It seemed that I had solved in the live migration of the VM but it repeats this rorry that I do not understand .... Sometimes it signals me that the conntrack is disabled sometimes not !
I also noticed that only on a node sometimes appears the error that you see in the attachment. I try the mistake that warns me about the state of the conntrack there is no more !!
