Hi,

I'm trying to deploy OpenStack via TripleO quickstart in AIO / virt mode and I'm getting by the last step deploying the overcloud the following "Heat Stack create failed" message (There are not enough hosts available, due to Configuration has 4 errors, fix them before proceeding ????).

After running openstack overcloud deploy I'm getting Configuration has 4 errors, fix them before proceeding: (and I guess the problem lies somehow here with the "incorrectly configured driver_info"):

[stack@undercloud ~]$ openstack overcloud deploy --templates

Node uuid=a62116c4-1daf-45e9-aa2d-ef8a4effdc20 has an incorrectly configured driver_info/deploy_ramdisk. Expected "482254d3-4b0c-4c3f-b2ba-bdf34badbbd3" but got "None".

Node uuid=a62116c4-1daf-45e9-aa2d-ef8a4effdc20 has an incorrectly configured driver_info/deploy_kernel. Expected "482254d3-4b0c-4c3f-b2ba-bdf34badbbd3" but got "None".

Node uuid=cfc60017-36e8-4808-842d-8c65ffb5e4b1 has an incorrectly configured driver_info/deploy_ramdisk. Expected "482254d3-4b0c-4c3f-b2ba-bdf34badbbd3" but got "None".

Node uuid=cfc60017-36e8-4808-842d-8c65ffb5e4b1 has an incorrectly configured driver_info/deploy_kernel. Expected "482254d3-4b0c-4c3f-b2ba-bdf34badbbd3" but got "None".

Configuration has 4 errors, fix them before proceeding. Ignoring these errors is likely to lead to a failed deploy.

By the way I tried to get the stable liberty and the latest mitaka working with TripleO, no either worked.
And tried also Lars's tutorial here:

http://blog.oddbit.com/2016/02/19/deploy-an-ha-openstack-development-envir/

had not so much luck, but could learn a lot and would prefer to learn more by running the ansible playbooks by hand as described by Lars.

Any help / advice is much appreciated.

Thx,
