I am trying to integrate the Ironic service with other openstack services.
I am using liberty release of openstack.
installed and configured the Ironic service.
here is the setup:
1: all openstack services are deployed on VM
2: controller is on one VM (along with other services) and compute is on
3: one bare metal machine / desktop is there which i want to provision
using the ironic service.
4: nova compute service which runs on compute node is serving hypervisor
for VMs and another nova compute service which is running on controller is
acting hypervisor for bare metal node ...
5: so actually i have hybrid model of VMs and physical server for openstack
6: i am using pxe_wol driver to boot the node. using ironic service also i
can boot the node.
so, this is the brief about the environment setup which i have as of now ...
the issue is , when i am trying to launch the instance from horizon
dashboard .. i am getting above error
in the scheduler log, here is the output.
