re: cpu soft lockup in Centos guest using KVM 0.14.1

[Michael Chapman]

Serge,

I wasn't clear, sorry. The kernel messages are appearing on the guest
and it becomes unresponsive.

Here is the libvirt.xml:

<domain type='kvm'>
    <name>instance-00000092</name>
    <memory>8388608</memory>
    <os>
