During the deployment the libvirt close connation with nova-compute. libvirtError: End of file while reading data: Input/output error\n' [closed]
I don't think that it's an authentication because the nova-compute can make the inventory on compute node.

Does it happen all the time? Are you able to launch any instance? What is your configuration?
There seem to be many possible causes for this error, including config errors (e.g. https://bugs.launchpad.net/nova/+bug/...).
looks like that there is an issue on libvirt 2.0 with Mitaka and Newton, the ticket is telling to downgrade the libvirt to 1.7 same version of Liberyt. Any idea about how can be done the downgrade ? https://bugs.launchpad.net/nova/+bug/1649527 (https://bugs.launchpad.net/nova/+bug/...)
