RHBA-2016:1287 - Bug Fix Advisory

トピック

Updated OpenStack Networking packages that resolve various issues are now
available for Red Hat Enterprise Linux OpenStack Platform 7.0 (Kilo) for
RHEL 7.

説明

Red Hat Enterprise Linux OpenStack Platform provides the facilities for
building a private or public infrastructure-as-a-service (IaaS) cloud
running on commonly available physical hardware. This advisory includes
packages for:

• OpenStack Networking service

OpenStack Networking (neutron) is a virtual network service for OpenStack.
Just as OpenStack Compute (nova) provides an API to dynamically request and
configure virtual servers, OpenStack Networking provides an API to
dynamically request and configure virtual networks. These networks connect
'interfaces' from other OpenStack services (e.g. virtual NICs from Compute
VMs). The OpenStack Networking API supports extensions to provide advanced
network capabilities (e.g. QoS, ACLs, network monitoring, etc.)

Changes to the openstack-neutron component:

• With this update, legacy routers can now be migrated to an HA router, and vice versa. This allows users to migrate legacy routers to HA routers. To do so, users must unschedule the router from the existing agents, change the 'ha' attribute to 'True', then re-schedule it. Migration from an HA router to a non-HA router is also possible.

Users can use the following commands to migrate a router to and from HA:

neutron router-update --admin-state-up=False <ROUTER>
neutron router-update --ha=True/False <ROUTER>
neutron router-update --admin-state-up=True <ROUTER>

(BZ#1292527)
