I'm facing similar problem in openstack/nova-compute context
We are using libvirt as default KVM to spawn the instances.
I faced the problem ONLY when the directory where it creates the console.log was nfs mounted (Not local disk path)
Indeed I too have <serial> in the XML file -which is where the problem occurs.
But when using local file system, everything works OK.
