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.
