Anthony , Unfortunately, I dropped instance running XEN . In a couple of days, I will reproduce environment and send /var/log/xen/xen-hotplug.log to you. Regarding Libvirt version, I also tested driver with libvirt 1.2.14 , manual build via libvirt-1.2.14.tar.gz ball and upgrade on Ubuntu 14.04.2 after stack.sh completion. I got same error in libxl-driver.log
Thank you.
