The devstack default limit enforcement for glance defaults to 1GB, and unfortunately this is too small for many to use larger images such as centos which includes hardware firmware images for execution on baremetal where drivers need the vendor blobs in order to load/run. Sets ironic-base to 5GB, and updates examples accordingly. Depends-On: https://review.opendev.org/c/openstack/devstack/+/801309 Change-Id: I41294eb571d07a270a69e5b816cdbad530749a94

Ironic multitenant networking and DevStack
|
|
==========================================
|
|
|
|
This guide will walk you through using OpenStack Ironic/Neutron with the ML2
|
|
``networking-generic-switch`` plugin.
|
|
|
|
|
|
Using VMs as baremetal servers
|
|
==============================
|
|
|
|
This scenario shows how to setup Devstack to use Ironic/Neutron integration
|
|
with VMs as baremetal servers and ML2 ``networking-generic-switch``
|
|
that interacts with OVS.
|
|
|
|
|
|
DevStack Configuration
|
|
----------------------
|
|
The following is ``local.conf`` that will setup Devstack with 3 VMs that are
|
|
registered in ironic. ``networking-generic-switch`` driver will be installed and
|
|
configured in Neutron.
