After a large number of reboots the network interfaces doesn't come up any more. The z/VM guest boots fine, unless the missing network. Impossible to bring up network again manually. == Further debug shows that it is the "ip link set enccw0.0.f5f0 up" that is failing with "RTNETLINK answers: Operation not permitted". Looking for further debug assistance in determining why the CAP_NET_ADMIN check for the root user running ip might be failing.
