<p class="MsoNormal" style="margin-bottom:12.0pt">I've let the deployment run overnight and it failed after almost 4hrs with the errors below. Do you happen to know the config file where I can decrease the timeout? I looked in /etc/nova/nova.conf and in ironic
config files but I couldn't find anything relevant.<br>
<br>
The errors are:<br>
<br>
[overcloud.Compute.0]: CREATE_FAILED ResourceInError: resources[0].resources.<wbr>NovaCompute: Went to status ERROR due to "Message: Unknown, Code: Unknown"<br>
[overcloud.Controller.0]: CREATE_FAILED Resource CREATE failed: ResourceInError: resources.Controller: Went to status ERROR due to "Message: No valid host was found. There are not enough hosts available., Code: 500"<br>
<br>
It is unclear to me why the above errors occur, since in my instackenv.json I declared node capabilities for both the computer and the controller node to be greater than the compute and controller flavors from 'openstack flavor list'.<br>
<br>
However, I've found this link and I am looking over it:<br>

Check also network settings. 4h timeout is the default when something is unreachable.<br>
