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 <[email protected]> wrote: > Devananda, > > I get the Nova Hypervisor ID by typing "nova hypervisor-list". > I am developing a resource reservation service and the reservations are > attached to a Nova Hypervisor ID. > I would use Ironic to put the nodes on standby mode when there is no running > instances. > This is why I need to get the Ironic node UUID from a Nova Hypervisor ID... > > "http://ironic:6385/v1/nodes?instance_uuid=blablabla"; is not a perfect > solution : without running instances, you cannot retrieve the node UUID... > > Thanks. > > > Le 06/05/2014 22:05, Devananda van der Veen a écrit : > >> François, >> >> Can you clarify by way of a CLI example what exactly you mean by "nova >> hypervisor id"?
