Open Stack

Hi Satish, 

so the problem seems to be the following:

You are telling the under cloud to use these flavors with: 

(undercloud) [stack at tripleo instance]$ openstack overcloud deploy
--templates   --control-scale 1 --compute-scale 1 --control-flavor
control --compute-flavor compute

Your flavor for control, compute etc. says it needs at leats 4GB of RAM,
 40GB of Disk etc. but you only have instances providing 2GB of RAM.
This is way nova is complaining about not finding a valid host. 
The scheduler simply can not fulfil your request for a host with those resources available. 

To get around this you could either create VMs with a bit more ram etc, 
or you need to change the flavors - but i’m afraid 2GB of ram is to little. 
If you have the resources try to use at least 8GB per control or compute
 node if not you could try with 4GB and swap but i’m not sure if this works well enough.
