Open Stack

Hi Wodel,

Yes, it's possible to deploy openstack with tripleo using VMs and
nested-KVM for the compute node. I personally use this tool on my
hypervisor to do it.

  https://github.com/cjeanner/tripleo-lab

By trying to get tripleo working with nested KVM without using a tool like
the above you might eventually create your own version of the same tool
though using the above helps you skip those steps.

The issue you're hitting from the error message below looks like the Nova
scheduler on the undercloud not finding an Ironic node that satisfies the
scheduling criteria. This can be debugged but you might find it easier to
just not have the problem by letting another tool deal with this for you.
Also, with wallaby and newer tripleo does not use Nova on the undercloud
and instead the recommended deployment process is to use metalsmith as
described here:

https://docs.openstack.org/project-deploy-guide/tripleo-docs/latest/provisioning/baremetal_provision.html

You also have the standalone option of using tripleo on a single VM:
