Re: [openstack-dev] [Ironic] Node uuid and Nova Hypervisor ID
Can you describe the deployment topology you envision -- which service(s) are on what host(s)? Your question seems based on an assumption that ironic is able to control the power state of the nova-compute host _itself_ -- which is not true (*). When using the nova.virt.ironic driver with Nova, you would run a very small number of nova-compute services, and scale out the ironic-conductor services to some degree. Ironic is not a service to manage the power state of the nova-compute host -- it's a separate service to provision Nova instances on bare metal servers (which are, generally, kept powered off unless in use). (*) unless you're using TripleO, in which case your question seems to be mixing the undercloud (ironic) with the overcloud (nova-compute + libvirt/xen/etc), without explicitly explaining how or why you're doing that. -D On Tue, May 6, 2014 at 1:36 PM, François Rossigneux francois.rossign...@inria.fr wrote: Devananda, I get the Nova Hypervisor ID by typing nova hypervisor-list.

Re: [openstack-dev] [Ironic] Node uuid and Nova Hypervisor ID
Hi François, You can hit the Ironic nodes API and filter by instance_uuid. Something like: curl http://ironic:6385/v1/nodes?instance_uuid=blablabla Hope that helps. // jim On May 6, 2014 at 2:28:30 AM, François Rossigneux (francois.rossign...@inria.fr) wrote: Hi all, I need to retrieve the Ironic node uuid from a Nova Hypervisor ID.
