Things you could check: - on the compute node, nova compute log (DevStack names it n-cpu), are there messages indicating that the node can't contact the placement service.
- if so, find out why. The error message might contain clues. Likely causes are misconfiguration in nova.conf, some networking misconfiguration, firewall etc. Ultimately, the root of the problem is in local.conf, I would guess. - if it can contact the placement service, something is wrong at a different level. Again, I would hope that the compute log contains useful information. -----Original Message----- From: Ramu, MohanX [mailto:mohanx.r...@intel.com] Sent: Tuesday, November 28, 2017 4:47 PM To: Brian Haley <haleyb....@gmail.com>; openstack@lists.openstack.org Subject: Re: [Openstack] Devstack -Ocata - Failed to launch instance on Host After running discover host command also not able to populate the compute node data into Resource_providers table.

There is a section on multinode setup in the devstack repo, doc/source/guides/multinode-lab.rst, that I think covers the issue you're seeing. Assuming your compute node shows up in 'nova service-list' output, you need to run ./tools/discover_hosts.sh to have a cell mapping added for the node. -Brian _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack
