All,
I'm working to add baremetal provisioning to an already-existing libvirt
(kvm) deployment. I was under the impression that our
currently-existing endpoints that already run
nova-conductor/nova-scheduler/etc. can be modified to support both kvm
and ironic, but after looking at the ironic installation guide
(https://docs.openstack.org/ironic/latest/install/configure-compute.html),
this doesn't appear to be the case. Changes are made in the [default]
section that you obviously wouldn't want to apply to your virtual
instances.
Given that information, it would appear that ironic requires that you
create an additional host to run nova-compute separately from your
already-existing compute nodes purely for the purpose of managing the
ironic-nova integration, which makes sense. However, the ironic
documentation at
https://docs.openstack.org/ironic/latest/install/configure-compute.html
states that:
"The following configuration file must be modified on the Compute
service’s controller nodes and compute nodes"
right before it lays out the minimum config requirements for nova <->
ironic integration, which suggests additional service requirements
beyond just an extra nova-compute. Do we also need to run separate
instances of nova-scheduler, etc. as well? I can't seem to find any
documentation that speaks to this. The current ironic documentation
seems to focus on a baremetal-only deployment scenario.
Currently running Pike.
Thanks in advance,
