while attempting to create VM through heat templates, VM creation is stuck in "Build" status, "Scheduling" task.

From nova-conductor I see following about retrying & timeouting.

RROR nova.scheduler.utils [req-1723f42b-b4f0-435b-9e3f-47b323f96e87 ae2e8beaf0f54275b24a1800fd7b50d9 7c1e142c555543fbb2b5651e58211550 - - -] [instance: fd3b21ff-714a-4682-964c-580f3bcb65a3] Error from last host: <host1> (node <host1>): [u'Traceback (most recent call last):\n', u' File "/usr/lib/python2.7/site-packages/nova/compute/manager.py", line 1926, in _do_build_and_run_instance\n filter_properties)\n', u' File "/usr/lib/python2.7/site-packages/nova/compute/manager.py", line 2116, in _build_and_run_instance\n instance_uuid=instance.uuid, reason=six.text_type(e))\n', u'RescheduledException: Build of instance fd3b21ff-714a-4682-964c-580f3bcb65a3 was re-scheduled: Timed out waiting for a reply to message ID 55ca2a4516d24a31a4d2c5e12ae9044b\n']

Any ideas on what to look for, how to troubleshoot?

Are the instances volume based? Is cinder responding? It also could be related to neutron when it fails to create ports on the compute node. Check all related log files.

No they are not. Cinder is started and responding. Thanks for your help though. Issue is (temporarily?) resolved by restarting services on cntrl node.
