From 298115b94b881146fb82abc4e64d0e4f668d20e4 Mon Sep 17 00:00:00 2001 From: Han Zhou Date: Thu, 4 Oct 2018 13:01:09 -0700 Subject: [PATCH] ovs-ctl: Add new option to use short hostname. Current ovs-ctl forces to set full hostname in external-ids. In some situation users may want to set short hostname. For example, in OpenStack - OVN integration, Neutron uses the host-id provided by Nova, which is usually short hostname, to set "requested-chassis" in OVN. The mismatch in hypervisor's external-ids:hostname setting causes OVN port binding failure. It can be overridden to short name but a openvswitch restart using ovs-ctl would again set it to full hostname. This patch ensures in such use cases --no-full-hostname can be specified to ovs-ctl to set short hostname instead.
