From the compute log info , it seems that cinder had some problem during creating volume, could you show the corresponding cinder log ?

So, from the cinder log, it seems your database cannot be connected by cinder.

  1. parameters max_tries and wait_between of method ComputeManager._await_block_device_map_created should be configurable

  2. Admin event callback API

    Provide an API for external services to send defined events to the compute service for synchronization. This includes immediate needs for nova-neutron interaction around boot timing and network info updates.

  3. Change I2f771d8b: Make libvirt wait for neutron to confirm plugging before boot

Actually, volume with system number like 9e810025-bfee-49d5-a109-b1d6a53afcba been created ,before failure to load, is OK, like it has been done with cinder create --image-id ... . I can create Ubuntu 14.04 instance via this volume in same dashboard env. Created instance will be functional at least via my experience. It really looks like nova-compute tries to load instance too early.

I also tested recompiling /usr/lib/python2.7/site-packages/nova/compute/manager.py , method _await_block_device_map_created as suggested in parameters max_tries and wait_between of method ComputeManager._await_block_device_map_created should be configurable . It doesn't work for me.
