Open Stack

try with a tiny image and see what you get. If you suspect that the
available RAM is the issue, use the tiny flavor to begin with and see what
happens. if tiny one is ok, you at least can remove some of the factors and
focus on your baremetal.

Thanks.

thanks.
i observed that, instances_path option was not there in the nova.conf
file , i added the same and restarted the service , still the issue
persist
as per the log, ExactRamFilter filter has some issue
i have created one flavor called baremetal. so does that mean that , the
RAM which is assigned to the flavor show exactly match the RAM which is
there on the physical server ?
my baremetal physical server has near about 15 GB RAM, so the exactly same
RAM should be present in the baremetal flavor ?

@vikram, i did not understand what you said, are these commands?

Regards

   in the nova.conf file i have commented out this and tried creating
   instances but still the issue.

   #scheduler_use_baremetal_filters=True

     You could try dropping the filter from scheduler_default_filters in
     nova.conf

      Hello,
      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 another VM
      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 private cloud.
      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.

      now i dont understand what is the meaning of "ExactRamFilter
