[Bug 1339512] [NEW] libvirtError XML error: cpu feature 'rdtscp' specified more than once

[yanal]

Public bug reported:

Hi there,

I have configured controller node (controller) and two compute nodes
(compute 1 and compute 2) using icehouse openstack on three virtual
machines which run Ubuntu 14.04 LTS.

I'm trying to live migrate one instance from compute1 to compute2
through dashboard/command-line and I got migration error and the status
of the instance is 'migrating'

I check the log /var/log/nova/nova-conductor.log   and I got the
following:

ERROR oslo.messaging._drivers.common [-] Returning exception Migration error: Remote error: libvirtError XML error: CPU feature `rdtscp' specified more than once
