Comment 11 for bug 1612412

another one test:
 - i've changed aa_profile for neutron_server container from lxc-openstack to unconfined in container config.
 - restart neutron_server
 - ping 8.8.8.8

returns same error.

looks like: xenial + overlayfs without attache_disconected flag = errors "Failed name lookup - disconnected path"

another one test:
 - on installed aio host: lxc-clone --snapshot -B overlayfs -o ubuntu-xenial-amd64 -n test1
 - echo "lxc.aa_profile=unconfined" >> /var/lib/lxc/test1/config
 - lxc-start -n test1
 - ssh test1 "ping 8.8.8.8"

returns same error.
