Thread-195::ERROR::2013-10-11 15:22:39,508::vm::304::vm.Vm::(run) vmId=`4bad94ad-c338-4ec5-8e5b-9910d58c1854`::Failed to migrate
Traceback (most recent call last):

    Bug 972675 - Fail migration when VM get paused due to EIO

This must be reverted in vdsm or hacked in Engine (do not set abortOnError=True if libvirt < libvirt-0.10.2-20.el6)
