<p>Welcome to OpenStack! I think the joy of troubleshooting it is
one of its main selling points. <br>
</p>
<p>The conductor log says "<i>libxenlight failed to create new
domain</i>" on various nodes. You should check the nova-compute
logs on those nodes for relevant messages. I suspect an
ill-configured interface between Nova Compute and libvirt/Xen. In
other words, double-check the libvirt and xen sections of
nova.conf on those nodes.<br>
</p>
<p>Then there is this message "<i>Invalid </i><i>input for field
'identity/password/user/password': None is not of type 'string'
....</i>". This is often caused by incompatible software. I.e.
you installed Openstack components that don't fit together. Might
also be caused by a configuration error.<br>
Or it's an ordinary bug, but it seems to occur on node 2 only.<br>

</div>
<div>And libvirt and Xen have been successfully installed
on all compute node I have without any problem.</div>
