if they show up in the service list but not they hyperiors api it<br>
means that the comptue service started and registered its service entry but<br>
something broke it before it could create a compute node recored in the db.<br>
<br>
with ceph the case i have hit this most often is when the keyright used by nova to<br>
get the avaiable capastiy of the ceph cluster is wrong whihc prevent the resoucetack and compute manager<br>
form actully creating the compute node record.<br>
<br>
<br>
it can happen for other reason too but best place to start is check if there is an error in the nova compute agent log and go from there.<br>
