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.

There are not enough hosts available 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?

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. 2016-05-11 09:17:30.529 15559 INFO nova.filters [req-6c68100d-420f-43ad-878e-7819a43298e6 5c50e3803049470283f7a9d18e871096 28d5644376ba4d3bab3a30e09a0b28d1 - - -] Filter ExactRamFilter returned 0 hosts 2016-05-11 09:17:30.530 15559 INFO nova.filters [req-6c68100d-420f-43ad-878e-7819a43298e6 5c50e3803049470283f7a9d18e871096 28d5644376ba4d3bab3a30e09a0b28d1 - - -] Filtering removed all hosts for the request with reservation ID 'r-mld1goh8' and instance ID '98c49d72-9d8e-4377-bbe0-6dbef187e75a'.
